Installation
IMPORTANT: Power should be supplied
to the alarm by no larger than a 15
amp branch circuit with a dedicated
circuit breaker or fuse and should
not supply power to any other
device. Compliance and conformity
to local codes and ordinances is
the responsibility of the installer.
Step 1: Install the flow switch in the water
supply line
NOTE: Because the flow switch will attach to the
mounted alarm via a 7-foot waterproof cable, the
installer must keep the location for mounting the
alarm in mind when choosing the flow switch
location (see Figure 1).
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
(see Figure 1).
NOTE: 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).
2. Mount the flow switch assembly in the water
supply line.
‡ The switch body must be in the vertical
position with the water pipe in the
horizontal position.
‡ The water flow must be in the direction
marked by the arrow on the flow switch
body.
‡ Use teflon tape or pipe sealing compound
(supplied by installer) on all water pipe
connections.
NOTE: The alarm system is designed to work
properly even if both the eyewash and drench
shower are used simultaneously. The alarm will
continue to operate as long as either the eye wash
or drench shower is still in use.
