f.
Route the 18-gauge green wire to a known good
chassis ground near the 331114 control. To provide a good ground
connection, scrape any painted surface to bare metal.
2.
AUX IN and AUX OUT Connections.
When a positive (+)24 volts is applied to the AUX IN
connection, the alternating flash pattern is activated.
The AUX OUT connection will provide a ground to
activate a ground-activated relay (user-supplied) when the AUX
switch is operated. To perform the wiring for these connections,
proceed as follows (see figures 2 and 3):
CAUTION
To avoid damage and ensure proper operation, the wires
MUST be installed in the seven position connector as
shown in figure 3.
a.
Connect a user-supplied 18-gauge wire to the
seven-position connector’s AUX IN connection. Route the wire to a
user-supplied external switch which will provide a positive (+) 24-
volts (such as Federal Signal Model SW400SS) when activated.
b.
Connect a user-supplied 18-gauge wire to the
seven-position connector’s AUX OUT connection. Route the wire to
a user-supplied ground-activated relay for activation of an external
device. Install an in-line, user-supplied, 1 ampere fuse between the
control and the relay.
3.
DASH LIGHTS Connection.
See figures 2 and 3. Connect a user-supplied 18-
gauge wire to the seven-position connector’s DASH LIGHTS
connection. Route the wire to the vehicle instrument light circuit
(if backlight dimming is required) or the accessory terminal of the
ignition switch and terminate as required.
4.
SignalMaster Cable Connections.
a.
Route the SignalMaster cable towards the
control unit, while being careful not to scrape the wires on any
sharp edges.
b.
If necessary, cut the cable to the appropriate
length.
c.
Connect the 22-gauge wires to the eleven-
position connector as shown in figures 2 and 3. Positions 1 and 8
will not be used. Positions 9 and 10 are used for external lamp
connections. Each of these two positions provides an alternating
ground signal to activate external lamps. The maximum current
draw for each position is 2-amperes.
d.
Crimp a 0.187" wide spade receptacle on the
SignalMaster cable red (lamp common) wire and connect it to the
controller's LAMP COM (red) input.
D.
Inspection and Final Installation.
1.
Ensure that there are no loose wire strands or other
bare wires which may cause a short circuit. Also, all wires must be
protected from any sharp edges which could eventually cut
through the insulation.
2.
Plug the seven-position connector into the mating
connector on the control unit, and apply pressure until it locks into
place.
3.
Plug the eleven-position connector into the mating
connector on the control unit, and apply pressure until it locks into
place.
4.
Connect the remaining end of the 14-gauge red wire
from the +BAT spade connector to the (+) positive terminal of the
battery using an in-line, user-supplied fuseholder and 15A fuse.
Locate the fuse as near the battery as possible to protect the entire
length of wire.
5.
Read and understand paragraph IV OPERATION.
Test for proper operation of all functions.
6.
Secure the mounting bracket to the control unit
with the 1/4-20 hex head, thread forming screws and 1/4" external
tooth lock washers (see figure 1).

OPERATION.
SAFETY MESSAGE TO OPERATORS
Peoples’ lives depend on your safe use of our products. Listed
below are some important safety instructions and precautions you
should follow:
•
Although your warning system is operating properly,
it may not be completely effective. People may not
see or heed your warning signal. You must recognize
this fact and continue driving cautiously.
•
Also, situations may occur which obstruct your
warning signal when natural or man-made objects
are between your vehicle and others, such as: raising
your hood or trunk lid. If these situations occur, be
especially careful.
•
This product controls high intensity LED devices. To
prevent eye damage, DO NOT stare into the light
beam at close range.
•
At the start of your shift, you should ensure that the
light is securely attached and all lamps are operat-
ing properly. The LED display on the control only
simulates the operation of the lamps.
•
If a selected function does not perform properly or if
any of the lamps remain illuminated when the
control is off, disconnect the power connector from
the control unit and contact the nearest service
center.
Failure to follow these safety precautions may result in
property damage, serious injury, or death to you, to passengers, or
to others.
RETAIN AND REFER TO THIS MESSAGE
See figure 4. All controls utilized during normal operation of
the SignalMaster directional light are located on the front panel of
the control unit. The LED display simulates the light pattern being
executed by the directional light.
