DOOR OR WINDOW SECURITY SYSTEM FOR MOUNTING AT A DOOR OR WINDOW FRAME

The present invention relates to a door or window security system and apparatus that utilises both mechanical and electronic actuation of a locking bolt to secure a door or window in position relative to the frame, and in particular, although not exclusively, to a door lock mounted at the door or window frame.

It is common for modern buildings to use electronic locks on their doors and windows in place of more conventional mechanical locks that require traditional physical keys. Electronic locks are compatible with sophisticated electronic key cards such as i) radio frequency remote key fobs (RFID fobs) that allow a user to remotely active and deactivate the lock, and ii) proximity tabs (RFID tabs) useable with a key card reader located at the door or window.

The use of electronic locks and particularly electronic key cards provides additional security and functionality as the electromechanical lock may be positioned so as to be more difficult to access whilst the key cards and/or system may be programmed to operate on various recognition criteria controllable by a user.

US 5,609,051 discloses a keyless entry system for use with a deadbolt latch mechanism. The entry system comprises a ratchet mechanism engageable with a solenoid to actuate the deadbolt. Au electronic controller is provided to control the solenoid following entry of a security code at a keypad mounted in close proximity to the door.

WO 00/77330 discloses an on-line door mounted electric lock controllable by an on-line system in which a central station communicates with various elements of the security system to provide a remote controllable locking mechanism.

US 2005/0199019 discloses a remote control security device in which a mechanical lock is operated via an electronic signal generated from a remote source, such as an electronic key fob, or the lock itself. The lock may include a user interface to allow unique unlock signals to be entered or deleted from the lock memory.

US 2007/0056338 discloses an electromechanical door lock in which a solenoid is controlled via a wireless controller. The controller is configured to receive a wireless signal from a remote key fob and energise the solenoid to move the deadbolt between engaged and disengaged positions.

One disadvantage with conventional electronic door lock systems is the susceptibility to 'tampering' with the electronic components of the system to circumvent the lock. For example, door or window mounted electronic locking mechanisms are required to be powered using hardwiring. This typically involves the wire traversing the gap between the door and frame which in turn presents a region vulnerable to tampering due to the accessibility of the relatively accessible wiring.

A further problem with conventional electronic based locks is the dependence upon a supply of power to the electronic components in order to actuate the locking mechanism between an engaged and a disengaged position. Fluctuations and in particular termination of power, failure of electronic hardware or firmware and/or a loss of communication between electronic components can present a serious problem as a door or window may be temporarily frozen in an undesired locked or unlocked state.

What is required therefore is an electronic and mechanical lock system that provides the functionality and convenience of an electronic locking system having an enhanced tamper resistance and parallel mechanical override and control.

The inventors provide door or window security apparatus in which the mechanical lock or latching mechanism is configured to be mounted at, and in particular in, a door or window frame such that the bolt is thrown from the frame into the door or window to provide the locking action. This avoids the need for wiring to traverse the interface between the frame and door and considerably increases the security of the system. Additionally, any electromechanical components of the system may be hardwired conveniently and in a manner so as to increase security of the system by embedding the components, and in

particular hardwiring of the system, within the walls of the building and/or additional security shielding.

The system has been designed to allow 'keyless' entry to a property with an emphasis on keeping the system easy to use and familiar to new users.

The main door lock is electromechanical that is normally operated electrically but which also has a mechanical override facility. The lock is mounted in the door frame and throws its bolt into a strike plate in the door. This arrangement ensures that the security of the system is not compromised by the need to pass data carrying cables and power to the door.

A RFID fob that transmits a signal upon the press of a button is used to unlock the door so that it can be pushed open. This can be done at some distance and allows the user to enter the home while carrying bags and boxes for example. It is also an advantage in poor light conditions, especially to the elderly or disabled.

An RFID tab, can also be used to unlock the door. The tab is held close to a wall mounted reader that is integrated into the system.

