Abstract:
Closure system remotely controllable by transmitter signals (I) for one or more locks (L) of one or more openings (T), having a portable transmitter (S) as key (S) for radiating the transmitter signals (I), namely the UNLOCK transmitter signals (I) which (I) initiate the unlocking (Z) of the relevant lock or locks (L), and/or the LOCK transmitter signals (I) which initiate the locking (Z) of these locks (L), having a receiver (E) which (E), if it is within range (W) of the transmitter (S), triggers a control signal (Z) after the reception of the transmitter signals (I), and having a locking element (B) which can be controlled by the control signal (Z), by means of which (B) the relevant lock (L) can be locked and/or unlocked. The receiver (E) monitors a parameter of at least individual ones of the received transmitter signals (I), such as their (I) power or field strength, and adjusts-at least from time to time-the range (W), namely the sensitivity of the receiver (E) and/or the transmitting power of the transmitter (S) in accordance with the parameter monitored.
