The invention relates to an assembly of an emergency lighting installation and other safety exuipment, the assembly comprising: a plurality of emergency light fittings at relatively small mutual distances, wherein each emergency light fitting is provided with first ICT means which form a node in a wireless ICT network; second ICT means situated at a distance from the emergency lighting installation; and third ICT means configured and suitable for transmitting data between the wireless ICT network and the second ICT means. The invention also relates to a method for monitoring the other safety equipment forming part of such an assembly.

Background of the invention

Known is an emergency lighting installation, arranged in a building or other structure, comprising a number of fittings at specified maximum, relatively small, mutual distances. Emergency lighting serves as signposting and/or lighting when the mains voltage fails, and has its own energy supply, independently of the source with which the normal lighting is powered. Said own energy supply can be centralized or can be decentralized, wherein each fitting is provided with its own battery.

An emergency lighting installation must be inspected for readiness regularly, generally at time intervals of one year. Each fitting is here inspected for proper electrotechnical functioning, this in addition to damage, fouling and degradation. Monitoring the readiness of an emergency lighting installation often entails high costs, It also provides only limited certainty regarding the readiness, i.e. only immediately after an inspection has been carried out.

GB2534901 describes the remote monitoring of an emergency lighting installation, wherein an electrotechnical parameter characteristic of the readiness of a fitting is measured and wirelessly transmitted. Each fitting is provided for this purpose with measuring means for measuring the electrotechnical parameter and ICT means for wirelessly transmitting a measured value. The ICT means of all fittings together form a wireless ICT network. Because fittings in an emergency lighting installation are distributed more or less evenly around a building or structure, at relatively small mutual distances, they form a highly suitable basis for (the nodes in) a wireless ICT network. The ICT means can here be supplied with energy by means of the already present energy supply of the fittings. Maintenance of a fitting can be performed or planned, or a fitting can be replaced, on the basis of the result of an assessment of a measured value of the electrotechnical parameter, wherein the measured value is compared to a required value. The readiness of the emergency lighting installation can thus be monitored remotely, at low cost and with great certainty. Other parameters, such as ambient parameters, can here also be measured and transmitted by means of sensors provided for this purpose. A lot of other safety equipment, such as fire extinguishers, fire hose reels, extinguishing blankets, extinguishing water systems, AEDs and emergency doors, must also be regularly inspected for readiness and proper technical functioning. Monitoring the readiness of the other safety equipment also entails high costs, and once again provides only limited certainty regarding the readiness, namely only immediately after an inspection has been carried out. The present invention now provides a solution for this.

Summary of the invention The invention provides an assembly according to claim 1 and a method according to claim

9. Maintenance of the at least one device can be performed or planned, or the at least one device can be replaced, on the basis of the result of an assessment of a measured value of the at least one parameter, wherein the measured value is compared to a required value. The readiness of the other safety equipment can thus be monitored remotely, at low cost and with great certainty.

Brief description of the drawings

The invention will be further elucidated hereinbelow on the basis of exemplary embodiments. Figure 1 shows schematically a preferred embodiment of an assembly according to the invention. Further elucidation and exemplary embodiments

The assembly (1) shown in figure 1 comprises an emergency lighting installation comprising a number of emergency light fittings (2a-2e), each provided with first ICT means (3a-3e) which form a node in a wireless ICT network (4). All first ICT means (3a-3e) together form (the nodes / access points in) the ICT network (4). Each fitting (2a-2e) is provided with first measuring means (7a-7e) for the purpose of measuring at least a first parameter characteristic of the readiness of the fitting (2a-2e), for instance in respect of the proper functioning of the light source. The assembly (1) also comprises second ICT means (5) at a distance from the emergency lighting installation, and also third ICT means (6), comprising a communication network suitable therefor, for the purpose of transmitting data between the ICT network (4) and the second ICT means (5). In the context of the invention ‘at a distance’ is understood to mean at a considerable distance, a distance of tens of metres to hundreds of kilometres.

According to the invention, the assembly (1) now also comprises other safety equipment, comprising a number of devices (8a-8g), here fire extinguishers. Each device (8a-8g) is provided with second measuring means (10a-10g) for the purpose of measuring at least a second parameter characteristic of the readiness of the device (8a-8g), for instance internal pressure or weight. The assembly (1) also comprises fourth ICT means for receiving data relating to a measured value of the at least one second parameter. Fourth ICT means (9a-9g) are here provided on each device (8a-8g), but can also be situated elsewhere in another embodiment. Data relating to a measured value of the at least one second parameter can be sent to first ICT means (3a-3e) by means of the fourth ICT means.

The first ICT means (3a-3e) here comprise a memory for storing data relating to location, identity and calibration of a fitting (2a-2e) or a device (8a-8g), data relating to a required value of the at least one first parameter or the at least one second parameter, data relating to control of the first measuring means (7a-7e) and the second measuring means (10a-10g) such as desired times of measurement and time intervals between measurements, and data relating to associated ICT procedures, ICT settings and ICT addresses. The second ICT means (5) here comprises a memory (5a) for storing data relating to measured values of the at least one first parameter or the at least one second parameter and the results of assessments thereof.

The first measuring means (7a-7e) and the second measuring means (10a-10g) can here be controlled by means of the first ICT means (3a-3e), and a measured value of the at least one first parameter or the at least one second parameter can be assessed, by comparing the measured value to a required value. By means of the first ICT means (3a-3e) data relating to the result of an assessment can here be sent to the second ICT means (5) by means of the third ICT means (6). Maintenance of a fitting (2a-2e) or device (8a-8g) can be performed or planned, or a fitting (2a-2e) or device (8a-8g) can be replaced, on the basis of the result of an assessment. In other embodiments of an assembly according to the invention, the storing of data, controlling and assessing can also be performed, partially or wholly, by the second ICT means (5).

The other safety equipment, in addition to the emergency lighting installation, can thus also be monitored remotely. It can here possibly also be determined which first ICT means (3a- 3e) have received data relating to a measured value of the at least one second parameter, and the location of a device (8a-8g) can be further determined on the basis thereof. It will be apparent that the invention is not limited to the given exemplary embodiments but that diverse variants and combinations obvious to a skilled person are possible within the scope of the invention.
