ANWETECH AT-H207 is a 4-wire fixed temperature heat detector designed for fire alarm and control systems. It features a high precision heat sensor, relay output, wide DC9–36V operating voltage and stable anti-interference performance for reliable indoor fire detection.
The ANWETECH AT-H207 is a 4-wire heat detector designed to detect high temperature conditions in fire alarm systems. It uses a high precision heat sensor to respond when the ambient temperature reaches the alarm threshold, making it suitable for areas where heat detection is more appropriate than smoke detection.
Built with advanced SMT technology and a durable anti-dust structure, the AT-H207 provides strong environmental adaptability and good resistance to electromagnetic interference. Its ceiling-mounted design is suitable for houses, office buildings, villas, shopping malls, factories and warehouses.
Compared with 2-wire heat detectors, the AT-H207 provides a relay-based output structure, making it suitable for fire alarm systems and control applications that require switching output and flexible integration.
