The Single Channel Photoelectric Smoke Detector from Advanced Aircraft Extinguishers, Ltd is a reliable, high-quality detector for smoke in aircraft lavatories, equipment areas, etc.

Features one bi-colored LED for indication of status. In a normal standby condition, the LED flashes Green every 3 seconds. When the detector senses that its sensitivity has drifted outside the UL listed sensitivity window, the LED will flash Red every 3 seconds, indicating the detector needs to be cleaned. When the detector senses smoke and goes into alarm, the status LED latches solid on RED.
