Gemini GEM-HEAT

The GEM-HEAT wireless heat detector tackles one of the key blind spots in fire detection: areas where smoke detectors may not respond reliably (such as kitchens, garages, boiler rooms or dusty/steamy environments). By combining a fixed-temperature trigger (135 °F/57 °C) and a rate-of-rise trigger, the unit detects both sustained overheating and sudden temperature spikes. sdepot.com+2Anixter+2 Its wireless design uses crystal-controlled RF technology for high reliability, making it easy to integrate into existing wireless security loops without complex wiring. napcosecurity.com+1 The included replaceable lithium 3 V battery offers years of dependable service and sends low-battery signals automatically, reducing maintenance risk. ADI Global Distribution Compared to many conventional detectors that only monitor smoke or require hard-wiring, GEM-HEAT provides a flexible, wireless solution that’s ideal for retrofit or new-build settings where wiring is challenging. Whether for a home automation/alarms setup, light commercial property or fire-protection upgrade, it ensures temperature-based alerting that complements smoke detection and enhances occupant safety.
