Analogue Addressable
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.
