4 Test the Signaling System
Testing the signaling assembly 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 beacon and
area light illuminate (if applicable) .
The signal light will not illuminate .
B
Open the eyewash valve . The horn
should sound and the signal light
flash shortly after water flows from
the system . If there is the optional
beacon light, this beacon light will
turn off once the fixture is activated
(the signal light will stay on, flashing) .
The area light will always stay on .
C
If present, use the auto reset on/
off switch to silence the horn during
a flow event . Toggling the switch to
silence mode will shut off the horn
but allow the signal light to keep
flashing . All units can be silenced by
deactivating the flow .
D
Shut off the eyewash flow valve . The
signal light should stop flashing and
the beacon light (if applicable) will
turn back on at a steady state .
E
Repeat steps A through D, this time
using the drench shower only .
Discontinuing the flow will automatically
reset the silence feature.
The alarm signaling system is designed to work
properly even if both the eyewash and drench
shower are used simultaneously. The alarm will
continue to operate so long as either the eyewash
or drench shower is still in use.
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 .
Remote Sensing Option
Flow Switch Capability (see supplied wiring diagram)
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 .
Control Box Capability (see supplied wiring diagram)
The control box is supplied with 2 sets of double pole double throw relay contacts which change state with flow .
These contacts can be externally powered or powered by the 24VDC un-switched outputs; combined load cannot
exceed 770mA when internal DC power is used . If contacts are externally powered, the contacts are rated for a
maximum 160 volts at 5 amps .
