These valves are also listed as a checking device, which eliminates the need for a separate check valve. When
sprinklers on a given floor are fed from dual risers, the Pressure-Matic® valve acts as a check valve to prevent
loss of sprinkler water supply in the event of damage to one riser.
Supervisory Switch Mounting Brackets
Brackets are available for the attachment of the following listed supervisory switches to the Pressure-Matic®
valves.
