Servicing of Lights
S19-322 LED Light/Horn Replacement
A
De-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 .
E
Reverse 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.
