Installation
Supplies Required:
• Teflon tape or pipe sealant
• Black, white and green AWG 14 wire to connect alarm to
electric power supply
• 1/2" conduit and 1/2" x 3/4" adapter bushing for electric
power supply wiring
Step 1: Install the flow switch in the water
supply line
NOTE: The flow switch will attach to the mounted alarm via
a 6-foot waterproof cable. Keep the location for mounting
the alarm in mind when choosing the flow switch location.
1. Choose a location for mounting the flow switch in a
horizontal run of the water supply line. The inlet and
outlet ports of the flow switch must be a minimum of
6 inches from any tees or elbows in the water supply
line.
2. Mount the flow switch assembly in the water supply
line.
• The switch body must be in the vertical position with
the water pipe horizontal.
• The water flow must be in the direction marked by
the arrow on the flow switch body.
• Use teflon tape or pipe sealant (supplied by
installer) on all water pipe connections.
Step 2: Mount alarm assembly to unit
NOTE: Point the alarm speaker in the direction from which
help is most likely to come.
1. Choose a location for mounting the alarm assembly.
The alarm should be mounted at least 7 feet above
ground level for best visibility.
• The alarm may be mounted directly to the drench
shower piping using the supplied U-bolts and nuts.
• The alarm can also be bolted to a flat surface such
as a wall (hardware for this type of installation is
NOT supplied).
Step 3: Connect alarm to flow switch
1. Connect the flow switch to the alarm by plugging the
prewired cable into the socket provided in the flow
switch junction box. The plug and socket have an
alignment pin and groove which makes for error-free
hook-up.
NOTE: To prevent water condensation from dripping onto
the flow switch, make sure the cable is not taut.
2. Tighten the locking collar on the female cable socket
by rotating it clockwise after plugging in. This makes a
good watertight connection.
Step 4: Complete electrical supply
connections
1. Connect the 24 volt AC power to the Alarm System
(using the red and black wires only) in the 6- or 12-foot
power cable provided. Test the alarm system.
