Fire Alarms Smoke Alarms
Smoke Alarms
A single sensor smoke alarm is either a photoelectric or ionization detection unit that responds when it sees smoke. Newer conventional detectors offer environmental compensation with differentiating sensing that makes them immune to sensitivity drift, a common cause of false alarms. Devices are available for both hard-wired systems and analog technology.
