Analogue Addressable Fire Alarms differ from conventions systems in a number of ways and certainly add more flexibility, intelligence, speed of identification and scope of control. For this reason Analogue Addressable Fire Alarm systems are the natural choice for commercial premises and more complex system requirements.
In an analogue addressable system, detectors are wired in a loop around the building with each detector having its own unique address. The fire alarm system may contain one or more loops depending upon the sizes of the system and design requirements. The Fire Control Panel communicates with each detector individually and receives a status report e.g Healthy, In Alarms or In Fault etc. As each detector has an individual address the fire alarm control panel is able to display/indicate the precise location of the device in question, which obviously helps speed the location of an incident.
Addressable detectors are, in themselves, intelligent devices which are capable of reporting far more than just a fire or fault condition, for example most detectors are able to signal if contamination within the device (dust etc) reaches a pre-set level enabling maintenance to take place prior to problems being experienced. Addressable detectors are also able to provide pre-alarm warnings when smoke/heat levels, reach a pre-set level enabling investigation of the fire to take place prior to a full evacuation alarm and Fire Brigade signaling taking place.
