Description
NOHMI BOSAI
TYPE: FDS551B
IONIZATION DETECTOR WITH BASE
The Nohmi Bosai FDS551B is an ionization detector supplied with its base, serving as a detection point in a shipboard fire alarm system. Its job is to raise an alarm at the fire control panel when it responds to a fire condition in the space it covers, giving the crew early warning before a fire spreads. The detector and base are offered together, so the complete point is available as one set. Condition is New Open Box. Ionization detectors of this kind are typically placed in enclosed spaces where early detection of a developing fire matters.
