Asenware AW-CTD322 2-Wire Conventional Heat Detector

The AW-CTD322 is a 2-wire conventional heat detector operating with two separate thresholds: fixed temperature and rate of temperature rise. In addition to a fixed alarm threshold of 60 °C, it detects a rapid heat increase of 7.1 °C in 5 seconds as an alarm condition; this dual approach makes it preferable in kitchens, boiler rooms, enclosed parking areas, and dusty manufacturing zones where smoke detectors are prone to false alarms. Power supply ranges from 9-28 VDC and connection can be made regardless of polarity; current draw at alarm does not exceed 48 mA at 24 VDC. Including its base, it measures 99.45 mm in diameter and 31.78 mm in height, allowing it to fit directly into standard base openings on existing conventional loops.
