Command Access VD2-873 – Frequently Asked Questions

1) Will the Command Access VD2-873 board mount in a Von Duprin PS873 power supply without modification?
Yes. The VD2-873 relay board mounts to the Von Duprin PS873 in the same fashion as the factory original PS871-2 board, so the existing mounting locations in the enclosure are used as-is. It was built with similar characteristics to the PS871-2, which is what makes it a drop-in when the original board is no longer available.
2) My Von Duprin PS871-2 relay board failed and I can't get one anymore. What do I use instead?
The Command Access VD2-873 is the replacement for that situation. It's built for PS873 power supplies whose original PS871-2 boards are no longer available, mounting the same way and carrying similar characteristics to the original. You keep the existing PS873 enclosure and transformer and swap only the board, so the access control installation stays in service instead of being replaced outright.
3) How many outputs does the Command Access VD2-873 relay board give me, and can it prioritize one input over another?
Two I/Os, with priority sensing. That means the board can resolve competing signals rather than acting on whichever arrives first, which is what you need when a fire alarm or free egress input has to override a card reader or request-to-exit command on the same supply. Two I/Os covers a pair of controlled openings, or one opening with two control sources.
4) Will the Command Access VD2-873 work in a Von Duprin PS902 or PS914 power supply?
No. The VD2-873 is cut for the PS873 and mounts the way the PS871-2 board did in that enclosure. It is not the board for a different Von Duprin supply chassis. Identify the model stamped on your power supply before ordering, and if it is not a PS873, this is not the replacement board for it.
5) Is the VD2-873 a mechanical relay board or solid state?
Solid state. There are no mechanical relay contacts to pit, weld, or wear out from cycling, which matters on high-traffic openings where an electric strike or exit device trim is being switched hundreds of times a day. It's the main functional difference from an older mechanical relay board doing the same job.
6) What kind of wire terminations are on the Command Access VD2-873 board?
Euro style connectors, the pluggable screw-terminal blocks. Practically, that means you can land your field wiring on the removable plug at the bench or in the can, then seat it on the board, and you can unplug a circuit later for troubleshooting without pulling conductors out of a terminal. Worth knowing before you're on a ladder with the enclosure open.
7) Do I have to order a specific version of the VD2-873, or is there only one?
One model, VD2-873. There are no finish, voltage, or configuration options to specify on the order, so the part number is the whole selection. Just confirm the supply you are working on is a Von Duprin PS873, since that is the enclosure this board is cut to fit.
8) Is the Command Access VD2-873 relay board rated for commercial buildings or is it a residential part?
Commercial. It is a door hardware access control component intended for commercial power supply systems, and the applications it is built around are commercial buildings, schools, healthcare facilities, retail, industrial and government access points, plus legacy system modernization where discontinued factory boards need replacing.
