Hello,I am about to install 2 Crossing gates with bulbs they are NJ Int. using Grade crossing pro.If you have had any expericence with this I could use your help.1. The crossing gates have 3 wires -2 with resistors and one black, where do they go on the GCP?2. Can I power the GCP with AC power? Can I use a power pack that has an AC connection for accessiores?3. What if I have DCC how would I power it that way?4. I have 2 ITT HQ Bell modules, how do I wire both to the GCP ( I have 2 speakers to go with them).Do you have a understandable wiring diagram for the novice?
Thanks
Drew
Didn't you get any documentation with the Grade Crossing Pro ? It's pretty self-explanatory on how to wire crossing signals.
Figure 3 shows where to wire bulb-based crossing signals, and the instructions also tell you what the voltage input requirements are for the GCP board.
If you need the documentation it can be downloaded from the Logic Rail Tech web site. Download the version for the detection type you're going to use.

The GCP requires an input of 7 to 9 volts AC or DC, so you should not try to power it from your DCC system's output, which should be around 14.5 volts. The AC accessory terminals on your power pack are 16 Volts, so they are way too high.
Drew - as the other gentleman said, the GCP should come with detailed instructions. I believe they too can be downloaded from their website. The person running the GCP website/product line was very helpful to me in setting up a crossing with three tracks.
Following the instructions to the letter - and the downloaded instrux from logicrail, I wired all this up and it worked like a champ - the first time - a rare occurrence for me! The resulting wire matrix looked hairy, but again, following the instructions carefully will almost surely guarantee success. I used Tomar lighted crossings (four LED's each), but your setup should be similar. If you are using the NJ moving gates, you will also need a pair of Circuitron Tortoises to supply the motion. This too is covered in the instructions.
Best of luck - I think you will enjoy the result.

If I can't use the AC off my accessory power pack, then what should I use to supply power??
Dick,
Drew,
Direct from the manual which I just got from the LogicRail website:
The GCP accepts AC or DC power (7 - 16V). Power consumption when used with LED-based signals is approximately 90mA; power consumption when using bulb-based signals is approximately 130mA. If you are only using a single GCP then use the TWO AC terminals to provide power (polarity doesn’t matter); do NOT connect AC power to the GND terminal! You can use the AC or DC accessory terminals on your throttle/power pack provided the voltage doesn’t exceed 16V. You can even power the circuit from the rails if you’re using command control (e.g. DCC, Railcommand, etc); in this case use the AC IN terminals on the GCP. If you are using more than one GCP you can power them all from a single DC source as shown in Figure 7 below.
