Smoke Detector Photoelectric
Photo-electric smoke detectors incorporate a pulsing LED located in a chamber within the housing of the detector. The chamber is designed to exclude light from any external source. At an angle to the LED is a photo-diode which normally does not register the column of light emitted by the LED.
Alarm current at 24V: 52mA; Average stand-by current at 9V: 17mA
Ambient temperature : 32 to 100°F ; Max wind continuous: not affected
