Ignition Sense Connection
•
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.
Important Notices
The 6600H/6601H is designated 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.
