Addressable Fire Alarm System

Addressable Fire Alarm Systems give you long-term flexibility and allow you to customize your fire alarm system to your exact company requirements

What is Addressable Fire Alarm System?

Addressable Fire Alarm System is advanced safety system designed to detect and communicate precise information about the location and status of fire-related incidents within a building or facility. These systems are instrumental in enhancing the safety of occupants and property by allowing for swift and accurate response to potential fire emergencies.

Addressable systems are the solution for larger installations. The ‘in panel’ computer (which is programmed to the different detectors and call points) will not only show the zone that the fire is in but the actual detectors(s) and call point(s) that have been activated. This means you can find the source of the fire far more quickly, and deal with it before it becomes an uncontrollable blaze.

Cause and effect mapping can also be programmed in to achieve phased evacuation and many other specific requirements. This can be designed and interfaced with the alarm system to activate automatic fire fighting systems, isolate the power supply to specific machinery and much more – the flexibility of addressable fire alarm systems is almost unlimited…


In view of the confusion that often is associated with the different sort of fire alarms, we thought it might be helpful to explain a few things:

No, this is not the case. Although addressable is often preferred, and indeed specified in certain environments, there is nothing wrong with a non-addressable fire alarm system in a smaller building.

No, but manufacturers typically only recommend 20 devices in a zone. If your building needs more than 200 devices on the system you will probably prefer to have an addressable system because of the functionality advantages of an addressable system.

Yes, there is. A non-addressable system will tell you in what zone a device has activated, but you will have to go the physical zone to identify the device in question which limits search distances. An addressable system will tell you the exact device number and location.

Only an addressable system has this capacity. Once a fault has disappeared on a non-addressable system it isn’t possible to see from the panel what the problem was.

As long as the cabling is in good condition, yes. There are some changes that will be needed to be made to the cabling, as it will need to be changed to a loop rather than a zone or by adding extra control equipment. The panel and all the devices will need to be replaced, but often, the sounders and their circuits can remain as they are.

Yes, they are, but not as much as it once was, as technology improves.
