Specifications
The contractor shall install an electronically actuated resettable
shutoff valve on the cold water supply of the water heater, as
indicated on the drawing.

closes upon detection of water at the water detector pad sup-
plied with the valve. Lead Free* valves shall be constructed
using Lead Free* materials. Lead Free* Water Detector Shutoff
valves shall comply with state codes and standards, where
applicable, requiring reduced lead content. A water detector
pad shall be installed on the floor beneath the water heater or
in a drain pan supplied by the contractor. The water detector
pad shall be supplied with an integral cable with connector to
connect to the valve control unit. The water detector pad shall
be an electronic sensing device.
The electronically actuated valve shall act to shut off both the

upon detection of water.
A visual and audible indication of actuation shall be initiated
and normally open contacts suitable for connection to remote
monitored alarm actuation shall close.
(Optional: The remote alarm contacts will be connected to a
building alarm system by the alarm contractor).
The valve shall be provided with an integral control unit, a
water dam, a power supply and a power cutout module in
addition to the water detection pad.
