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
