The MB-240 is a photo-thermal conventional smoke detector designed to operate with the MB-200 Series fire alarm system.
The MB-240 photo-thermal smoke sensor uses combined photo and thermal signals to respond quickly to fast clean burning and smoldering fires. The sensor’s thermal enhancement provides a higher alarm threshold and improves rejection of many common causes of nuisance alarm. The sensor will also raise an alarm at temperatures
exceeding 135 F.
The detector operates on a low current, and is easy to maintain owing to its drift compensation and removable detector chamber for cleaning. Its advanced LED design offers 360° views.
