4 Wire Conventional Smoke Detector AW-CSD501-4W
The detectors are photo-electronic detector uses a state-of-the-art optical sensing chamber. This detector is designed to provide open area protection and to be used with most security alarm control panel.
Two LEDs on each detector provide a 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 the panel.
Heat detector and smoke & heat detector combine a photoelectronic sensing chamber and a temperature heat detector.
