The device is intelligent sensors that utilize a state-of-the-art thermistor sensing circuit for fast response. 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 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 alarm can be reset only by a momentary power interruption.
