Features

• Simple to use
• Integrated speaker & volume control
  
• Ideal for adding sound to grade crossings
  
• Powered from 5V to 24V
• Turn off time = 5sec*

* the unit turns off 5sec after the Detectors no longer see a train.

Electrical Connections:

It is designed to be used with the Lamplighter™ FL animation unit.  Just plug the output from the unit (the white wire) into the trigger port on the Lamplighter FL unit, in conjunction with the Detectors, and the power into the power output on the unit. To avoid soldering, you can buy the 8 Port Terminal Block for the Trigger inputs and the 2 Port Terminal Block for the power connections.  Note:  The Lamplighter FL unit comes with a 6 JST plug connector set, unless the Terminal Blocks are ordered.  These require soldering to connect the Detectors to the Trigger inputs on the Lamplighter Flasher Unit. 

Red Wire = 5V to 24V

Black Wire = GND
White Wire = GND to activate (connect to the trigger port of the Lamplighter FL Animation unit with Detectors attached) 

When a train is detected the trigger units pull their output signals to round, this in turn activated the Bell. 

Additional information:

The bell needs 5-24 volts of clean direct current (DC) power to operate.
