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

•
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 uninterrupted supply of flushing fluid. Bradley plumbed
emergency fixtures require a minimum of 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.
For questions regarding the operation or installation of this product, visit www.bradleycorp.com
or call 1-800-BRADLEY.
Product warranties and parts information may also be found under ”Products” on our web site at
www.bradleycorp.com.
Power should be supplied to the alarm system transformer 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.

Installation
Supplies Required:
• Teflon tape or pipe sealant
• Black, white and green AWG 14 wire to connect alarm to
electric power supply
• ½" conduit and ½" x ¾" adapter bushing for electric power
supply wiring
Step 1: Install the flow switch in the water
supply line
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
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.
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 14 AWG customer-supplied power cable. Test the alarm
system.

Test The Alarm System
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 to make sure the circuit breaker or fuse is supplying power to the alarm.
• Check to make sure the direction of water flow corresponds to the arrow on the flow switch body.
• Check to make sure the water flow is sufficient (2.4 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.
