Aiphone ACS-2DR-C - Access Control Starter Kit

The ACS-2DR-C is a 2 to 8 door master controller kit. Out of the box it handles two doors, using the included AC-C master door control board and a two-door relay control board inside the enclosure. To get past two doors you expand with additional AC-2DM modules and AC-2DR panels on the same AC Series system.

Each door on the kit has two dry contacts and one wet contact for door release. Contact rating is 30V DC 1A, and lock/option power is 12V DC at 500mA. That 500mA figure is the number to check against your strike or maglock draw: anything hungrier needs its own power supply switched through the dry contacts rather than pulling from the board.

Yes. The kit is listed to UL 294 and ULC 5319-05, which is the access control system units standard. That matters if your AHJ or insurer requires listed equipment on egress or fire-related openings.

No separate server PC is required to program it. The AC Series system is managed through AC-NIO management software and configured with browser-based programming, with partitioning available if you need to split control between tenants or departments. Credentials and history live on the hardware: it stores up to 100,000 credentials and 50,000 events locally.

The ACS-2DR-C is built around browser-based programming and AC-NIO management software, so it expects a network connection to configure and administer. If the opening has no network drop, a standalone controller such as the Codelocks A3 dual door controller with RFID handles two doors without a management server behind it. The tradeoff is the expansion path: the Aiphone kit scales from 2 to 8 doors on the master controller and accepts additional AC-2DM modules and AC-2DR panels as part of a larger AC Series system, which a standalone dual controller does not do.

The relay board runs on 12V DC drawn from the main board, so you are feeding one 12V DC supply into the panel rather than powering each board separately. Keep lock current off that same budget if your hardware exceeds the 500mA lock/option allowance.

For one or two openings with no network management, a panel kit of this size is more than you need. A standalone controller like the Codelocks A3 dual standalone door controller with RFID handles two doors without software or a network. Go with the ACS-2DR-C when you want centralized credential management, an audit trail, and room to grow to eight doors on one enclosure.

Yes. It works on its own as a starter panel or as part of a larger AC Series system alongside additional AC-2DM modules and AC-2DR panels, all administered from AC-NIO.

No. The Codelocks A3 is a standalone dual door controller from the A3 Door Controllers series and is not an AC Series component. The ACS-2DR-C kit is expanded with Aiphone AC-2DM modules and AC-2DR panels, and its two-door relay control board works with the AC-C master board supplied in the kit, where each door gets two dry contacts and one wet contact for door release at 12V DC. If you are adding doors to an existing AC Series head end, stay within the Aiphone AC Series modules rather than substituting a standalone unit.

It is a commercial-grade product. The steel lockable enclosure, conduit knockouts, UL 294 listing, and the 100,000 credential capacity point at office, multi-family, school, and healthcare use rather than a single residence.
