Notes:
lDO NOT connect AC power to the alarm until
directed to in these installation instructions to
reduce the risk of shock.
lDO NOT tamper with this device when the
signal circuit is energized. Disconnect power
and wait at least 5 minutes for stored energy to
dissipate before handling to reduce the risk of
shock.
1. UL building wire to make connections from flow
switch, alarm (light / horn) and electrical service.
2. Piping, unions or other connections to meet
required minimum distances for flow switch.
3. 4" x 4" x 2-1/8" J-box and 1-1/2" J-box
extension for adapting alarm for flush mounting
to finished wall.
IMPORTANT: FLUSH WATER SUPPLY LINES
PRIOR TO CONNECTION TO SAFETY
EQUIPMENT.
lFlow Switch must be installed with tee fitting in
horizontal position, switch body in vertical
position (as shown on page 3) and at least 6”
from closest fitting.
lFlow Switch direction of flow is indicated on
switch body.
SUPPLIES REQUIRED:
(not provided by Acorn)
lUse hand tools and wrenches in a manner
which will prevent marring finished surfaces.
Strap wrenches or tools with plastic jaw linings
are highly recommended.
lRefer to fixture rough-in information for location
of supply lines.
4. Surface mounting may require wall anchors and
anchoring hardware for wall mounting alarm
box.
lFragments of Teflon tape or pipe sealant residue
can interfere with the proper operation of this
unit. Ensure pipe sealant methods do not cause
contamination in the system.
WARNINGS:
5. Pipe sealant or Teflon tape for sealing water
connections.

4. Connect the ground wires and ground in
accordance of local and NEC National Electrical
Code requirements. A green ground screw is
provided on the alarm box (or J-box).
STEP ONE:
FLOW SWITCH INSTALLATION
1. Determine location of flow switch in water
supply line. The inlet and outlet ports of the flow
switch must be a minimum of 6” from any tees
or elbows (as shown on page 3) in the water
supply line. Refer to page 6 and rough-in
drawing.
2. Pipe the flow switch in-line of fixture supply
inlet. The switch body must be in the vertical
position with the water pipe horizontal. The
water flow must be in the direction of the arrow
that is marked on the flow switch body. Refer to
page 6 and rough-in drawing.
STEP TWO:
ALARM INSTALLATION
2.Attach alarm hanger plate as shown with angled
flange in an upward orientation.
1. Determine mounting method and location of
alarm. As a recommendation, locate the alarm
near emergency equipment and in a manner
that would allow it to be readily visible by
employees and quick reaction or emergency
personnel when activated.
3. Connect wiring (supplied by others) to the
terminals within the flow switch junction box as
shown in the appropriate wiring diagram. Extra
set of wiring terminals provided for remote
monitoring, not shown.
3. Field wire flow switch to alarm box (or J-box).
Provide electrical service wiring to alarm box (or
J-box). Note: Circuit wiring should not be
energized at this time. It is recommended that
the alarm and other components be installed in
accordance of national and local electrical
codes.
5. Connect flow switch field wiring and electrical
service wiring to alarm terminals as indicated in
wiring diagram.
6. Hang the horn/strobe assembly over the hanger
plate with the mounting screw at the bottom,
then tighten mounting screw to secure..
7. Apply power to the circuit and test to verify
operation.

STEP THREE:
TEST OPERATION
2. Supply water to fixture and flush air from
system.
4. De-activate safety equipment. Alarm horn and
strobe should now automatically de-activate.
1. Apply power to alarm circuit. Unit should not be
operating if safety equipment is not activated.
3. Activate safety equipment. Alarm horn should
be sounding and strobe light should be flashing.
ASW SILENCING SWITCH ONLY. Test
silencing switch. Push silencing button, while
alarm is active; the horn should stop sounding
and the strobe should continue to flash.
To reset -ASW Silencing Switch: Pull button
firmly, an audible “pop” should be heard and a
yellow band should be visible near the end of
the mushroom button. NOTE: If the yellow band
is not visible, switch is NOT reset and the horn
will not sound the next time alarm is activated.
