The detector is a photodetector that uses the most advanced optical sensing chamber. The detector is designed to provide open area protection.
A bi-color LED on each detector provides a local 360° visible alarm indication. They flash once every minute to indicate that power is on and the detector is working properly. The red LED flashes when the alarm occurs. When there is a fault condition indicating that the detector sensitivity is outside the listed limits or the battery is low, the yellow LED will flash. The alarm can be reset by pressing the button or when the fire alarm is not collected for a long time.
