Technical field
The present invention relates to field of fire fighting equipment more particularly to a kind of fire protection alarm systems.
Background technique
Automatic fire alarm system or fire detection alarm system, the one kind for being mounted in building or other places are automatic
Fire-fighting system device.The system is mainly made of trigger device, fire alarm control unit and power supply, which can be at the beginning of fire
Phase, the physical quantitys such as smog, heat that burning is generated are passed fire behavior information by field erected detector (i.e. trigger unit)
It is defeated to arrive fire alarm control unit, to show the position of fire generation, the time that record fire occurs, so that related personnel's energy
Enough adopt an effective measure in time controls and stamps out a fire.
From the point of view of development process, automatic fire alarm system is broadly divided into three phases:
