Until you have determined the safe exposure times for your specific application, operators and anyone else in the immediate vicinity should be required to wear an approved hearing protection device. FAILURE TO FOLLOW THIS RECOMMENDATION COULD CAUSE HEARING LOSS!

Mounting:

This siren is designed to be mounted directly onto the dash or other surface through the use of a bail-strap mounting bracket. The unit may also be mounted into your vehicle’s console (if so equipped).

WARNING: Mounting this unit will require drilling. It is absolutely necessary to make sure that no other vehicle components could be damaged in the process. Check both sides of the mounting surface before starting. If damage is likely, select a different location.

Bail-strap mount:

1. Position bail strap in selected mounting location and drill mounting holes, then secure the bail strap to the vehicle.

2. Secure the siren to the bail strap as shown. Tighten the screws firmly.

Console Mount:

Console manufacturers offer mounting kits that include all the necessary hardware and brackets required to mount this unit into their console. The console mount brackets are secured onto the unit the same way the bail bracket is. Please refer to the manual included with your console.

4. Connect the WHITE/GREEN wire to the wire that runs from the horn relay to the horn.

Operation:

Siren in use: This output will become active (+VBAT) whenever a tone is being produced by the siren.

Wiring:

Siren Input Connector - RED: Power - BLACK: Ground

WARNING: All customer supplied wires that connect to the positive terminal of the battery must be sized to supply at least 125% of the maximum operating current and FUSED carry that load. DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!

1. Extend the RED and BLACK wires toward the vehicle battery. To pass the RED and BLACK wires through, you may have to drill a hole in the fire wall. Insert a grommet to protect the wires.

2. Route the RED and BLACK wires along the factory harness towards the battery. Install a fuse block (user supplied) on the end of the RED wire.

Remove fuse from fuse block before connecting wires to battery.

3. Connect fuse block wire to POSITIVE terminal on battery. There must not be more than 2 feet of wire between fuse block and battery. The wire between the fuse and battery is “unprotected”, do not allow it to chafe and short to ground.

4. Connect the BLACK wire to the factory chassis ground.

YELLOW & BROWN - Speaker:

1. Route the YELLOW and BROWN wires toward vehicle siren speaker, along factory wire harness and through firewall at the same point as the RED and BLACK wires.

2. Connect the YELLOW wire to the POSITIVE terminal on the SPEAKER and the BROWN wire to NEGATIVE connection on the speaker.

WHITE/GREEN - Horn Relay:

1. Route WHITE/GREEN wire along factory wire harness and through firewall at the same point as the RED and BLACK wires.

2. Route WHITE/GREEN wire to vehicle’s horn relay. If possible, follow the factory wire harness to this relay.

3. Locate the wire that connects the vehicle horn to the horn relay.
