The ANWETECH H204 is a 2-wire heat detector designed to detect abnormal temperature rise in indoor environments. Based on high-precision heat sensing technology, the detector provides stable and reliable fire detection performance for applications where heat detection is preferred over smoke detection.
With advanced SMT production technology and optimized internal structure, the H204 offers strong anti-dust capability, improved resistance to electromagnetic interference and reduced false alarms. Its compact ceiling-mounted design makes it suitable for houses, villas, office buildings, shopping malls, factories, warehouses and other indoor applications.
The H204 is ideal for conventional fire alarm systems requiring a 2-wire heat detector with low standby current, stable operation and simple installation.
