Napco GEMC-WL-HEAT-2 Gemini Series Commercial Wireless Heat

Protect commercial properties with fast, reliable heat detection from Napco Security Technologies. The GEMC-WL-HEAT-2 wireless commercial heat detector combines a 135°F (57°C) fixed temperature threshold with rate-of-rise sensing to detect rapid temperature increases while reducing nuisance alarms — delivering dependable fire detection where smoke detectors may be unsuitable. As a Gemini series heat detector, it communicates via 319.5 MHz to Gemini wireless receivers, enabling flexible installation and seamless integration into existing security and monitoring platforms. Powered by a long-life 3V lithium battery, the unit provides supervised operation, periodic test signals, and low-battery annunciation so building managers and integrators maintain continuous protection without frequent servicing. Designed for commercial security, surveillance and life-safety applications, the GEMC-WL-HEAT-2 is ideal for boiler rooms, mechanical spaces, attics, and renovation projects that require minimal wiring.
