System Sensor Addressable Heat Detector

Key Features

Overview

System Sensor Addressable Heat Detectors use low mass thermistors and microprocessors to provide fast response temperature sensing. 

System Sensor Addressable Heat Detectors can be configured to provide fixed heat detection at either 58°C or 78°C or as a rate-of-rise detector with 58°C threshold and a rate-of-rise of 10°C/minute.

System Sensor detectors are housed in a modern, white enclosure that includes a tri-colour LED that provides 360° visibility and are available with or without single pole short circuit isolation.
