Dwarvin HO IRRXK301 DV Integrated Crossing Signal Kit

The Dwarvin Integrated Crossing Signal Kit from provides all that you need
to integrate two railroad crossings together with two side-on detectors and
one crossing bell, all controlled by the Lamplighter The detectors are of
the pulsed infrared kind so they are insensitive to the ambient lighting.

They stay on as long as they "see" an object.
The DFL unit, in turn, turns
off five seconds after all detectors return to their waiting state.
There
is no programming or soldering required.
The three wires from the detectors
and crossing bell are attached to the control unit using screws built into
the control unit.
The fiber optics are inserted into two "chimneys".
Each
can hold either a 1.0mm fiber for the HO Scale crossings or 0.75mm fiber
for the N Scale crossings, or 1.5mm fibers for O Scale.
Integrated Crossing
Signal Kits are supplied with or without power supply.
They can also be
powered from your layout bus with center-positive wiring into the power
jack connector provided in the kit.
Note: Each track must have its own set
of detectors for the crossing signals to function.
The Dwarvin Integrated
Crossing Signal Kit is one of many fiber optic lighting and signaling
products from Dwarvin.
