The 3 Main Types Of Fire Alarm System

Conventional Fire Alarms


These fire detection systems divide your premises into zones. In the event of an alert – perhaps triggered automatically by a smoke detector or manually by a ‘break glass’ alarm – wiring linked to an LED control panel will identify the zone. But it won’t indicate the precise area.

Addressable Fire Alarms

Here, each individual device, such as a smoke or heat detector, has its own unique electronic address. If one activates, the fire alarm system control panel tells you precisely where the problem lies.

Wireless Fire Alarms

A fire detection system which uses a secure wireless link between the sensor and the control panel. Most will offer sounders, beacons and call points. These are a great option if you don’t want lots of cable on your premises.

So Which Type Of Fire Alarm System Is Right For Your Business?


Unfortunately there’s no one answer. It depends on the size and layout of your premises, the budget available and, crucially, the competence of the installer.


  • A conventional fire alarm system may not be as sophisticated as an addressable fire detection system. But the fact that it’s simpler doesn’t necessarily make it less effective or unreliable. For some businesses a simple, less costly, conventional solution will be the best option.

  • Addressable fire alarm systems are more accurate at pinpointing the seat of a fire and can reduce the incidence of false alarms (a profit-swallowing nuisance) by constantly sampling air for contamination. They’re more complex and you should certainly make sure your installer is properly qualified. But, correctly fitted, they can be cost effective and very reliable.

  • Wireless fire alarm systems are now well-established and are an excellent solution for business wanting to avoid the cost and disruption of installing cabling everywhere. Wireless may especially appeal to schools, hospitals and shops or companies based in heritage buildings where the fabric and décor has to be carefully preserved.
