Description

DHI-HY-1431 Addressable 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, thus ensuring the buses operate normally. 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.