An internal door handle is provided and is operated by the user in the same way in which a conventional door handle is operated. An additional small handle on the door frame adds additional functionality as well as providing a mechanical override in the unlikely need for emergency exit during system failure. There is also a mechanical key override so that the door can be locked and unlocked from outside during any such system failure.

The electronic system is configured to continually monitoring itself to check house security and to detect unlock and lock signals. The system is mains powered with provision for a battery backup in the event of power failure.

An internal control panel is used to read status information for the system as well as to manage the electronic keys. The keys, RF fobs and RFID tabs, are assigned a name by the homeowner and can easily be added to or removed from the system. Each key is unique and a rolling code, conventionally referred to as a hopping code, is used to prevent replay attacks.

Figure 1 illustrates a door 100 mounted within a frame 101 viewed from an external side of a building 102. The present security system comprises an externally mounted interface 103 comprising a proximity reader 106 configured to read an RFTD tab to deactivate the lock and gain access to the building.

The external interface 103 further comprises a first light 104 and a second light 105.

Additional buttons may be integrated into the interface 103 including, for example, a door bell (not shown). Lights 104, 105 are used to indicate to a user the status of the security system and in particular an unlocked and a locked state.

Figure 2 illustrates the door 100 viewed from an internal side of the building 200. The security system further comprises a control panel 201 mounted at the internal wall 200 in close proximity to door 100. Control panel 201 comprises an integrated display 202

configured to display information relating to the status of the system. Panel 201 further includes a keypad 203, scroll wheel 205 and additional functional buttons 204. Control panel 201 has additional illumination means (not shown) such as coloured lights to provide additional lock status indication.

Both the external interface 103 and the control panel 201 comprise a receiver (not shown) to receive signals from an RFID transmitter, such as an RFID fob, and other remote transceivers associated with the security system.

A handle 209 is mounted on the internal side of door 100 and is operable by rotation to unlock the locking mechanism illustrated in figure 3. Handle 209 is mounted at door 100 via a mount 210 which comprises an internal electronic switch 208. Switch 208 is activated by the rotation of handle 209 through a predetermined angle. A transmitter (not shown) is housed with housing 210 and is configured to send an RF signal to the receiver of the main system to disengage the lock and allow the door to open. Switch 208 is powered by a suitable battery (not shown) mounted within door 100.

The system further comprises a door frame mounted handle 207 mounted upon a housing 206. Handle 207 provides electronic and mechanical actuation of the lock mechanism so as to provide a mechanical override capability in the event of electronic system failure.

Referring to figure 3, a mechanical lock or latch 301 is mounted within the door frame 101. The lock mechanism comprises a bolt 302 housed within lock 301 with housing 305 in a retracted disengaged position and configured to shoot from housing 305 towards door 100 to an extended engaged position.

A strike plate (or keep) 303 is mounted at door 100 and comprises a receiving cavity 304 into which bolt 302 is configured to shoot in the extended engaged position. Accordingly door 100 is locked in a position against frame 101 when bolt 302 is located within cavity 304.

Figures 4 to 8 illustrate the electromechanical door frame mounted handle 207 in further detail. The rotatable handle 207 is mounted upon a series of shafts 400, 401, 404 extending from handle 207 through the door frame mounted mechanism 206 to interface with the mechanical components of the latch 304 connecting to bolt 302. A plurality of washers 405 are positioned between selected components of the door frame mounted handle mechanism to provide the required stability, spacing and frictional contact between the components.

A drive disc 406 is mounted on shaft 404 and comprises two lugs 500 projecting from one of its faces. Disc 406 comprises a notch 501 to receive an elongate latch 407 so as to prevent rotation of disk 406 and ultimately movement of bolt 302. The latch projection 407 comprises a knob 408 for position through an aperture 403 within an external housing 300. A cover tab 402 positions over knob 408 and is operable by the user grasping tab 402 and moving it vertically so as to displace latch 407 to and from notch 501.

