Analogue Addressable Systems
Intelligent fire alarms systems
Analogue addressable fire alarms provide simple, effective engineering without the need for custom-designed equipment.
Intelligent
Intelligent or analogue addressable devices are individually identified with an address (number) on a loop of wiring.
The control panel communicates with each device in turn and each device reports back an analogue value based upon how much smoke or heat is present.
The control panel, not the detectors, then makes all the decisions with regard to sounding the alarms.
With an intelligent system, if a fire is detected, its position can be pin-pointed because each device has its own unique address which means its location can be found precisely.
What is a conventional system and what is an intelligent system?
In conventional systems, detectors are hard wired into a circuit or zone. They signal fire or fault conditions to a control panel by changing from a high to low impedence. The panel detects this impedance change by current monitoring and identifies the zone. Individual detectors cannot be identified.
Intelligent systems incorporate hard wired loops and each device has a unique address code. The control panel carries out a polling routine in which each device is interrogated in a programmed sequence. Devices respond with a status report which, as confirmation that the correct device is responding, includes its own address code.
Intelligent systems give advance warning of a developing hazard and pinpoint the individual device raising the alarm. It is possible to follow the spread or progress of a fire as individual detectors report conditions in their area and this could allow a phased evacuation and precise direction of fire-fighting teams.
