Fire Alarm & Fighting Systems
Fire alarms are among the most vital components of your building’s fire protection system. Having a working, well-maintained fire alarm system is crucial both for keeping your building safe from fires and for keeping it compliant with legal requirements. As with most things in your building, your fire alarm system’s future performance is largely dependent on how well it’s initially installed and how frequently it is inspected and tested.

Conventional & Addressable Fire Alarm Systems
Both types of alarm link devices (such as call points and smoke detectors) to a main control panel. The main difference between the two is that with addressable fire alarm systems, you can pinpoint exactly which device has been activated.
With a conventional system, there is no way of pinpointing the exact location of the fire. However, by wiring your building into different zones, you can get a general idea of where the fire is. For instance, if you have two floors, you could wire the first as ‘zone 1’ and the second as zone 2. So if a fire occurs in zone 1, you know that the fire is somewhere on the first floor.
With a conventional alarm, each device will be connected to the control panel via its own wire, rather than a shared one. One end of the wire will be touching the device, and another touching the control panel.
Addressable alarm systems
Every device connected to the addressable system has its own unique address. When a fire is detected, the device’s address shows up on the main control panel, telling you exactly which device has been activated. This will enable you to find the exact location of a fire and extinguish them quickly.
Addressable alarm systems connect devices using a loop. This is where one wire connects all devices to the control panel. Both ends of the wire loop connect to the control panel.
