Today, all buildings are required to have some type of fire prevention system in place to ensure the safety of the occupants of the building in case of a fire. These fire prevention systems must be capable of detecting a fire inside the building until it extends. This task is assigned to the devices of fire alarm, located in various parts of the building. Fire alarm devices are appliances designed to locate signs of fire inside the building. Fire alarm devices tell the system that sends an alarm if you recognize at least two of the following signs of fire in the same location: * smoke * increase in air temperature * important amount of these three signs of fire carbon monoxide are detected by three fire alarm devices. The smoke detector determined the presence of smoke in an area. Thermostat sensor identifies changes in the temperature of the air.
Finally, the detector of carbon monoxide, the system warns of the presence of poisonous gas. If two of these signals are detected by fire alarm devices, the area in question must be tested immediately to confirm if there really is a fire. Then, proper fire protocols should be followed in an orderly manner, using fire extinguishers of fire, evacuation of occupants of the building, if it is necessary. Apart from the detectors of the indicators that fire in the building, fire alarm devices are also used to monitor the status of implementation of many other components of the fire alarm system. For example, there are two fire alarm devices installed in the irrigation system, whose task is to track the execution of the irrigation system. These two fire alarm devices are valve position switch, which shows if irrigation valves are open or closed, and switch water flow, that shows if there is enough in the sprinkler system water. Fire alarm devices they can also help keep your system of fire prevention activated in case of failure of the automatic system. During a real fire, if something goes wrong with the connections from the main control, alarm devices of fire, such as the stations of lever allows you to activate the alarms and strobe lights that help maintain the orderly evacuation of the building. These lever stations tend to be located near the building emergency exits. Original author and source of the article.
