ZETA Standalone Heat Detector – ZT-TH5 Thermistor-Based Heat Sensing

The ZETA Standalone Heat Detector (ZT-TH5) is a compact, self-contained fire safety device engineered for residential and small commercial applications. Utilizing advanced electronic thermistor sensing technology, the ZT-TH5 provides reliable heat detection without the need for a fire alarm control panel. This detector is ideal for locations where smoke detection is unsuitable, such as kitchens, boiler rooms, or dusty environments.

Designed for ease of use and long service life, the detector includes a built-in test button, low-battery warning, and a loud alarm sound exceeding 85 dB at 3 meters. Powered by a 9V alkaline battery, the unit is simple to install and maintain. Automatic power disconnection upon removal from the base ensures added safety during maintenance.
