Installation

Supplies Required:

• Teflon tape or pipe sealant
• Black, white and green AWG 18 minimum wire to connect alarm
to electric power supply
• 1/2" conduit and 1/2" x 3/4" adapter bushing for electrical wiring
Step 1: Install the flow switch
NOTE: The flow switch will attach to the mounted alarm via a
6-foot or 12-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 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. For best visibility,
the alarm should be mounted at least 7' above ground level.
• 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. Plug 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. Loosen, but do not remove, the two 5/64" hex screws located
on the sides of the alarm horn casing. Remove the front grille
from the alarm horn to expose the internal wiring.
2. Run electric power conduit (and 3/4" x 1/2" adapter, if
necessary) and AWG 18 minimum power wire into the hole in
the bottom of the alarm horn casing.
NOTE: Compliance and conformity to local codes and ordinances
is the responsibility of the installer.
3. There are three wires inside the alarm horn casing for power
supply connections—two for power and one for ground. Using
two wire nuts, connect black to black and white to white.
Ground as required.
4. Replace the front grille onto the alarm horn casing being sure
the prong plugs (that are part of the front grille) line up with
the socket slots inside the casing. Tighten the two 5/64" hex
screws. Test the alarm system.
