Fire detection and protection system description?

A system which is networked with extinguishing and detection devices to ensure that the danger of fire is low. Smoke/Heat detectors, sirens, bells, sounders and call points are in place to detect any fire and alert you if there is the need to evacuate. A person can manually activate the call point if they discover a fire. When the fire alarm sounds, extinguishing apperatus such as sprinklers, CO2 gas release will activate, in order to quickly put the fire to a halt.