A clutch mechanism 409 is also mounted on shaft 404 and comprises a rotatable disc 420 comprising two elongate slots 410 extending through disc 420 at opposed regions. Slots 410 are configured to accommodate lugs 500 of drive disc 406. A coil spring 412 is positioned intermediate between clutch disc 420 and a switch control disc 413. Disc 413 comprises a notch 414 formed in its circumferential surface. Notch 414 comprises two opposed surfaces 415 configured to contact an electronic switch 416 housed within an internal housing 419 mountable directly on the door frame 101. Switch 416 comprises a conductive material and is hardwired to the control circuitry of the security system capable of sending a signal to the lock mechanism so as to actuate the bolt 302 via a suitable electronic actuator detailed with reference to figure 1OA and 1OB.

Clutch disc 420 comprises two camming surfaces 411 formed at opposed regions of its circumferential edge. Cam surfaces 411 are configured to sit against and buffer blocks 417 biased onto cam surfaces 411 via spring mountings 418.

Handle mechanism 207, 206 is operable to provide electronic actuation of bolt 302 and mechanical actuation, as an override facility in the event of electronic system failure. To provide electronic actuation a user grasping handle 207 rotates the handle from a rest

position illustrated in figure 7 to a first angle value of approximately 45 degrees illustrated in figure 8. The rotation of handle 207 rotates disc 406 and switch disc 413 such that one of the notch faces 415 contacts switch body 416 to close the electronic circuit and relay a signal to the system control circuitry. This in turn fires an electronic actuator (not shown) that acts upon bolt 302 to move bolt 302 between the retracted and extended positions.

Rotation of the handle 207 from the rest position of figure 7 to the electronic actuation position of figure 8 causes lugs 500 on disc 406 to rotate within the elongate slots 410 of the clutch mechanism. Accordingly the clutch operates to disengage rotation of shaft 404 from a corresponding shaft (not shown) interfaced with the lock mechanism 301.

Once handle 207 is rotated from the electronic actuation position of figure 8 to the mechanical actuation position of figure 9, clutch 409 is disengaged and the lock mechanism shaft (not shown) is caused to rotate by rotation of shaft 404. That is, further rotation of drive disc 406 causes lugs 500 to press against the extreme ends of the slots 410 within clutch disc 420 causing of the clutch disc 420 to dislodge cam surfaces 411 from their rest position against buffer blocks 417 at internal mounting 419. The rotation of the lock shaft (not shown) provides direct mechanical actuation of bolt 302 without requiring additional or intermediate electronic components.

Spring 412 acts upon handle 207 at all times when displaced from the rest position illustrated in figure 7. Rotation of handle 207 to the positions of figure 8 and 9 provide movement of bolt 302 from an engaged extended position to the retracted disengaged position. The handle mechanism of figures 4 to 9 is further configured to lock the door by actuation of the bolt 302 from the retracted to the extended positions. This is achieved by rotation of handle 207 counterclockwise from the rest position of figure 7 to an angle of approximately 110 degrees counterclockwise. As with the clockwise rotation, this provides rotation of the lock shaft (not shown) to provide mechanical actuation of the bolt 302.

Figure 1OA illustrates selected electronic components of the security system comprising a main control panel 201; a main electronic box 1001 having internal PCBs 1020 and auxiliary battery supply 1021; a first solenoid 1002; a door sensor switch 1003; a latching

mechanism 1004; a frame lever sensor switch 1005; a second solenoid 1006; an RF (RFID) fob 1007; an RFID tab 1008; and the external interface 103. Additional external lighting components 1000 may be provided and interfaced with main box 1001.

First solenoid 1002 provides an electromechanical actuator interfaced with latch mechanism 1004. Activation of solenoid 1002, in turn provides movement of bolt 302 between the retracted and extended positions to unlock and lock the door, respectively. A second solenoid 1006 may be provided to act upon additional bolt and latch mechanism to provide further security via the use of multiple bolts.

A door sensor switch 1003 is mounted at door handle mounting 210 to provide electronic actuation of solenoid 1002 and in turn movement of bolt 302. Similarly, a sensor switch 1005 is provided at the door frame handle mechanism illustrated in figures 2 to 9 and operates in the same way as door sensor switch 1003 to actuate bolt 302 via solenoid 1002.

