To install the function legends, proceed as
follows:
Select the appropriate labels from the supplied
sheet of function legends. Peel the labels from the
sheet and apply to the key pad in the area provided
as shown in figure 3-13. Verify that the label is
properly tucked under the retaining ridge on the
pushbutton.
3-9. TESTING AFTER INSTALLATION.
WARNING
All effective sirens and horns produce loud
sounds (120 dB) that may cause permanent
hearing loss. Always minimize your exposure
to siren sound and wear hearing protection.
Do not sound the siren indoors or in enclosed
areas where you and others will be exposed to
the sound.
Before testing, read and understand the sup-
plied Operation and Configuration Instructions. After
installation is complete, test all siren and light
functions to ensure that all functions and controlled
devices operate as intended. Test all vehicle func-
tions, including horn operation, vehicle light systems,
and load management, to ensure proper operation.
Programming is described in the supplied
Operation and Configuration Instructions.
After testing is complete, provide a copy of this
manual to all operating personnel.
C.
Ensure that there are no loose wire strands
or other bare wire which may cause a short circuit.
Also, all wires must be protected from any sharp
edges which could eventually cut through the insula-
tion.
D.
Use an ohmmeter to verify that a short
circuit does NOT exist between the positive (+) and
negative (-) power cable leads. Also, there must be
NO short circuits between the positive (+) wires and
the vehicle chassis.
E.
After performing steps A through D,
connect all black (-) wires to the fusible link on the
front fender. Secure mechanical and electrical con-
nections are required.
WARNING
If wires are shorted to the vehicle frame or
each other, high current conductors can cause
hazardous sparks resulting in electrical fires
and molten metal.
Verify that no short circuits exist before
connecting to the Positive (+) battery termi-
nal.
DO NOT connect this system to the vehicle
battery until ALL other electrical connections
are made and mounting of all components is
complete.
Failure to observe this WARNING will result
in fire, burns and blindness.
F.
Connect all #8 or #10AWG (minimum) red
(+) wires to the positive (+) terminal of the power
source. Also, connect a 14-gauge red wire from the
unused end of the 25-ampere circuit breaker (from
the SignalMaster connector) to the positive (+)
terminal of the power source. Again, secure mechani-
cal and electrical connections are required.
3-8. REPLACEABLE FUNCTION LABELS.
See figure 3-13. Replaceable function labels
identify the switches on the control head. A sheet of
applicable function legends is supplied.
