The Tyco 850H (516.850.053) is a digital addressable heat detector designed for Tyco MX marine fire detection systems. It measures temperature using a low-thermal-mass thermistor and supports both fixed-temperature and rate-of-rise detection, making it suitable for areas where smoke detectors are unsuitable.
