4-Wire Smoke & Heat Detector with Relay Output FT143

General Description

   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 security alarm control 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. The detector 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.The detector combine a photo electronic sensing chamber and a temperature heat detector.
