The Tyco 711H (Part No. 516.900.103) is a conventional rate-of-rise heat detector designed for reliable fire detection in marine and industrial environments. It uses both rate-of-rise and fixed-temperature sensing, providing an additional response when temperature rises rapidly while retaining fixed-temperature protection for slowly developing fires. The detector is classified as A1R under EN 54-5 and is designed for conventional two-wire detection systems. It is also suitable as a replacement for compatible 600 Series detectors.
