SDC FB-4 – Frequently Asked Questions

1) What does the SDC FB-4 power distribution module actually do in an access control system?
The FB-4 takes the primary DC output from an SDC 600 series power supply and splits it into four individually fused Class 2 outputs, so each locking device or reader gets its own protected circuit. Each output carries a 2 amp fuse and its own on/off switch, plus an LED status indicator. That means you can kill power to one strike or mag lock for service without dropping the rest of the system.
2) Do I have to order a 12VDC or 24VDC version of the FB-4?
No, there is only one version. The FB-4 is auto-sensing 12/24VDC, so the same module works on either supply voltage without jumpers or a different part number. It is offered as a single model, FB-4.
3) I need more than four fused outputs. Can I add FB-4 modules?
Yes. The FB-4 is stackable in that sense: four modules off one 600 series supply give you sixteen individually fused outputs total. Each added module brings its own four 2 amp fused circuits with their own switches.
4) Is the FB-4 a power supply or does it need one?
It is a distribution board, not a source. The FB-4 has no transformer or battery charger of its own; it takes the primary DC output from an SDC 600 series power supply and divides it. You still need to order the supply that feeds it.
5) Will the FB-4 fit inside my existing power supply enclosure?
The board footprint is 3.3 x 2 inches, which is small enough to mount in tight spaces and standard electrical enclosures. Measure the free area in your cabinet against those two numbers before you commit to an in-can mount.
6) How much current can each FB-4 output supply to a mag lock or strike?
Each of the four outputs is fuse protected at 2 amps, so size your device load under that per circuit. If a single lock draws more than 2 amps inrush or holding, put it on its own supply rather than a shared FB-4 output.
7) Is the FB-4 rated for low voltage Class 2 wiring in a commercial building?
The four outputs are Class 2, which is what inspectors look for on low voltage access control runs in commercial work. The module is a commercial-duty device, not a residential accessory.
8) Why use a fused distribution module instead of just splicing several locks onto one supply output?
A shared splice means one shorted strike takes down every device on that circuit. With the FB-4, each of the four outputs is separately fused at 2 amps, so a fault isolates to that one leg. The per-output switches and LEDs also let a tech troubleshoot a single opening without shutting down the whole system, which is the difference that matters on a multi-door job.