Receivers (not shown) housed within control panel 201 and external interface 103 are configured to receive coded signals from door and frame switches 1003, 1005 and to receive signals from RFID fob 1007 and RFID tab 1008. These signals are then processed to actuate solenoid 1002 to move bolt 302 between the locked and unlocked positions.

Figure 1OB illustrates an alternative optional wiring configuration of the various electronic components of the system as shown in figure 1OA.

Figure 11 illustrates the various status indication means, such as external and internal lighting of the system, together with the display panel, so as to allow a user to conveniently recognise the status of the system and the various electronic and mechanical components. The system is configured to indicate to a user an unlocked status 1100 via lighting 1103, sounds 1105 and display panel 202. Similarly, when the door or window is open 1101 the system provides this status information via lighting 1103, sounds 1105 and display 202. Finally, when the system is locked 1102, the status is indicated to a user via lighting 1103, sounds 1105 and display 202.

Figures 12 to 17 further illustrate the illumination, sound and display indications given to a user in response to the status of the various electronic and mechanical components and in response to user commands input to the system via external user interface 103, control panel 201, fob 1007, tab 1008, frame handle 207 and door handle 209.

Figures 18A to 18C illustrate the menu system of the security system accessible through the control panel 201.

Example System Elements and Operation

The system uses an opera maxima mortise motor lock as the electro-mechanical locking device. This is mounted into a doorframe and operates into the striking plate (keep) in the door.

The opera maxima electric lock has a swinging deadbolt in hardened steel with an integral mechanical override operated by European cylinder. The bolt position is controlled by an opto-electronic circuit and a magnetic sensor with a normally open (N.O.) contact is used to monitor door position.

External hardware:

• proximity RFID reader (103);

• keyhole (hidden) - for emergency master key access;

• door puller (to close door upon exit - this may be substituted by an automatic door closer working from the inside); • feedback hardware with LED lights and sounds (optional, i.e. sounds can be disabled by user). The LEDs are green for unlocked, red for locked, reverting to white after 20 seconds;

• a facility to integrate existing external lighting on the property; and

• sounder - moisture resistant and hidden.

Internal hardware:

• an opera lock (301) houses a swinging deadbolt (302) in hardened steel (35mm x 14mm with an extension of 40mm). This lock case is fitted in the door frame (101);

• solenoid lock(s) (1002, 1006), actuate from the frame (101) to the door (100). The Solenoid(s) is powered to engage (lock), and as a failsafe, revert to an unlocked state when not powered. The solenoid(s) always withdraw if the frame handle is turned and when a master key turns the latch cylinder. The solenoids are controlled separately from each other and from the lock signal, this allows independent operation for power conservation etc;

• internal door handle (209) - the door handle is required to pull the door open from the inside. Upon turning it, an internal RP transmitter (battery operated) is activated, sending a signal to the control box (1001) which sends a command to withdraw the lock bolt (302);

• rotating frame handle (207), which has a direct mechanical link to a European cylinder, mechanically overrides the opera lock. The frame handle is a direct mechanical link (equivalent to thumb turn) and does not rely on power, system circuitry or firmware. The frame handle housing incorporates a stop knob (402) and incorporates a switch (416) which sends a hard wired signal to withdraw the lock bolt and allows a signal to be sent to withdraw the solenoids when the frame handle is in its down position. When the stop knob is engaged the lock bolt and solenoids remain in an unlocked state. The solenoids are enabled .to re-lock once the frame handle is released (including when stop knob is disengaged) providing the door is in its closed position;

• main box (1001) - hidden box containing a transformer, back-up batteries, battery recharge circuit, connection blocks, expansion PCBs. Located in a dedicated wall cavity, shielding or suitable cupboard; and

• control panel (201) (not on door or frame but typically adjacent to door) comprises integrated display and data input interface and alphanumeric keypad. Has red and green for additional lock status indication. Incorporates RF receiver; and three override buttons for temporary disabling functionality. The RF receiver is located within the control panel.

