Nowadays, all buildings are required to have some sort of fire prevention system in place to ensure the safety of the building's occupants in the event of a fire. These fire prevention systems must be able to detect a fire within the building before it spreads. This task is assigned to the fire alarm devices, which are situated in several parts of the building.

fire alarm devices are gadgets designed to locate signs of fire within the building. The fire alarm devices tell the system to send out an alarm if it recognizes at least two of the following signs of fire in the same location:

* presence of smoke
* increased air temperature
* significant amount of carbon monoxide

These three signs of fire are detected by three different fire alarm devices. The smoke detector determines the presence of smoke in an area. The thermostat detector identifies the changes in air temperature. Finally, the carbon monoxide detector notifies the system of a presence of the poisonous gas.

If any two of these signs are detected by the fire alarm devices, the area in question must be checked right away to confirm if there is really a fire. Then the proper fire protocols have to be followed in an orderly fashion, from using fire extinguishers, to the evacuation of the occupants of the building, if necessary.

Other than being detectors of fire indicators in the building, fire alarm devices are also used to monitor the performance status of many other components of the fire alarm system.

For example, there are two fire alarm devices installed within the sprinkler system, whose task is to keep track of the performance of the sprinkler system. These two fire alarm devices are the valve position switch, which shows whether the sprinkler valves are open or shut down, and the water flow switch, which shows if there is enough water supply in the sprinkler system.

fire alarm devices can also help keep your fire prevention system activated during malfunctions of the automatic system. During an actual fire, if ever anything goes wrong with the connections from the main control, fire alarm devices such as the pull stations will allow you to activate alarms and strobe lights that will help keep the evacuation from the building orderly. These pull stations are normally located near the fire exits of the building.
