Isolator 6202L
Description:FD6202L Isolator
Its purpose is to isolate the line (loop) segment when a short circuit is detected. Thus the fire detectors, which are not located in the short circuited segment, continue operation. When the short circuit is eliminated the isolator automatically enters inactive state. Usage of isolators is very effectual in Loop configuration, where the possibility of applying power to both loop ends is combined with system failures reduction.
Technical data:
Operating voltage 22(±4)VDC
Current consumption in quiescent mode < 100 mA
Current consumption in alarm mode 5 mA
Sensitivity in short circuit state:
The unit is activates at line resistance value <20Ω
and output resistance value of the power source >20Ω
It is restored at line resistance value >2.1KΩ
And output resistance value of the power source >20Ω
Operation temperature range Minus 10oC – 50oC
Dimensions (base included) Ø106 x 48 mm
Weight (base included) 0.200 kg
