Product Overview The detector is a combined smoke and heat detector with photoelectronic sensor and heat thermistor together.This detector is designed to provide open area protection and to be used with most conventional fire alarm control panel. Two LEDs on each detector provide local 360° visible alarm indication. They flash every 3~5 seconds indicating that power is applied and the detector is working properly. The LEDs latch on in alarm. LEDs will be off when a trouble condition exists indicating that the detector sensitivity is outside the listed limit. The detector can be reset only by a momentary power interruption.
