Circuitron ~ BR-3 Digitally Recorded Grade Crossing Bell With Speaker ~ 5703

Although CIRCUITRON has had their BR-1 mechanical doorbell ringer for decades, we felt it was time to offer a more realistic option for grade crossings. Working with our friends at Iowa Scaled Engineering, the BR-3 is the result. Containing all the circuitry AND miniature speaker in a special design 3D printed enclosure, the BR-3 faithfully reproduces the ring of a typical mechanical grade crossing bell. It is FAR more realistic than our BR-1 and costs less because the pricey mechanical
doorbell is not needed.

Measuring just 1.19” square by about 1.25” high, the BR-3 module is small
enough to fit in many trackside structures. If no structures are located close to the grade crossing, the module can be mounted below the layout with the sound port projecting into a hole up through the layout. A model bush can be used to disguise the hole topside. The BR-3 requires a 8-18 volt AC or DC (DC is preferred) power supply and it has a white control wire that will connect to the out-
put of any CIRCUITRON (or other brand) detection circuit as long as the output provides a connection to GROUND [-] when the train is detected.

The BR-3 can also be manually controlled with a panel switch. The BR-3 module contains a volume control to adjust the output level.
