Wireless addressable multi-sensor detector designed for operation with Comelit wireless expansion modules. The detector has 360° visibility LED indication and a built-in buzzer for additional signalling in the event of a fire alarm (can be excluded) and for searching within the system. To prevent unauthorised disassembly or removal, the detector can be locked on at the base. Equipped with an anti-tamper feature to indicate opening. 45RML100 combines the detection modes of a heat detector and an optical smoke detector, and is therefore particularly suited to applications where early fire detection must be ultra-reliable (hotels, museums, etc.). The detector signals the alarm if the smoke or temperature threshold is exceeded. Device enrolling is easy and instant. Communication distance between detector and expander (in open space) over 1000 m. Two-way radio communication with proprietary communication protocol. Batteries (3 x CR123A) with maximum life up to 10 years (depending on usage and settings). Operating temperature -10°C / +55°C. Dimensions (including base) Ø108x82 mm. Material: ABS. IP30 protection rating. Available temperature classes A1/R and 4 different sensitivities programmable via the fire panel menu. Approved to EN 54-5, EN54-7 and EN 54-25.
