The Heater Base is designed to protect detectors from damage caused by cold environmental conditions, such as icing or condensation. It raises the chamber temperature of the detector by approximately 10°C, ensuring reliable performance in harsh climates. Compatible with Apollo addressable detectors (45681-219) and Orbis detectors (ORB-HB00020-APO), it helps prevent moisture-related damage, maintaining the detectors' functionality in low temperatures. For added protection, it is recommended to use the heater base with a waterproof base cover (45681-519) or deckhead mounting box (29600-196) to reduce moisture ingress. Ideal for use in cold climates where environmental conditions could affect detector operation, the Heater Base ensures optimal performance of fire alarm systems, limiting the risks of functionality loss in extreme conditions.
