This product system provides all that you need to integrate 2 Railroad Crossings together with 2 side-on Detectors and 1 crossing bell all controlled by the Lamplighter DFL unit.
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 5 seconds after all detectors return to their waiting state.
There is absolutely no programming nor soldering required. The 3 wires from the detectors and crossing bell are attached to the control unit using screws built into the control unit. It couldn't be easier.
The fibers are inserted into two "chimneys". Each can hold either a 1.0mm fiber for the HO RR Crossings or 0.75mm fiber for the N RR Crossings, or 1.5mm fibers for O RR Crossings.
When ordering the kit, select
- Either HO or N or O RR Crossings option, and
- Whether you want a power supply (9V) (extra cost of $8) or not (in which case you can use your DC bus from your layout which must be >7V with center positive wiring into the power jack connector provided in the kit) and you are done.
