The Tyco 711H (516.900.103) is a high-performance conventional heat detector specifically engineered for demanding marine environments. As part of the 700 series, it provides reliable fire detection by utilizing a dual-sensing mechanism that responds to both rapid increases in temperature (Rate-of-Rise) and a fixed temperature threshold of 57°C (Class A1R). Its robust design ensures durability and low maintenance, making it an ideal choice for areas like galleys, engine rooms, and boiler rooms where smoke detectors may be unsuitable. The 711H is fully approved for marine use and is compatible with Tyco’s MZX and MINERVA T2000 conventional fire alarm control panels, ensuring seamless integration into existing or new fire safety systems.
