FIRE DETECTION AND ALARM

A “fire alarm system” is number of devices working together to detect and warn people through visual and audio appliances when smoke, fire, carbon monoxide or other emergencies are present. These alarms may be activated from smoke detectors, and heat detectors. They may also be activated via manual fire alarm activation devices such as manual call points or pull stations.

 

Their main function is to quickly identify a developing fire and alert building occupants and emergency response personnel before extensive damage occurs. Automatic fire detection systems do this by using electronic sensors to detect the smoke, heat, or flames from a fire and providing an early warning.

 

Addressable Fire Alarm Systems (AFAS)

Conventional Fire Alarm Systems (CFAS)

 

Addressable Fire Alarm System: 

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. 

 

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.
