Conventional heat detector

Product Overview

  OT303 Heat Detector is designed to timely and automatically detect and judge on-site fire factors. With a precise NTC resistor, it can sense the environment temperature. It also can automatically realize contamination compensation of non –fire factors (like temperature, humidity, dust, etc.) and effectively keep detector in a steady status.
