Heat detection sensor FD7110 Nade

A fire alarm system has multiple devices that work together to detect smoke, fire, carbon monoxide and other emergencies and alert people through audio and visual equipment. These alarms can be automatically activated by smoke detectors and thermal detectors, or can be manually activated with the help of a fire alarm at specific fire alarm activation points. Alarms can be motor bells or beeps mounted on the wall. They can also be loudspeakers through which they can alert and then send a voice message to evacuate the location and to warn indoors not to use elevators.