Access equipment:

• RFID tab (1008) - small passive device. Must be held in close proximity to the RFID reader (106);

• RF fob (1007) - active transmitting device (uses battery power). Also has passive RFID transponder incorporated in case of battery cell failure;

• RF master fob (1007) - active transmitting device. Uses battery power. Also has passive RFID transponder incorporated in case of battery cell failure. Incorporates fold out physical key; and

• Physical key - a high security mechanical key that allows access during system failure.

The system comprises a relock function which may be set by the home owner in the system setup menu. In effect it allows the door lock to be set to emulate either of the two main types of door lock, i.e. a night latch or a deadbolt lock.

• night latch - a lock which automatically locks when the door is shut. Manually operated from inside (and usually by a key from the outside). Usually provided with a stop knob to hold the latch bolt retracted. Often referred to as a Yale™ lock;

• deadbolt lock - a lock with bolt that, when locked, is fixed in position and cannot readily be pushed back into the lock case. Often referred to as a mortise lock.

The relock functionality is a setting in which the door lock (and solenoids if used) is automatically locked upon closing the door. Door lock also automatically locks once the frame handle is released e.g. after latched mode is disabled. The relock function is different to, and is separate/independent from an autolock function. The following describes the operation of the security locking system with the relock function engaged with reference to figures 12 to 18C.

Relock yes - door automatically locks itself upon closing the door. Also relocks itself once the frame handle is released e.g. after latched mode is disabled.

Relock no - door needs to be actively locked by the user.

• upon exiting the premises through the door, the lock bolt is thrown by pushing the 'lock' button on the key fob or swiping the RFID tab in front on the external RFID reader; • to lock the door from the inside, an RF fob lock button or a switch is used. This could be: o a separate switch (hard wired) on the door frame or a wall near to the door; o a separate switch located on the door that activates an RF transmitter; o by using the 'lock' signal from the RF transmitter built into the door handle - an upward (as opposed to the downward opening action) action is used to lock the door; o by using a push button switch to activate the 'lock' signal from the RF transmitter built into the door handle; and o a button on the control panel (e.g. the spare 'alarm' button) that is used to lock the door.

• if the door is opened using the frame handle, or the stop knob on the frame handle is disengaged, then the lock bolt is thrown by activating a switch. This could be: o a separate switch (hard wired) on the door frame or a wall near to the door; o a separate switch located on the door that activates an RF transmitter; o a separate RF transmitter built into the door handle - an upward (as opposed to the downward opening action) action is used to lock the door; o a separate RF transmitter built into the door handle and is activated by a push button switch; and o a button on the control panel (e.g. the spare 'alarm' button) that is used to lock the door.

• red external LED confirms door is in locked state;

• if not re- locked or door opened, auto lock function after 20 seconds (can be user set e.g. 5, 10,15, 20 seconds or set to off, i.e. no autolock); and

• after 20 seconds of being locked the LED reverts to white.

Leaving the house:

• internal control box shows red LED for locked and display reads locked;

• leave house using door handle only (1 handed exit). Turning the handle sends an RF signal to the RF reader;

• the lock bolt is withdrawn;

• solenoids unlock; • the internal control panel shows green LED;

• external LED remains white;

• if the door is left unopened after turning the handle, the door will re-lock itself after

5 seconds to reduce the security risk of accidentally unlocking the door;

• the control panel LED is green while door is unlocked and open;

• the display reads 'open';

• the door bolt will be deadlocked immediately upon closure; • solenoids re-lock once door is shut;

• the internal (and external) LED will return to red once the door is shut;

• the display reads locked; and

• the external LED will be red for 20 seconds to confirm that the door is in a locked state, and then will turn to dimmed white after this interval.

Putting the door in latched mode:

• to put the door on latch, the frame handle is pulled down and the stop-knob is deployed (double action sequence); • door bolt is withdrawn; and

• solenoids unlock.

