Fire detectors sense one or more of the products or phenomena resulting from fire, such as smoke, heat, infrared and/or ultraviolet light radiation, or gas. In dwellings, smoke detectors are often stand-alone devices. In non-domestic buildings, fire detection will typically take the form of a fire alarm system, incorporating one or more of the following automatic devices:
- Photoelectric smoke detector
- Photoelectric heat detector
- Combination of Photoelectric smoke detector and heat detector
- Pull Station/call point/Break Glass
- Alarm Bell/Sound/Stober
- Isolator Module
- Monitor Module
- Fire Alarm Panel Board
