Smoke detector FDO221
Smoke detector consisting of:
● Point detector
● Detector dust cap to protect the point detector during the construction phase
Function
● Functions according to the scattered light principle with one sensor: Optical
forward scattering
● Opto-electronic measuring chamber: Obstructs disruptive extraneous light
but can be relied upon to detect both light and dark smoke particles
● Selectable detection behavior thanks to different parameter sets
Use
● For early detection of flaming fires as well as smoldering fires
● Can be used addressed
Heat detector FDT221
Heat detector consisting of:
● Point detector
● Detector dust cap to protect the point detector during the construction phase
Function
● Two redundant heat sensors: If one of the two sensors fails, the fire detector
still conforms to the highest response class
● Measures the operating temperature and the temperature inside the
detector housing so that temperature rise can be detected.
● Selectable detection behavior thanks to different parameter sets
Use
● For monitoring rooms in which rapid temperature rise is to be expected in
the event of a fire or if optical detection is difficult
● Can be used addressed
Dummy detector FDX291
Use
● To cover bases that are left empty for prolonged periods of time
