Description
The Water Motor Alarm Gong and the Retarding Chamber are optional accessories that can be used in the Wet Sprinkler System. The Water Motor Alarm Gong is hydraulically operated and is used to sound a local alarm in case of water flow. The Retarding Chamber is used in situations where excessive water pressure occurs in order to collect excess water from the Alarm Valve and feed water back into the main drain before activating the alarm.
