Wireless multi-criteria detector. 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. Two-way radio communication. Immediate transmission in the event of an alarm, fault or removal. Monitored dual battery for backup. Two-tone LED with 360° visibility. Option of conducting the test with a magnet. IP40 rating. Approved to EN 54-5, EN 54-7 and EN 54-25. Base included.
