System temperature detector

Constant temperature heat detector manual

Product introduction

This heat detector provides consistent temperature detection and is suitable for any home or commercial applications. The detector consists of an externally mounted thermistor with a specially designed cover that protects the thermistor while allowing maximum airflow. The thermistor reads the temperature from the air it enters and sends a signal representing the temperature to the control IC. If the temperature reaches or exceeds the trip point, the detector is triggered. The status LED lights up red and emits an alarm signal. The detector is an ideal unit for detecting rapid fire developments in homes, shops, hotels, restaurants, offices, schools, banks, libraries, etc.
