2.1.1 Use
Multi-sensor smoke detector FDOOT221
Multi-sensor smoke detector consisting of:
● Point detector with additional heat sensors
● Detector dust cap to protect the point detector during the construction phase
Function
● Functions according to the scattered light principle with two sensors: Optical
forward and backward scattering
● Opto-electronic measuring chamber: Obstructs disruptive extraneous light
but can be relied upon to detect both light and dark smoke particles
● Two additional heat sensors increase the fire detector's immunity to
deceptive phenomena.
● Selectable detection behavior thanks to different parameter sets
Use
● For early detection of flaming fires of solid and liquid substances as well as
of smoldering fires
● For early and reliable fire detection in an environment with deceptive
phenomena
● Can be used addressed
