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 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.

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.

Installation
Supplies Required:
• Teflontapeorpipesealant
• Black,whiteandgreenAWG18minimumwiretoconnectalarmto
electric power supply
• 1/2"conduitand1/2"x3/4"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 or
12-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.
• Theswitchbodymustbeintheverticalpositionwiththewaterpipe
horizontal.
• Thewaterflowmustbeinthedirectionmarkedbythearrowonthe
flow switch body.
• Useteflontapeorpipesealant(suppliedbyinstaller)onallwater
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.
• Thealarmmaybemounteddirectlytothedrenchshowerpiping
using the supplied U-bolts and nuts.
• Thealarmcanalsobeboltedtoaflatsurfacesuchasawall
(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. Loosen,butdonotremove,thetwo5/64"hex screws located on the
sides of the alarm horn casing.
2. Runelectricpowerconduit(and3/4"x1/2"adapter, if necessary) and
AWG 18 minimum power wire into the hole in the bottom of the alarm
horn casing.
NOTE: Compliance and conformity to local codes and ordinances is the
responsibility of the installer.
3. There are three wires inside the alarm horn casing for power supply
connections—two for power and one for ground. Using two wire nuts,
connec black to black and white to white. Ground as required.
4. Replace the front grille onto the alarm horn casing being sure the
prong plugs (that are part of the front grille) line up with the socket
slotsinsidethecasing.Tightenthetwo5/64"hex screws. 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:
• Checkthatthecircuitbreakerorfuseissupplyingpowertothealarm.
• Checkthatthedirectionofwaterflowcorrespondstothearrowontheflowswitchbody.
• Checkthatwaterflowissufficient(4gallonsperminuteisrequired).
• Checkallelectricalconnections,includingthepowersupplyandthequick-connectcablefromthealarmtotheflow
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.
• Use1/16"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.
