SoundBytes Crossing Bell
(Western-Cullen-Hayes 777 (Electronic)

The SoundBytes Crossing Bell is a simple, fully self-contained sound module that plays a grade crossing bell sound.

FEATURES:
- Prototypical crossing bell sound
- Integrated speaker & volume control
- Easy to install and use
- Ideal for adding sound to grade crossings
- Powered from 5 to 24VDC

Note: Please do not use old model railroad power packs as a DC supply. These often produce large output spikes far in excess of their nameplate voltage ratings, are not suitable for powering modern electronics, and will damage SoundBytes modules.

Operation:
The SoundBytes module needs 5-24 volts of clean direct current (DC) power to operate. Connect the white wire to GND to activate the sound. Leave the white wire disconnected to turn the sound off.

Red Wire = 5V to 24V
Black Wire = GND
White Wire = GND to activate

The volume can be adjusted by using a small screwdriver to turn the white, square potentiometer on the PCB.
