• The wireless systems use radio frequency when transmitting its signal towards the control panel form its fire detectors. There are thermistors in heat detectors for heat sensing. Gas is traced in carbon-monoxide detectors with, electro-chemical, bio-mimetic, and integrated chemical cells. Smoke detectors always use ionization in smoke detecting whereas combined detectors always use various detection mechanisms.
• The panel of fire alarm activates sounders or flashers, activates the sprinklers, or they may make calls to the occupants or authorities.
