2Mount the Signaling Assembly in Wall
C
Chose a location for mounting the
signaling assembly. The signaling
assembly should be mounted at least
7 feet above ground level for best
visibility.
Recessed signaling system display needs to be installed in a location where it is not in the
direct spray pattern of a drench shower.
D
Size appropriate hole to mount the
signaling system in. The wall must
have sufficient depth to accommodate
the flush mounting of the control box.
EMount the control box to the in wall
studs using the holes provided and
fasteners (customer provided).
3Connect Signaling Assembly to Flow Switch
Make sure cable is not taut to prevent
undue stress to cable and connector.
A
Connect the flow switch to the
signaling system 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.
B
Tighten the locking collar on the
female cable socket by rotating it
clockwise after plugging in. This
makes a good watertight connection.

WARNING To prevent personal injury and damage to the components, follow all manufacturer's
warnings and instructions when performing any maintenance or installation of
components used in this emergency signaling system.
A
Run electric power conduit (3/4"
conduit hub, customer provided) and
AWG 18 minimum power wire into
the hole to the floating terminal block
per the wiring schematic.
B
Re-attach connector from control box
to front panel (located on the lower
right hand corner of the control board).
Compliance and conformity to local codes and
ordinances is the responsibility of the installer.
CRe-attach the cover and tighten the
four screws.
Do not exceed 14 AWG wire.
5Test the Signaling System
Testing the signaling system 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.
A
Apply power to the alarm branch
circuit. The alarm should remain
in the OFF position and the green
beacon light will turn on at a steady
state.
B
Open the eyewash valve. The horn
should sound and the beacon light
will become a signal light and flash
amber shortly after water flows from
the system.
C
Close the eyewash valve. Once flow
is discontinued, the horn will shut off
and the beacon/signal light return to
green steady state.
ERepeat steps A through D, this time
using the drench shower only.
Discontinuing the flow will automatically
reset the silence feature.
The signaling system is designed to work properly
even if both the eyewash and drench shower are
used simultaneously. The signaling system will
continue to operate so long as either the eyewash
or drench shower is still in use.
The horn will continue to sound and
beacon/signal light will continue to flash
as long as the fixture is activated.
See wiring diagram and schematic
on pages 11-12. DTurn on supply power to the signaling
system. Test the signaling system at
this time.

Servicing of Lights
S19-322 LED Light/Horn Replacement
ADe-power the control box by
observing standard lock-out tag-out
practices.
B
To disconnect the wire leads of the
light requiring the bulb to be replaced,
use a small blade screwdriver to
depress the orange terminal release
tab adjacent to the wire's location.
With the tab fully depressed, the
wire can be easily removed from the
terminal location.
C
Remove the 4 nuts which attach the
light to the front panel and remove
light. This is a sealed light and has
no serviceable components, the
complete housing must be replaced.
D
Using the old light for reference,
prepare the replacement light's lead
wire and exposed conductor's lengths.
EReverse the disassemble process to
reinstall the light.
F
Check that the signaling station is
functioning properly once the power
is restored by activating the fixture
attached to the signaling station.
Signaling System Maintenance
The Bradley Emergency Signaling 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 horn is factory-set at the loudest possible sound level, 85 decibels at 3 feet.
Remote Sensing Option
Flow Switch Capability
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 125/250VAC and is isolated from the contacts used by the signaling station. The customer supplied connections
should be of a type equal to or greater than the junction box's rating to maintain the integrity of the system.
See wiring diagram and schematic on pages 11-12.

Troubleshooting
Problem Cause Solution
The signal light and horn (if
applicable) does not operate
when water flows.
No power to the signal station. Check that the circuit breaker or fuse is supplying power to the
signal station
Component failure. Check the two 3 Amp 24VDC fuses on the print circuit board in
the signal station enclosure.
No input power. Check that there is 24VDC being supplied from the power supply
mounted on the print circuit board in the signal station enclosure.
Water flowing in wrong
direction for flow switch body.
Verify that the direction of the water flow corresponds to the arrow
on the flow switch body.
Insufficient water flow. Check that water flow is sufficient (2.4 gallons per minute is
required).
Installation error. Check all electrical connections, including power supply at the
quick-connect cable, from the signal station to the flow switch.
Horn sounds and signal light
does not light.
Component failure. Check light connections and filament in the light.
Beacon light does not
operate. (This light should
turn off when the signal light
turns on and back on when
the signal light turns off.)
Fixture in use. Make sure that the flow switch contacts are open (horn and/or
signal light are not ON).
Power disconnected in error. Check that the circuit breaker or fuse is supplying power to the
signal station.
Component failure. Check the 3 Amp 24VDC fuses on the print circuit board in the
signal station enclosure.
No input power. Check that there is 24VDC being supplied from the power supply
mounted on the print circuit board in the signal station enclosure.
