INSTALLING YOUR PUBLIC ADDRESS SYSTEM

The Horn Blasters PA-100H can be installed in many different types of vehicles. The guidelines for the installation of the product are written so that no matter what vehicle is being used, the installation and operation will be simple and straight forward.
SELECTING A MOUNTING LOCATION
The following guidelines will help you select a good location.
A) The control box (head unit) should be mounted on a metal surface to aid heat dissipation. Be sure that this surface is not one that either generates or is exposed to excessive heat during normal operation of the vehicle.
B) Do not select a location where the unit will be exposed to potential damage from any unsecured or loose equipment in the vehicle.
C) Be sure the area selected will not allow the unit to be exposed to water.
D) When routing the wires, it is important to choose a path that will keep these wires away from excessive heat and from any vehicle equipment that could compromise the integrity of the wires (ex. trunk lids, door jams, etc.)
E) When the best mounting location has been determined, securely fasten the unit to its mounting surface using the supplied hardware.
Caution: As it will be necessary to drill holes into the mounting surface, the installer MUST be sure that no vehicle components or other vital parts could be damaged by the drilling process. Check both sides of the mounting surface before drilling begins.

1. Position the unit in its proposed mounting location to ensure that it fits properly. With the unit in place, insert an awl or other suitable tool into the mounting screw area of the unit and scribe the areas that are to be drilled.
2. Remove the unit from its mounting area and using as appropriately sized drill bit, drill a hole in each of the areas scribed in the previous step.
3. Return the unit to its mounting location and using the supplied screws, mount the unit onto its mounting surface.
   Important Disconnect the ground (Negative -) terminal from your battery until you are finished making all electrical connections.

WIRING YOUR PA

1. Make sure all connections have a good contact and are secure. Use the provided quick-connect terminals or butt connectors to make connections between all wires.
2. Make sure you have a good, clean ground. Clean all grime from the grounding location until you have bare metal or run a wire to the negative terminal on the battery to insure a clean ground.

ACCESSORY SWITCHES

IMPORTANT: We do not offer support on accessory switches and any accessories you attach to the PA system.

• Your amplifier comes with two optional accessory switches that may be used to control other automotive accessories. These switches are optional to use.
• To power high-amp devices and to reduce risk of damage to your amplifier, use these switches each with a relay. You can use a 4-pin relay to facilitate toggling an accessory on and off. To do this, please follow the high-amp diagram on page 6.
• When wiring the switches, the inputs may be negative or positive. The output will be the same as the input per switch. (e.g. Attach ‘Accessory 2 Input’ to positive: when the second toggle switch is turned on (I), ‘Accessory 2 Output’ will be a positive; when it is o (0) the output will be dead/not connected).

WIRING DIAGRAM

IMPORTANT: Disconnect the ground (Negative -) terminal from your battery until you are finished making all electrical connections.

• The control harness in the diagram is a representation of the harness at the back of the amplifier.
• The yellow and blue wires may be used to wire up accessories. Please refer to the ‘Relay Wiring Diagram’ section in the manual on page 6.
• If your accessories will draw less than 8 amps each, you may you may connect your accessories directly to the yellow or blue wire. If your accessories pull more than 8 amps then follow the relay wiring diagram on page 6.
• The speaker wires (brown/blue) may be reversed. This will reverse the speaker phase and should make no apparent difference to the listener. Ignore the fact that the speaker has brown/blue wires.

FINISHING UP

Once you have finished your installation, make sure the gain of your amplifier us turned to the ‘off’ position, the accessory switches are in the off (0) positions, fuses are inserted into any fuse block you installed, and finally to reconnect the ground terminal of  our
battery.

TESTING YOUR INSTALLATION
Before using your public address and siren system, you should test the work you’ve done.
