Standalone Smoke & Heat Detector AW-SST606D

Standalone Smoke & Heat Detector is a combined detector that uses the heat runner with the best heat transfer sensitivity and the most advanced optical sensing chamber. It is designed to provide open area protection without wiring. The red LED on the detector provides a local 360°visible alarm indication. They flash once every minute, indicating that the power is on and the detector is working. When an alarm occurs, the red LED is on, until the smoke concentration and temperature are lower than the alarm threshold.
