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 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.

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, 108 decibels at 2 feet.

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.
