Napco GEM-HEAT Wireless Rate / Rise Heat Detector

Protect critical spaces with fast, dependable heat detection — the Napco Security Technologies GEM-HEAT Wireless Rate/Rise Heat Detector is engineered for professional security and fire monitoring. This heat detector combines a 135°F (57°C) fixed-temperature element with rate-of-rise sensing to detect both steady and rapidly increasing heat conditions, reducing the chance of missed or delayed alarms. As a supervised wireless transmitter, GEM-HEAT integrates seamlessly with NAPCO Express and Gemini GEM-RECV Series receivers, sending hourly supervisory tests and low-battery reports so your security team and monitoring center always know device status. The crystal-controlled wireless design delivers consistent transmission performance for surveillance and alarm systems, while the factory-assigned unique ID eliminates the need for coding switches to simplify deployment. Powered by a single 3V lithium battery with up to two years of life, GEM-HEAT lowers maintenance overhead for commercial kitchens, server rooms, warehouses, and other critical environments where smoke detectors are impractical.
