Permanent Mounting:
1. Select the desired location on a flat surface for the
beacon to be mounted. The visibility of the flash and
ease of wiring access should be taken into
consideration in the selection of the mounting location.
2. Using the base gasket as a template, mark the three
mounting hole locations (see Figure 1).
3. Drill the holes using a 7/32” drill size.
4. A fourth hole may be drilled for wire access as shown in
Figure 1, or the wires may be routed through the slot in
the base for external access.
5. Connect the power wires as shown in the wiring section
(see Figure 3).
6. Mount the beacon with #10 hardware.
The 7900 series base comes with 1” NPT threads for pipe mounting.
Pipe Mounting:
WARNING!
Maximum recommended vehicle speed for safe operation using
the Vacuum Mount model is 65 mph (104 km/h), when fitted to
the center of a vehicle roof of steel construction. Higher speeds
could cause the mount to fail, resulting in the beacon flying off
of the vehicle, which could cause damage to other vehicles, and
injury or death to the passengers. The vacuum-magnet mount
is not intended as a permanent mounting for the beacon. The
vacuum-magnet mount unit must be mounted on a flat smooth
magnetic surface (i.e. no fiberglass, ribbed style roofs, etc.).
Insure that the magnet is kept clean.
!
WARNING!
Failure to follow these instructions can result in fire or injury from excessive heat build up.
Operator is responsible for ensuring cigarette adapter fits correctly into cigarette/auxiliary outlet used.
For proper operation, verify cigarette/auxiliary outlet circuit is rated to supply a minimum of 10 amps. (See specifications section for rated current in amperes).
Do not exceed the current rating for the cigarette lighter power outlet recommended by vehicle manufacturer.
Keep cigarette lighter adapter and outlet clean and free of debris.
Do not use the cigarette lighter adapter when wet.
