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.

• Designed to trip when system air pressure drops at a rate exceeding approximately 1 psi/minute (0.07 bar/min)
• Upon tripping, it transmits system air pressure to the intermediate chamber of the dry pipe valve, which neutralizes the differential pressure holding the valve closed and opens the waterway clapper
• UL and C-UL Listed, FM and LPCB Approved
• Maximum water supply pressure: 250 psi (17,2 bar)
• Maximum system air (or nitrogen) pressure of 70 psi (4,8 bar)
