Fire Alarm SystemsAnalogue Addressable Fire Alarm SystemsWith a conventional fire alarm system, each zone must be wired using a separate circuit, to enable the source of a fire alarm to be identified. Furthermore, in the event of a fire alarm being triggered, the panel can only identify which zone contains the triggered device, it is then necessary to manually search the affected zone to discover the actual cause of the alarm. An analogue addressable system overcomes these limitations. Each fire detecting sensor or call point is electronically coded with a unique 'address'. The control panel is then able to conduct two way communication with any of the addressable devices connected to the system by using the unique address number to define which device it wishes to communicate with. The panel can ascertain whether each device is functioning correctly and also discover the amount of smoke or heat that the device is currently sensing. This technology allows the panel to make 'intelligent' decisions as to the appropriate action to take based on the information it receives from the individual sensors. This has many advantages, for example very slow build up of apparant smoke density seen by a sensor can cause a warning or pre alarm condition to be triggered by the alarm panel prior to the situation becoming serious enough to warrant a full alarm. |
