Product Details
Four wire 12V relay output wired smoke detector
The detectors are photo-electronic detector uses a state of-the-artoptical sensing chamber. This detector is designed to provide open area protection and to be used with most conventional fire alarm panel. 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
