WARNING!

Mount the siren with the (2) supplied #8 screws into a secured portion of
sheet metal. See Fig. 1.

Remove the backing from the adhesive faceplate and place the
faceplate over the three hole bracket, see Fig. 2. Should you wish
to install a switch for a beacon, carefully cut the faceplate with a
sharp knife from the front to expose the extra hole in the bracket
and then mount the bracket with the remaining (2) #8 screws. The
bracket should be mounted in a location that will provide
convenience for the operator.

For custom installations, such as in a console or in-dash mounting, the
three hole bracket may be used as a drilling template and the faceplate then
applied directly to the dash or console surface.

All devices should be mounted in accordance with the manufacturer's instructions and
securely fastened to vehicle elements of sufficient strength to withstand the forces applied to
the device.
Ease of operation and convenience to the operator should be the prime consideration when
mounting the siren and controls. Adjust the mounting angle to allow maximum operator
visibility.
Do not mount the Control Head Module in a location that will obstruct the drivers view.
Devices should be mounted only in locations that conform to their SAE identification code as
described in SAE Standard J1849. For example, electronics designed for interior mounting
should not be placed underhood, etc.
Controls should be placed within convenient reach* of the driver or if intended for two person
operation the driver and/or passenger. In some vehicles, multiple control switches and/or
using methods such as "horn ring transfer" which utilizes the vehicle horn switch to toggle
between siren tones may be necessary for convenient operation from two positions.
*

Convenient reach is defined as the ability of the operator of the siren systems to manipulate

the controls from his normal driving/riding position without excessive movement away from
the seat back or loss of eye contact with the roadway.

Wiring

Wire should be #16 gauge, or larger for all connections to the switch, push-button (3050), and the
siren unit. Speaker wire should be #18 gauge or larger. For protection of the wiring and the siren
unit, the in-line fuse and fuseholder supplied should be located as close to the battery as practical.
For proper operation, ground the siren unit negative (earth) terminal to the vehicle frame as close to
the unit as possible. Be sure to scrape away the paint down to the bare metal.
For maximum reliability, it is recommended that all connections be soldered with 60/40 resin core
solder. Should you prefer to crimp the terminals to the wires, be sure that all crimp connections are
tight and that the wire cannot be pulled loose from the terminal. It is further recommended that
wirenut connections be soldered first.
Route all wiring in such a manner as to prevent abrasion between the wires and the metal vehicle
surfaces. Cut off and discard any excess wire.

Larger wires and tight connections will provide longer service life for components. For high
current wires it is highly recommended that terminal blocks or soldered connections be used
with shrink tubing to protect the connections. Do not use insulation displacement
connectors (e.g. 3M

®

Scotchlock type connectors). Route wiring using grommets and

sealant when passing through compartment walls. Minimize the number of splices to
reduce voltage drop. High ambient temperatures (e.g. underhood) will significantly reduce
the current carrying capacity of wires, fuses, and circuit breakers. Use "SXL" type wire in
engine compartment. All wiring should conform to the minimum wire size and other
recommendations of the manufacturer and be protected from moving parts and hot
surfaces. Looms, grommets, cable ties, and similar installation hardware should be used to
anchor and protect all wiring.
