In an addressable fire alarm system, all the devices such as detectors, call points and alarm bells are connected in a loop system to the fire addressable control panel and each device has an address (to tell about their location). This way, it is very easy to find the exact location of the device which has been triggered in the connected circuitry.
The basic idea behind the loop system is that in case of short circuit fault, only a small portion of the system affected while the rest will work properly with the help of isolation module connected in the loop. In a single loop, up to 99 devices may be connected and can be extended up to 3.3 km depends on the ability of fire control panel system.
The main purpose of addressable fire system is same as conventional fire system expect the wiring connection and DIP (Dual In-Line Package) switches for an address or a set of address showing the exact location of triggered component on main addressable fire control panel screen. Addressable is most accurate but costly as compared to conventional system while both are not smart as compared to intelligent fire system which show the exact reason behind the triggered device if it is a fault, pre-alarm or fire and extinguish them quickly.
