This Crossing Bell is a simple, fully self-contained sound module that plays a standard grade crossing bell sound. It has been specifically designed to be part of the Fully Integrated RR Crossing System from Dwarvin Enterprises.
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.
it is designed to be used with the Lamplighter™ FL animation unit as per the diagram below, together with train detectors (see Detector products). Just plug the output from the unit (the white wire) into the trigger port on the Lamplighter FL unit, and the Red and Black wires into the corresponding Power Output plug on the Lamplighter FL. To avoid soldering use the 8 Port Terminal Block for the Trigger inputs and the 2 Port Terminal Block for the power connections.
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.
The SoundBytes module needs 5-24 volts of clean direct current (DC) power to operate.
