INSTALLATION AND MOUNTING
Magnetic Mounting:
WARNING: As with any magnetically mounted warning device, its use on the exterior of a moving
vehicle is at the sole discretion and responsibility of the user.
This magnetic mount provides a secure, temporary installation in most circumstances and is
recommended for stationary use only.
The magnetic based beacon provides a secure, temporary installation. The beacon should be placed in
the center of the roof where the least amount of curvature occurs. Check the magnet for debris before
installation. Any foreign matter can reduce holding power and scratch the vehicle. The roof surface
should be dry and have a dull, not glossy finish. A glossy, highly waxed surface will reduce the magnet’s
holding power. When placed, the beacon should adhere firmly. The user should not attempt to drive
with the beacon in place should the unit slide or move easily.
Voltage: 120-277 V AC Stepped Down to 10-30V DC
Permanent Mounting:
The permanent mount beacon provides a secure, permanent installation. Use the supplied foam
gasket and screws to mount the beacon in the desired location. Wire routing should be taken into
consideration when choosing a mounting location.
Pipe Mounting (optional):
The beacon base will accept a standard 1" NPT pipe. Hand tighten the beacon base on the pipe thread
until the pipe bottoms out inside the unit. DO NOT over tighten- Base is plastic.
WIRING INSTRUCTIONS
Magnetic Mounting:
The magnetic mount beacon is equipped with a light plug rocker switch, that plugs into a 12 Volt DC
cigarette lighter outlet; rotate and push with reasonable moderate force to insure the best possible
connection.
Permanent Mounting:
The beacon is terminated with a 6" long 4-wire cable harness that may be connected as follows:

OPERATION:
Synchronization (Permanent Mount Only):
To sync two beacons, configure both lights to display the same Phase 1 pattern. With the power off,
connect the YELLOW wires from each light together. When the lights are activated, their patterns will be
synchronized. To configure the two lightheads to alternate their patterns, advance the pattern of either
beacon to the Phase 2 mode of the current pattern. A maximum of 8 lights may be synchronized.
Setting the Flash Pattern (Magnetic Base):
Depress the rocker switch on the lighter plug:
Less than 1 second for the NEXT pattern
1 to 3 seconds for the PREVIOUS pattern
3 to 5 seconds for the DEFAULT pattern
Greater than 5 seconds to TURN OFF the beacon
Setting the Flash Pattern (Permanent Base):
Connect Blue wire to the Black wire (chassis ground):
Less than 1 second for the NEXT pattern
1 to 3 seconds for the PREVIOUS pattern
3 to 5 seconds for the DEFAULT pattern
Greater than 5 seconds to TURN OFF the beacon
