SF-211 24V 2wire Fire Alarm System Smoke Detector
Smoke&Heat Detector work perfectly with all conventional intelligent fire control panels
This Conventional Multi-detector uses an intelligent optical sensing chamber and a thermal sensor at the same time to detect smoke.
This detector is designed to provide open area protection and to be used with most conventional fire alarm control panels where it can work from 9Volts to 32V D.C.
It has two LEDS on each detector to provide a local 360° viewing alarm indication.
It flashes every five 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 occurs indicating that the detector sensitivity is outside the listed limit. The alarm can be reset only by a momentary power interruption.
