DAHUA ISOLATOR MODULE (DHI-HY-1431)

DHI-HY-1431 Isolator Module is a mated product of the Addressable
Fire Alarm Control Panel, locating at intervals on the loop. When a
short circuit fault occurs at a place at the output end of the short circuit
isolator in the bus circuit, the isolator module will cut off all equipment
connected to the output end of it. After elimination of the short circuit
fault, the isolator module can automatically connect the isolated loop
section to restore power and data, help confirm the location suffering
a short circuit fault. It ensures that in case of a short circuit, only the
section between the isolators will be affected. The maximum number of
equipment between isolators is 32. Isolator Module is recommended to
be installed in electrical wells or in modular boxes in fire compartments.
