Analogue-addressable fire alarm systems provides specific details on individual fire detector locations.

Addressable or “intelligent” fire alarm systems are designed for larger building and are capable of being networked systems with adjoining addressable fire alarm systems.

In addressable systems, different devices are wired in one or more single loops of cable around the premises, requiring less cabling than conventional systems, with each detector or call point having its own unique address.

The addressable control panel receives information and status reports from each device and indicates its exact location if there is a fire, fault, smoke, heat, or contamination to the user. Also the control panel carries out a constant polling routine in which each device is interrogated in a programmed sequence. Each Detector responds with a status report ‘Healthy’, ‘Pre-Alarm’ ‘In Alarm’ or ‘In Fault’.

The analogue part of these systems enables the detectors to monitor the contamination or heat level in each fire detector. The analogue information constantly monitors the temperature or contamination of the air flow through the detectors.
