Bosch RFHT-A Wireless Heat Detector

Protect people and property with fast, reliable heat detection designed for living areas and challenging environments. The Bosch RFHT-A wireless heat detector combines fixed-temperature and rate-of-rise sensors to reliably detect both sustained high temperatures and rapid temperature increases caused by fire — reducing false alarms while improving response times. As part of Bosch’s RADION Life Safety portfolio, this heat detector offers long-range RF communication to compatible receivers and G/B series control panels, plus up to 10 years of battery life to cut maintenance and lifecycle costs. IP-class indoor construction and an operating range of 39-131°F make it suitable for kitchens, garages and other dry indoor spaces. Built-in audible signaling and an LED indicator give immediate onsite alerts, while supervisory notifications for battery, tamper and sensor health support proactive system monitoring. Ideal for commercial and multi-family residential security and life-safety systems, the RFHT-A integrates into modern fire monitoring and surveillance strategies for comprehensive protection.
