Dear PWRS Customers;

Circuitron is excited to add a New Accessory

Circuitron BR-3 Digitally Recorded Grade Crossing Bell With Speaker Circuitron Item #: 800-5703

Overview:

Although CIRCUITRON has had their BR-1 mechanical doorbell ringer for decades, they felt it was time to offer a more realistic option for grade crossings. Working with Circuitron 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 Circuitron 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.

GD-1 Gate Driver Circuit

The GD-1 Gate Driver circuit, when used with a CIRCUITRON TORTOISE train detection circuitry such as their DT-1, DT-2 or DT-3, an alternating flasher circuit such as their FL-2 and a bell ringing circuits such as their BR-1 & BR-3 will provide all the control electronics for a gate protected grade crossing.

The GD-1 can drive one or two TORTOISE machines. With the addition of Circuitron's 8100 Remote Signal Activator, the TORTOISE will be able to control crossing gates in any scale that use a vertical control wire through the layout base. The GD-1 is designed to be powered by 8-20 volts DC. The speed of the TORTOISE is adjustable and can be set to lower the gates at the proper (desired) speed. In addition, an adjustable Gate Delay trimmer (0—6 seconds) allows an initial time delay before the gates start to move. The Bell and Flasher outputs will be ON during this delay. The input control terminal needs less than 1 ma for actuation, thus requiring a negligible drive current from the controlling circuit. Inputs to the GD-1 must be a ground signal.

There are both Flasher and Bell outputs which provide a grounded output to control external devices. The Flasher output has an adjustable Hold control which can be used to hold the flasher circuitry on while the gate rises so that they shut off together. Both the Flasher and Bell outputs can control up to 250 ma. The GD-1 Gate Driver Circuit is constructed on a 2” x 3” circuit board.
