1. 

Proper installation combined with operator training in the use, care, and maintenance of emergency warning devices are essential to ensure 

the safety of you and those you are seeking to protect.

2. 

Exercise caution when working with live electrical connections.

3. 

This product must be properly grounded. Inadequate grounding and/or shorting of electrical connections can cause high current arcing, 

which can cause personal injury and/or severe vehicle damage, including fire. 

4. 

Proper placement and installation are vital to the performance of this warning device. Install this product so that output performance of the 

system is maximized and the controls are placed within convenient reach of the operator so that s/he can operate the system without losing 

eye contact with the roadway.

5. 

Do not install this product or route any wires in the deployment area of an air bag. Equipment mounted or located in an air bag deployment 

area may reduce the effectiveness of the air bag or become a projectile that could cause serious personal injury or death. Refer to the 

vehicle owner’s manual for the air bag deployment area. It is the responsibility of the user/operator to determine a suitable mounting location 

ensuring the safety of all passengers inside the vehicle particularly avoiding areas of potential head impact.

6. 

It is the responsibility of the vehicle operator to ensure during use that all features of this product work correctly. In use, the vehicle operator 

should ensure the projection of the warning signal is not blocked by vehicle components (i.e., open trunks or compartment doors), people, 

vehicles or other obstructions.

7. 

The use of this or any other warning device does not ensure all drivers can or will observe or react to a warning signal. Never take the right-

of-way for granted. It is your responsibility to be sure you can proceed safely before entering an intersection, driving against traffic, respond-

ing at a high rate of speed, or walking on or around traffic lanes.

8. 

This equipment is intended for use by authorized personnel only. The user is responsible for understanding and obeying all laws regarding 

warning signal devices. Therefore, the user should check all applicable city, state, and federal laws and regulations. The manufacturer as-

sumes no liability for any loss resulting from the use of this warning device.

Do not install and/or operate this safety product unless you have read and understand the safety information

contained 

Failure to install or use this product according to manufacturers recommendations may result in property damage, serious injury, and/or death to 

those you are seeking to protect!

WARNING!

Installation & Mounting: 

Permanent Mounting:

 Select the desired location on a flat surface for the 

strobe beacon to be mounted. The visibility of the strobe flash and ease 

of wiring access should be taken into consideration in the selection of the 

mounting location. Using the base gasket as a template, mark the three 

mounting hole locations (see Figure 1). Drill the holes using the correct drill 

size to match the hardware. 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. Connect the power wires as shown in the wiring section 

(see Figure 3).

           

     

 

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 ve-

hicle 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.). Ensure that the magnet is kept clean.

!

Caution:

 When drilling into any vehicle surface, make sure the area is 

free from any electrical wires, fuel lines, vehicle upholstery, etc. that could 

be damaged

Wiring Instructions:

The wiring for the strobe is as shown in Figure 3 below. All wiring should be 

a minimum of 18AWG. The positive line must have a 10 amp fuse. A switch 

may be used to control the on/off function. 

Note:

 Power must be shut off 

when changing flash  modes.      

Important!

This unit is a safety device, and it must be

connected to its own separate, fused power point to assure its 

continued operation should any other electrical

accessory fail.
