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 (see wire chart on page 8).
NOTE: Item numbers reference the illustration found on page 6.
IMPORTANT! Wires connecting to the amp/relay module have the
proper terminals pre-installed. If the customer needs to re-terminate
these wires for any reason, the proper tool MUST be used to insure
proper crimping.
System Power (Item 5)
1. Locate the 4-position Molex™ connector (item 5).
2. Using appropriately sized wire, extend the two RED wires to the
Positive (+) battery terminal. Fuse each wire independently @ 40
Amps. DO NOT install these fuses until the wiring for the entire
system has been completed.
3. Using appropriately sized wire, extend the two BLACK wires from the
CanTrol™ module to the vehicle’s chassis ground. This is typically
adjacent to the battery.
4. Complete the connections and plug the connectors into the
CanTrol™ module.
Ignition Sense (Item 13)
1. Locate the RED/WHT wire at J17-7.
2. Connect this wire to the vehicle ignition switch. This will allow the
CanTrol™ system to be turned off with the ignition switch.
Outputs
CanTrol™ offers the following outlets:
32 LED outputs (2.5A Max. each)
8 High Current outputs (10A Max. each)
3 Aux. outputs (250mA Max each)
Siren Speaker (Item 7)
1. Route the ORG and BRN wires from the CanTrol™ module to the
siren speaker.
2. Connect ORG wire to the WHT speaker wire (speaker high).
3. Connect BRN wire to BLK 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 9).
Radio Rebroadcast (Item 13)
Two BLU wires (J17-8 & J17-16) 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 13)
Note: The CanTrol™ backlight circuit has been designed to accept any of
the following:
0 VDC Input (off)
12VDC (on)
A Pulse Width Modulated (PWM) input with a range of 0% - 100% duty
cycle@100Hz (i.e. dimmer circuit)
1. Route the WHT/BLK wire (J17-5) from the CanTrol™ module 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
The CanTrol™ system inputs operate as follows:
Logic Inputs - These are programmable inputs and their default
configuration and activation polarity is as follows:
Active High/Low
Logic Input 1 (J17-1) - Horn Ring Input (Ground Activated). Identical
in operation to the Manual button when the Horn Transfer Relay has
been activated.
Logic Input 2 (J17-2) - Park Sense 1 (Ground Activated). Terminates
siren operations.
Logic Input 3 (J17-3) - Unused
When connecting to the vehicle’s transmission neutral safety
switch signal wire, always consult your vehicle’s technical
manual before altering your vehicle’s wiring. Wiring
modifications may compromise your vehicle’s safety and/or
performance.
Logic Input 4 (J17-4) - Unused
Active High Only
Logic Input 5 (J17-9) - Unused
Logic Input 6 (J17-10) - Unused
Logic Input 7 (J17-11) - Unused
Logic Input 8 (J17-12) - Unused
Analog Inputs - There are three (3) analog inputs (J17-5, J17-13 and
J17-6). Their input voltage may range from 0 to 12VDC. By default,
Analog Input 2 and Analog Input 3 are disabled and can be enabled as
needed.
The remaining inputs are designated to be used for Ignition Sense (J17-7)
and Radio Repeat (J17-8 & J17-16).
Hands-Free Siren (Items 4 & 13) (Optional)
1. Using a customer supplied relay capable of handling the current of
your vehicle horn, connect as shown below.
Control Head Strain Relief
1. Route the control head cable (provided) from
the CanTrol™ module to the designated
mounting location. Plug this cable securely into
the rear of the control head. Be sure to route
the cable through either of the two recessed
pathways (shown here). This will prevent the
cable from being accidentally disconnected or
pinched by the control head.
