Vecima 66xxH Beacon Family
Important Notices
The 66xxH beacon models are designed to operate from 8 to 30 volts DC.
8V is the minimum voltage at which the
device will operate reliably.
The user is responsible for ensuring the voltage supplied to the beacon remains in this
voltage range to include transient voltage spikes and load dump voltages. Failure to comply may damage the beacon.
The current draw under normal operating conditions is approximately 100mA at 12V.
The beacon should never be connected to the same power source as the vehicle Electronic Control Module
(ECM), as this may adversely affect the vehicle electronics.
Failure to use the proper 3-amp fuse or to install the fuse in the recommended location could cause a vehicle fire
hazard. The fuse provides overload protection for the power cable and the beacon. The wiring installed between the
fuse and primary vehicle power is not protected from overheating if a short should occur.
Failure to install the ignition sense correctly will result in erroneous data being reported from the beacon. This may
result in false or incorrect reporting of vehicle starts, stops, ignition on and off.
The power harness included in the installation kit contains 14 wires, 3 of which are bundled together. The bundle contains the
8-30V constant power (red), ground (black), and ignition sense (white) wires.
Notes
•
Connect the wiring harness to the power and ignition source, as well as any I/O sources (if used), before attaching the
harness to the beacon.
•
If wiring harness wires need to be extended, use the same gauge wire and solder the extension wire on, then insulate with
heat shrink tubing or electrical tape.
•
Ensure that no wires are routed near heat sources.
Power Connection Instructions
•
Connect the black (ground) wire to battery negative or the vehicle chassis – this wire
must
be connected first, before the
power or ignition sense wires. Be sure the grounding screw is not painted or coated with an insulating material.
•
With the vehicle’s ignition turned OFF, use a multimeter to assist in finding a suitable, constant 8-30V power connection
point – directly to the vehicle’s battery may be best.
Important Note:
The red (power) cable is configured with an in-line
3-amp fuse. This fuse must be installed as close as possible to the primary power source connection.
•
Ensure that any wires in the wiring harness that are not to be connected do not come in contact with power, ground, or any
other voltage. Insulate them with electrical tape.
Ignition Sense Connection
•
Important Note:
The ignition sense connection is mandatory. Failure to install the ignition sense correctly will result in
erroneous data being reported from the beacon.
•
Find a source of 8-30V that is switched on and off with the ignition key in the run position (accessory position is not
acceptable). This connection should produce 8-30V when the vehicle ignition is ON and 0 Volts when the vehicle ignition
is OFF. Connect the white (ignition sense) wire to this point. Voltage transitions must occur instantly. Gradual or stepped
transitions from one voltage to another may not be detected.
