Smoke and Heat Detector FT-143 Relay output 4-wire
The detector is 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 sides provide local 360 degree visible alarm indication. 
The LEDs show the detector working status and sensitivity. 
The alarm can be reset only by a momentary power interruption. 
Red LED indication and relays latched when alarm. It combines a photo electronic 
sensing chamber and a temperature heat detector.
