Grade Crossing
Controller with Bell Sound

(item #587)


Make your intersection come alive with the Grade Crossing Controller with bell sound.  This unit features full synchronization of the crossbuck lights and bell with four user selectable speeds including either simultaneous or delayed bell.  The Grade Crossing Controller with bell sound sound can be turned on either manually with a switch or automatically with it's unique built in current sense detection circuitry.  For precise operation, you can use our OPTO­DT to activate the switch input.  The Grade Crossing Controller with bell sound features four outputs.  Two outputs for your crossbuck lamps or LED's.  The other two outputs are to drive a coil or relay for crossing gate operation and an additonal output simulates a warming fire in a can or stove for the gate operator.  The later two outputs can also be switched to momentary drives for activation of a twin coil solenoid, if that is what you have elected to use to drive your gates.  For better realism we suggest using slow motion switch machines.

A three inch speaker is included and volume is user adjustable.

The Grade Crossing Controller with bell sound is completely assembled, except for the speaker enclosure, on a 5.75 X 2.75 inch circuit board which has standoffs at the four corners for easy mounting.  Wiring for the automatic detection circuit is accomplished by insulating a section of rail with gaps, fibre pins or plastic rail joiners.  In three rail applications it is suggested that the center rail be used for simplicity.  This insulated rail section is now electrically dead and must receive power from an additional wire attached to the power source or to the adjacent rail sections.  This additional wire must be passed through the hole in the "SENSE COIL" before being attached to the insulated rail section.

Input power can be from 14 to 20 volts AC or DC.
