Please note: Professional installation recommended.

Below you will find installation diagram that is applicable to most 12V setups and a basic installation procedure if you wish to install the kit yourself.

Before DIY Install

  • Roughly decide where each component of the kit will be mounted
  • Make sure there is enough wire and space to safely and professionally install the kit
  • Keeping the supply wire to compressor as short as possible maximizes efficiency

Installing Horns

  • Locate safe and secure area for train horns
  • Drill mounting holes for each horn mounts
  • Secure horn using mounting hardware and double check fittings

Installing Air Compressor

  • Disconnect battery cable from vehicle
  • Place air compressor in a secure area up right or horizontally
  • Install air compressor assembly
  • Mount air compressor where it will be exposed to air flow
  • Mount air compressor upright or horizontally (DO NOT mount upside down)
  • Mount air compressor above air tank
  • Use teflon tape on all fittings to ensure a 100% seal

Installing Air Tank

  • Make sure hose to compressor to air tank is suitable length
  • Position tank in desired location and secure it with mounting hardware
  • Mount tank away from windows and out of the way of high traffic areas

Installing Tubing

  • Double check all measurements before cutting and fitting tubing
  • Leave approx. 1 inch extra per air line as precautionary measure
  • Use teflon sealant to secure all fittings and prevent air leaks
  • Check for any kinks or obscurities in the tubing after installation
  • Connect air compressor to air tank, secure all connections
  • Connect pressure switch to tank using teflon sealant
  • Connect air tank to air valve, then valve to horn, using teflon sealant
  • Make sure to properly cut tubing and use appropriate fittings

Troubleshooting – Q & A

Q: Why won’t my air horn make a sound?
A: Check air tank is pressurized, make sure switches are on, replace fuses, check all electrical circuits are secure

Q: Why does the sound of my horn change?
A: Ensure the air source from valve is entering the proper manifold, check each air line is equal length

Q: Why is there so much moisture in the horn?
A: Depressurize tank, drain tank, move compressor to area of less humidity

Q: Why isn’t my Compressor running?
A: Check switches, replace fuses, replace pressure switch

Q: Where is the excessive knocking coming from?
A: Move compressor to cooler area, replace air compressor

Routine Maintenance

  • Check for debris and clean horn and kit monthly
  • Drain air system at least once a month to remove condensation
  • Change air filter periodically
  • Make sure engine is running to ensure proper voltage
  • Wiring: Check installation diagrams for wiring instructions

Safety Tips

  • Do not disassemble the preassembled electrical components of the kit
  • Do not try to repair any electrical connections yourself without professional supervision
  • Do not operate near water
  • Do not touch any wet components
  • Use the kit only with a 12v DC Charging system
  • Never leave the kit unattended during use
  • Children should never operate system
  • Beware of extreme heat from air compressor during use
  • Do not use kit around open flames
  • Do not operate horn near humans
  • Use only in well ventilated areas
