Dual chamber ionization smoke detector senses both visible and invisible products of combustion and is designed for 2-wire and 4-wire system operation. The 360o smoke entry characteristic permits maximum smoke response from any direction.
To assure that the detector is functioning, an LED pulses approximately every 4 seconds to allow for visual supervision of the detector. Under alarm condition, the LED lights constantly at full brilliance. An optional base is available to provide a remote LED function.
