Addressable Fire Alarm Systems

We specialize in designing conventional as well as addressable type of Fire Alarm & Detection System for small / medium / large commercial / industrial establishments including high rise buildings, hotel, hospitals and corporate business houses.

Addressable fire alarm systems offer benefits in speed of detection, identification of the location of a fire and easier maintenance. Addressable fire alarm systems also offer tolerance to faults in the system wiring, which allows a single pair of wires to be used to connect up to 200 devices to the system, allowing cost savings in the wiring of large systems. In larger installations, the benefits of improved maintenance and reduced cabling cost are overwhelming. The price difference between Addressable systems and conventional systems has narrowed to such an extent that even for small installations, the use of an Addressable fire alarm system should be considered.

Analogue Addressable Fire Alarm Systems differ from conventional 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 larger 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 system may contain one or more loops depending upon the size of the system and design requirements. The Fire Control Panel 'communicates' with each detector individually and receives a status report, i.e. 'Healthy', 'In Alarm' 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 and for this reason 'zoning' of the system is not necessary, although it may be done for convenience.

Addressable detectors are, in themselves, 'intelligent' devices which are capable of reporting far more than just fire or fault conditions; 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 signalling taking place.
