Answer/Steps

  1. Verify the facility has TISSOT high voltage relay box.  This box will be between the Tissot stanchion box and Tissot's 120V buzzer.​
  2. Disconnect the current TISSOT buzzer and remove from it’s current location.
  3. Route the current TISSOT horn power cable to the new location.
  4. Locate the Daktronics Horn Assemblies.
  5. Remove the 8 screws and open up the horn enclosure

  6. Using a pliers pinch the strain relief to remove the cable from the back of the enclosure. Also remove ground wire from the ground terminal.

  7. Using the strain relief from the cable removed from the Daktronics horn enclosure secure the TISSOT horn power cable into the back of the Daktronics horn enclosure. This cable is smaller in diameter so using black electrical tape wrap the end of the cable approximately 20 times at the point where the strain relief will grip the cable.
  8. Connect the Green ground wire to the ground terminal.
  9. Cut the terminal off the power wires and strip the insulation back about an inch.

  11. Wire nut the horn wires to the power wires coming into the enclosure. Black to black and white to white. Using electrical tape wrap the wire nuts for added security that will avoid the wire nuts from loosening up.

  12. Re-assemble the horn enclosure with the 8 screws removed earlier.
  13. Mount the horn in the location shown above: ​
    1. Place horn in​ desired location with approximately a​ 20 degree downward slope.
      1. ​Make sure you mount the horn at least 1” above the bottom of the stanchion in order to give enough clearance for the pads when the stanchion is down. ​
    2. Mark mounting holes through the holes provided in the mounting bracket on the horn enclosure. 
    3. Using a ¼ - 20 Drill and tap bit drill two mounting holes at the marked locations​. 
      1. If desired self tapping screws could be used here as well but this approach would allow for a more secure mount. 
    4. Using corresponding bolts secure the horn to the stanchion. 
      1. Depending on the hardware used you will more than likely need to enlarge the holes on the horn enclosure mounting bracket to accommodate the necessary hole size. ​
