Two LEDs on each detector provide local 360° visible alarm indication. They flash every six 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. 
The detector that initiated the alarm condition will have its red LED and relays latched until reset by panel.
Heat detector and smoke & heat detector combine a photo electronic sensing chamber and a temperature heat detector.
