1 Install the Flow Switch and Mount Signaling Assembly
The flow switch will attach to the mounted alarm via a 6, 12 or 50 foot waterproof cable.
Keep the location for mounting the alarm in mind when choosing the flow switch location.
A
Choose a location for mounting the
flow switch in a horizontal run of the
water supply line.
B
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.
C
Choose a location for mounting the
alarm. For best visibility, the signaling
system should be mounted at least 7'
above ground level.
• The signaling system may be
mounted directly to the drench
shower piping using the supplied
U-bolts and nuts.
• The signaling system can also be
bolted to a flat surface such as
a wall (hardware for this type of
installation is NOT supplied).
NOTICE! If the water supply line will be exposed to
temperatures at or below freezing, the inlet supply
must be freeze-protected 6 inches above the flow
switch tee (freeze protection by others).
