10. While making sure the EMS Escape lightbar
is spaced equal distance from both ends of the Quick Track
extrusion, secure the lightbar with the provided M8 set
screws.
IV. ELECTRICAL CONNECTIONS.
A. Direct Surface Mount.
1. Route the control cable(s) into the vehicle
and near the eventual location of the user-supplied control
head, control panel, or strobe power supply.
2. For proper light operation, the control cable
must be properly terminated inside the user-supplied
control head. Table 1 shows the recommended control cable
wire colors for various light bar functions. Using Table 1 as
a guideline, complete the applicable electrical connections
for the functions/options installed in your EMS Escape
lightbar. Switch current capacities should be at least 15
amps. If more than 4 rotators are connected to the same
wire, switch current capacities should be at least 20 amps.
EMS Escape light bars that are equipped with
strobes require the use of an external Federal
Signal Power Supply. Each individual strobe head
is supplied with its own strobe cable and accessory
kit.
3. Strobe Models Only.
See figure 5. The cable leads must be termi-
nated with the supplied connectors. The supplied connec-
tors mate with the connectors on Federal Signal power
supplies. Wiring should not be performed until the unit is
mounted as previously described.
Complete the wiring as follows:
a
Route the strobe cables to the Federal
Signal power supply.
b. Crimp the pins on the end of the strobe
head cables. Insert the pins in the connector housing(s) as
shown in figure 5 and push them until they snap into place.
The connector(s) can now be plugged directly into a Federal
Signal strobe power supply. Observe proper wire colors and
placement when assembling the connectors as shown in fig-
ure 5. Refer to the particular Federal Signal power supply
installation instructions for additional wiring details.
Any of the light bar functions can be activated by
applying 12VDC to the appropriate control line.
The heavy black lead (-) must be connected to ve-
hicle ground, to perform a function check.
4. Connect the black lead to chassis ground.
NOTE
NOTE
If wires are shorted to the vehicle frame
or each other, high current conductors can
cause hazardous sparks resulting in electri-
cal fires and molten metal.
Verify that no short circuits exist before con-
necting to the Positive (+) battery terminal.
DO NOT connect this system to the vehicle
battery until ALL other electrical connec-
tions are made and mounting of all compo-
nents is complete.
Failure to observe this WARNING will result
in fire, burns and blindness.
5. SignalMaster Option.
The SignalMaster option is completely wired
at the factory and does not require any additional wiring
inside the light bar. All conductors necessary for control of
the SignalMaster are contained in the smaller cable.
For wiring and operation instructions, refer
to the instruction sheet packed with the applicable Signal-
Master control unit.
B. Quick Track Mount.
1. Route the control cable(s) into the vehicle
and near the eventual location of the user-supplied control
head, control panel, or strobe power supply.
2. The Quick Track mounting system incorpo-
rates the usage of an aluminum extrusion, carriage bolts,
washers, lock washers, and nuts. The Quick Track extrusion
is securely mounted to the vehicles surface with the pro-
vided hardware. The EMS Escape lightbar will mount/hang
on the Quick Track and be secured with the provided set
screws. If service or removal of the EMS Escape lightbar
is required, the set screws can be loosened, thus allowing
the lightbar to be removed, provided that a properly sized
user-supplied connector is installed in line with the control
cable.
Additional slack in the control cable is required
for removal and re-assembly of the EMS Escape
light bar which utilizes the Quick Track mounting.
The user-supplied connector must be accessible
when removing the EMS Escape Lightbar from the
vehicle.
3. For proper light operation, the control cable
must be properly terminated inside the user-supplied
control head. Table 1 shows the recommended control cable
wire colors for various light bar functions. Using Table 1 as
a guideline, complete the applicable electrical connections
