Helpful Notes

• Mounting: Keep compressors high/dry; isolate from heat and use rubber mounts to reduce vibration.
• Electrical: Trigger the horn via relay; fuse near the battery, and loom wires through grommets.
• Legal: Train horn use on public roads may be restricted—check local laws.

Frequently Asked Questions

Do I need onboard air to run a train horn?

Yes—horns require compressed air. Start with an onboard air kit like HP10163 or step up to HP10164 for more reserve.

What pressure switch range should I use?

Common ranges are 85–105 PSI or higher depending on horn spec. See Pacbrake HP10111 for a proven 85–105 PSI option.

Is there a plug-and-play kit?

Pacbrake’s HP10213 and HP10237 bundle horns and onboard air to simplify parts selection.

Which switch should I use to trigger the horn?

For a clean dash install, use the Kleinn 320 Terminator push button or a relay-driven momentary switch.

Can I re-use my existing onboard air?

Yes—pair your system with the HP10073 or similar horns; verify tank volume and compressor duty cycle.