Without operating the stop-knob, the frame handle returns on a spring to its normal position:

• inner LED status light shows green to show door is unlocked;

• the display reads 'latched open';

• the outer LED turns green and remains green for 20 seconds before turning to dim white (this reduces the risk of potential intruders knowing that a door is in a latched state);

• deactivating the stop-knob allows the bolt to deadlock if the door is closed;

• the solenoids re-lock as soon as the door is closed;

• display reads locked;

• LEDs turn red, with external LED changing to white after 20 seconds;

Exiting the building during system failure:

The occupant will try to use the door handle to exit the building through the door. The door handle will be inactive due to either no RF signal being transmitted from it or a power/system/firmware failure in the control panel or main box:

• frame handle is turned to withdraw the lock bolt; and

• non-active main handle is used to pull door open in steady or turned position.

The following describes the operation of the security locking system without the relock function engaged.

Using the RFID Tab for entry:

• dimmed white external LED is visible in the external hardware plate

The RFID tab is placed in front of RFID reader plate:

• lock bolt withdrawn;

• solenoids unlock;

• sounder sounds 2 short beeps; • green external LED (reverts to white after 20 seconds);

• control panel LCD reads 'unlocked'; and

• control panel shows green LED.

Push the door open; push door shut - status remain the same - the door is unlocked press 'lock' button on RF fob or activate internal lock switch:

• lock bolt is thrown to lock door;

• solenoids lock;

• sounder sounds 1 long beep; • red external LED (reverts to white after 20 seconds);

• control panel LCD reads 'locked'; and

• Control Panel shows red LED.

Using the RF Fob for entry:

• dimmed white external LED is visible in the external hardware plate.

The RF fob 'unlock' button is pressed:

• lock bolt withdrawn;

• solenoids unlock; • sounder sounds 2 short beeps;

• green external LED (reverts to white after 20 seconds);

• control panel LCD reads 'unlocked'; and

• control Panel shows green LED.

Push door open; push door shut - status remain the same - the door is unlocked.

Press 'lock' button on the RF fob or activate internal lock switch/button:

• lock bolt is thrown to lock door; • solenoids lock;

• sounder sounds 1 long beep;

• red external LED (reverts to white after 20 seconds);

• control panel LCD reads 'locked'; and

• control panel shows red LED.

Unlock without entry or opening the door:

• dimmed white external LED is visible in the external hardware plate

The door is unlocked by either the RFID tab or the RF fob:

• green external LED shows when unlocked

Without opening the door, use the RFID tab or the RF fob again to lock:

• red external LED confirms door is in locked state; • if not re-locked or door opened, auto lock function after 20 seconds (can be user set e.g. 5, 10,15, 20 seconds or set to off i.e. no autolock); and

• after 20 seconds of being locked the external LED reverts to white.

Leaving the house:

• internal control box shows red LED for locked and display reads locked;

• leave house using Door handle only (1 handed exit). Turning the handle sends an RF signal to the RF reader;

• the lock bolt is withdrawn; • solenoids unlock;

• the internal control panel LED turns green; and

• external LED remains white.

If the door is left unopened after turning the handle, the door will re-lock itself after 5 seconds to reduce the security risk of accidentally unlocking the door:

• the control panel LED is green while door is unlocked and open; and

• the display will read 'open'.

Pull the door open and exit; pull door shut - status remains the same - the door is unlocked.

Press 'lock' button on the RF fob or swipe the RFID tag over external the RFID reader:

• the door Bolt will deadlock; • solenoids re-lock;

• the internal (and external) LED will return to red once the door is shut;

• the display will read locked; and

• the external LED will be red for 20 seconds to confirm that the door is in a locked state, and then will turn to white after this interval.

Putting the door in latched mode:

• to put the door on latch, the frame handle is pulled down and the stop-knob is deployed (double action sequence);

• door bolt is withdrawn; and

• solenoids unlock.

