An accelerator or exhauster in a dry pipe sprinkler system functions to reduce the time it takes for water to reach the sprinkler heads after a fire is detected, thereby improving the system's response time. In a dry pipe system, the piping is filled with pressurized air or nitrogen. When a sprinkler head activates due to heat, the air pressure in the system must be reduced sufficiently to allow the dry pipe valve to open and release water into the piping network. The volume of air in the piping can significantly de....
