DWCT
The FDO221-CN point-type smoke fire detector uses the optical sensor, and uses the principle of forward scattering, to improve the detection ability of the smoke particles produced by the fire, thus greatly improving the sensitivity of the detection of the open fire or dark fire, to detect the fire as soon as possible.
Characteristic:
-Meet the national standard, GB4715-2005, Point-Type Smoke Fire Detector
-Especially suitable for early detection alarm of dark fire or smoke-generated flame
-The signal is treated by a special arithmetic method (DA) after receiving it
-Strong resistance to environmental factors, including dust, fiber, insects, humidity, extreme high or low temperature, electromagnetic dry
Disturbance, corrosive gas, vibration, non-fire smoke, etc
-Internal integrated short-circuit isolator
-Communicate with the controller via the FDnet loop
Function:
One adopts the scattering light principle of single photosensitive element, forward scattering
-The unique photoelectric sampling smoke chamber can effectively avoid external light interference and conduct accurate detection of fire smoke
-The detection mode of the detector can be selected by the parameter setting, and therefore can be adjusted accordingly to the monitored environmental conditions
