Access control enclosures usually need two voltages. The controller and the locks may want 24 VDC while readers, REX devices and maglocks want 12 VDC. The ADC-AC-B100 takes the 24 VDC coming off the main supply and delivers a clean 12 VDC leg at up to 4 amps, so a single enclosure covers both without a second transformer and a second AC run.
Built for the commercial installer
In an Alarm.com Aero deployment the board sits between the FPV4 power supply and the F8 distribution module, converting the supply output down so the distribution module can hand out both voltages. Because it is fed from the main supply rather than its own transformer, everything downstream stays on the same backup battery, and one power failure behaves predictably across the whole enclosure.
Keep the upstream supply set to 24 VDC. Dropping the FPV4 to 12 V leaves the B100 and the F8 distribution module with 12 VDC or lower, which removes the second voltage rail the enclosure was designed around.
Key features
- Adds a 12 VDC rail to a 24 VDC enclosure, so one cabinet powers both controller and door hardware
- 4 amps of headroom covers multiple readers, strikes and REX devices off a single board
- Fed from the existing supply, which keeps all downstream loads on the same backup battery
- Board-level mounting inside the access control enclosure, no separate can or AC circuit
System requirements
Requires a 24 VDC source, typically the FPV4 power supply in an Alarm.com Aero access control enclosure. The upstream supply must remain configured for 24 VDC output for the board to deliver its 12 VDC leg.
