Installation
Amp/Relay Module
1. Locate a suitable mounting location. A dry, cool compartment is a
good choice.
2. Position the amp/relay module on the proposed mounting location.
Using an awl or similar tool, scribe the mounting surface where the
mounting holes are to be drilled. Make sure that this mounting area
allows sufficient ventilation for the amp/relay module.
Caution: As mounting the amp/relay module will require
drilling, it is absolutely necessary to make sure that no other
vehicle components could be damaged in the process. Check
both sides of the mounting surface before starting. If damage
is likely, select a different mounting location.
3. Remove the module from its mounting area, and using a drill bit sized
for a #10 sheet metal screw, drill a hole in each of the areas scribed
in the previous step.
4. Return the module to its mounting location and using #10 x 3/4”
sheet metal screws (provided), secure the module onto its mounting
surface. Be sure to install a #10 internal tooth lock washer (included)
onto each mounting screw before mounting the unit. IMPORTANT:
The amp/relay module case must be either mounted on, or grounded
to the vehicle chassis.
Hand-held Controller/Microphone
The system is controlled using a hand-held controller. This controller is
comprised of a microphone (with Push-To-Talk key) and 12 illuminated
push-buttons.
IMPORTANT: Do not remove the protective plastic from the control
head until the installation is complete!
The mounting bracket for the controller should be located within a
comfortable reaching distance from the operator.
IMPORTANT AIR BAG WARNING! Do not install this product or
route any wires in the air bag deployment zone of your vehicle.
Equipment mounted or located in air bag deployment zones will
damage or reduce the effectiveness of the air bag, or become a
projectile that could cause serious personal injury or death. Refer to
your vehicle owner’s manual to learn the air bag deployment zones
for the vehicle. The User/Installer assumes full responsibility to
determine proper mounting location, based on providing ultimate
safety to all passengers inside the vehicle.
Wiring
WARNING! All customer supplied wires that connect to the positive
terminal of the battery must be sized to supply at least 125% of the
maximum operating current and FUSED at the battery to carry that
load. DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!
Refer to the wire chart on page 6 to help determine the required wire
sizes needed for each circuit.
NOTE: Item numbers reference the illustration found on page 8.
IMPORTANT! Wires connecting to the amp/relay module have the
proper terminals pre-installed from the factory. WHELEN DOES NOT
RECOMEND RE-TERMINATING ANY WIRES.
System Power (Items 1-1 thru 1-4)
1. Locate the high-current Molex™ connector and wires (included)
sized to fit into the system power connectors (items 1-1 thru 1-4).
2. Route the BLACK wire (1-4) from the amp/relay module to the
NEGATIVE battery terminal.
3. Route the three RED wires (1-1 thru 1-3) from the amp/relay module
to the POSITIVE battery terminal. Fuse each of these wires as
follows:
1-1 (Relay) 40 Amp
1-2 (Relay) 40 Amp
1-3 (Siren) 20 Amp
NOTE: These fuses must be located within 2 wire feet of the battery.
Do not install these fuses into their holders until all wiring connections are
completed!
4. Complete the connections and plug the connectors into the amp/
relay module.
Outlets
This system offers 8 Outlets. Each of these outlets provides +12VDC with
a maximum circuit capacity of 8 Amps. If the user desires, the system can
be wired so that a 9th outlet is available (instead of a Dry Contact Relay).
Icon Driver (Item 5-7 WHT/YEL)
This output provides +12VDC with a maximum circuit capacity of 250 mA.
This output becomes active whenever a siren tone is active.
Siren Speaker (Items 6-1 ORG & 6-2 BRN)
1. Route the wires from 6-1 and 6-2 from the amp/relay module to the
siren speaker.
2. Connect 6-1 to the ORG speaker wire (speaker high).
3. Connect 6-2 wire to BRN speaker wire (speaker low).
NOTE: For dual speaker installation, connect the second speakers wires
to the same destinations as the first speakers wires (see page 7).
Radio Rebroadcast (Items 5-1 BLU & 5-6 BLU)
The wires from 5-1 & 5-6 are used to connect your two-way radio’s
external speaker for radio rebroadcast. This is an optional connection and
will not effect the other operations.
Note: Radio rebroadcast will NOT work with amplified remote speakers! If
your remote speaker is amplified (i.e.: contains a power amp circuit in the
speaker assembly), do not enable the radio rebroadcast feature.
1. Locate the two wires that connect the external speaker to the two-
way radio, cut one of them and splice one of the BLU wires into this
circuit.
2. Cut the remaining speaker wire and splice the remaining BLU wire
into this circuit.
Backlighting (Item 5-2 WHT/ORG)
1. Route the wire from 5-2 to the vehicle’s marker light circuit.
2. Splice this wire into this circuit to enable the control head backlighting
to be active whenever the vehicle’s marker light is active.
Inputs
Horn Ring Inputs (Item 5-4 WHT/BLK or 5-9 BLK/WHT)
If Hands-Free siren control is desired, the vehicle horn ring circuit must be
integrated into the siren system as shown in the wiring diagrams on page
7.
