A fire alarm system has a 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 automatically from smoke detectors, and heat detectors or may also be activated via manual fire alarm activation devices such as manual call points or pull stations.
Smoke (particulate and aerosol) Heat Light Radiation Fire detection devices are built to detect one or a combination of these components. While all components are necessary for a fire to exist, all components may not exist at a detectable threshold. Detectors will be selected that will detect the elements that may exist in a fire for the ambient conditions that are present. It also should be realized the similar non-fire components might exist in the same ambient conditions, which could cause unfavorable false alarm conditions. Devices used for fire detection include smoke detectors, thermal detectors, flame detectors, fire-gas detectors, and other devices. Smoke detectors sense visible or invisible particles of combustion generated by burning, smoldering, or the incipient stage of combustion. These devices fall into two categories -- photoelectric and ionization. Thermal detectors sense the high temperature or the temperature rise caused by a fire. Flame detectors sense the radiation produced by a fire.