Without operating the stop-knob, the frame handle returns on spring to its normal position:

• inner LED status light turns green to show door is unlocked;

• the display reads 'latched open'; • the outer LED turns green and remains green for 20 seconds before turning to dim white (this reduces the risk of potential intruders knowing that a door is in a latched state);

• deactivating the stop-knob allows the bolt to deadlock if the door is closed;

• the solenoids re-lock as soon as the door is closed; • display reads 'locked'; and

• LEDs turn red, with external LED changing to white after 20 seconds.

Exiting during system failure

The occupant will try to use the door handle to exit the building through the door. The door handle will be inactive due to either no RF signal being transmitted from it or a power/system/firmware failure in the control panel or main box.

• frame handle is turned to withdraw the lock bolt; and • non- active main handle is used to pull door open in steady or turned position.

The following describes the lock system failure operation functionality.

The potential for system failure arises from a power failure in any one of the powered elements (active RP fob, internal RP door handle, main box, control panel etc.) or from electronic or firmware failure:

• the internal frame handle provides a direct mechanical link to the door lock bolt mechanism and ensures that any occupant can exit the door during system failure;

• the Solenoid bolt(s) will fail to safe in a complete system failure;

• the main box incorporates a battery back-up that will allow the system to operate as normal for a limited time (1 week) in the event of a power failure. Should the power be restored, the system will revert to normal operation and the back-up battery will recharge to full capacity; and

• during battery powered operation due to main power failure, the solenoids will operate for a limited duration only due to their power demands. After this duration, power is cut to the solenoids and their bolts are withdrawn (unlocked). The door is still locked by the main door bolt.

Total System Failure:

• exit from property - frame handle is rotated to mechanically withdraw the door bolt.

The door handle is pulled to open the door;

• locking property - a physical key is used to lock the door (through the hidden keyhole) by mechanically throwing the bolt into the striking plate (keep); and

• entry of property - a physical key is used to unlock the door (through the hidden keyhole) by mechanically withdrawing the bolt into the lock case.

Door handle battery dead:

• the door is opened by rotating the frame handle to allow the bolt to collapse. Solenoid(s) withdraw. Pull door handle to open the door.

Active RF fob battery dead:

• The door is unlocked or locked using the passive RFID tab integrated into the active fob housing. A physical key can also be used to unlock the house.

Additional security features include: two of the three buttons on the control panel that may be used to increase security. Each operates in a toggle manner, i.e. press once to activate, press again to de-activate:

• night guard - temporarily disable all the RFID and fob (i.e. electronic entry) devices (except for 'master' RF fobs and 'master' RFID tabs which are set as such by main keyholder) for additional security when in the premises. Physical keys will still work; and

• handle guard - temporarily disable the inner door handle so that children, sleepwalkers, dogs etc. cannot open the door one handed (or pawed or mouthed).

Signals read by RFID reader and RF receiver:

• signal W - all active (i.e. not suspended) RF fobs and RFID tabs including door handle can unlock the door; • signal Y - all active RF fobs and RFID tabs except door handle can unlock the door; and

• signal Z - only master RF fobs and master RFID tabs can open the door - door handle, non master RF fobs and non master RFID tabs will not open the door.

The parameters of the locking system may be determined and adjusted by a user via the main control panel. The system is configured such that only the main key holder has authorisation to access the settings and to adjust the various parameters. The main menu access to system setup and key management is controlled by a pin code:

• sound confirmation on (and volume levels) or off separately for internal and external sounders;

• autolock - door automatically locks after a specified time (5, 10, 15, 20 seconds) if

not opened after being unlocked by a signal. Can be set to off so that the door does not lock after receiving a signal to unlock;

• time and date can be set; and

• PIN can be changed.

The present system is compatible for use via a remote central control such as a networked computer, the internet or portable handheld device such (mobile phone). In particular, the present system is capable of receiving and transmitting data from a remote computer or portable device to allow both remote operation of the various electromechanical components and to activate and deactivate the locking mechanism on one or more doors/windows of the building. Also, the security system configuration may be controlled remotely such as the system setup and operational parameters.
