ACC-1 Dry Pipe Accelerator
Mechanical accelerator
This quick-opening dry pipe accelerator reduces the time for valve operation when a sprinkler is activated.
- UL and C-UL Listed, FM and LPCB Approved
- Designed for use with Model DPV-1 dry pipe valves — 2-½-, 3-, 4- or 6-inch sizes
- Speeds operation of the dry pipe valve upon loss of air pressure
For Use With DPV-1 Valves
The Tyco® Model ACC-1 dry pipe accelerator attaches to the Tyco® Model DPV-1 dry pipe valve to allow faster valve operation. It automatically adjusts to both small and slow changes in system pressure, but it trips when there is a rapid and steady drop in pressure (like during a sprinkler operation).
Upon tripping, the accelerator transmits system air pressure to the intermediate chamber of the Model DPV-1 dry pipe valve. This neutralizes the differential pressure holding the Model DPV-1 dry pipe valve closed and permits it to open.
The ACC-1 has a unique, positive action; an internal anti-flood device; and a ball float that combine to prevent water and water-borne debris from entering the more sensitive operating areas of the accelerator.
