IMPORTANT
Read this installation manual completely to ensure proper installation, then file it
with the owner or maintenance department. Compliance and conformity to drain
requirements and other local codes and ordinances is the responsibility of the installer.
Separate parts from packaging and make sure all parts are accounted for before
discarding any packaging material. If any parts are missing, do not begin installation
until you obtain the missing parts.
Flush the water supply lines before beginning installation and after installation is
complete. Test the unit for leaks and adequate water flow. Main water supply to the
eyewash should be “ON” at all times. Provisions shall be made to prevent unauthorized
shutoff.
The ANSI Z358.1 standard requires an uninterruptible supply of flushing fluid at a
minimum 30 PSI (0.21 MPa) flowing pressure. Flushing fluid should be tepid per ANSI
Z358.1.
The inspection and testing results of this equipment should be recorded weekly to verify
proper operation. This equipment should be inspected annually to ensure compliance
with ANSI Z358.1.
Workers who may come in contact with potentially hazardous materials should be
trained regarding the placement and proper operation of emergency equipment per ANSI
Z358.1.

Power should be supplied to the alarm by no larger than a 120 volt AC,
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.

S19-320B, S19-320E Installation

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.

Test The Alarm System
NOTE: Testing the alarm for the first time using the drench shower may expose the flow switch to an unnecessary water
hammer since the downstream piping may be empty of water. The flow switch is designed to withstand such a water
hammer, but using the smaller eyewash flow is recommended.
1. Apply power to the alarm branch circuit. The alarm should remain in the “OFF” position.
2. Make sure the alarm horn cut-out switch is in the “ON” position. This switch is located on the PVC tee beneath the alarm.
3. Open the eyewash valve. The alarm should sound and the strobe light flash shortly after water flows from the system.
4. Use the alarm horn cut-off switch to silence the horn. Flipping the switch down one or two clicks (either the horizontal or
DOWN position will work) should shut off the horn but allow the strobe light to keep flashing.
5. Shut off the eyewash flow valve. The strobe light should stop flashing.
6. Reset the alarm horn cut-off switch to its uppermost “ON” position.
7. Repeat the tests in procedures 1-6 above, this time using the drench shower only.
Troubleshooting
1. If the alarm (horn and strobe light) does not operate when water flows:
• Check that the circuit breaker or fuse is supplying power to the alarm.
• Check that the direction of water flow corresponds to the arrow on the flow switch body.
• Check that water flow is sufficient (4 gallons per minute is required).
• Check all electrical connections, including the power supply and the quick-connect cable from the alarm to the flow
switch.
Strobe flashtube replacement
1. Loosen the locking band and remove the clear plastic dust cover from the top of the strobe light.
2. Loosen (but do not remove) the three screws holding the amber dome in place. Rotate the dome slightly clockwise and
remove the dome.
3. Remove the flashtube assembly by simply unplugging it from the top of the strobe light.
4. Replace the flashtube assembly with a new one BUT avoid touching the flashtube glass with your fingers. Be sure the
flashtube assembly is firmly plugged into the socket.
5. Reattach and tighten the amber dome.
6. Reattach and tighten the clear dust cover.
7. Test the alarm as described in “Test the Alarm System.”
Alarm system maintenance
The Bradley Alarm System is designed to be virtually maintenance free. An occasional damp cloth wiping of the clear dust cover is
all that is needed to ensure maximum visual attention-getting ability.
The alarm horn is factory-set at the loudest possible sound level, 103 decibels at 10 feet. This sound level will attract
attention in shop areas with loud background noise levels or at large distances outdoors. If the alarm is used in a more quiet
environment or over shorter distances, the sound level is easily adjustable to lower levels (down to 78 decibels at 10 feet)
with a simple external adjustment.
• Use 1/16" Allen wrench to adjust the sound to the appropriate alerting level. The adjusting hex screw is located on the
front centerline of the horn grille about an inch from the bottom. Turning the hex screw clockwise quiets the horn.
Remote Sensing Option
If remote sensing is wanted, remove the pipe plug from the back of the junction box. Connect the extra black wire (common to both
switch arrangements) and the blue wire (normally open switch arrangement) or red wire (normally closed switch arrangement) to
your application per local electrical codes. The switch is rated at 5 amps at 120 volts and is isolated from the contacts used by the
alarm system. Your connection should be water tight.
