CDVI A22K1TB – Frequently Asked Questions

1) How many doors and readers will the CDVI Atrium A22K controller run?
The A22K controller in the A22K1TB kit handles 2 doors and 4 readers, with an entry and exit reader per door port. User capacity is 10,000 users and 10,000 cards, with a 25,000 event buffer, so it scales well past the two openings it starts on. The kit ships with the A22K controller, K1 Krypto readers and TAG-EV2 credentials, so a two-door install is covered out of the box.
2) What credential technology does the CDVI Atrium A22K1TB kit read, and will my existing prox cards work?
The K1 Krypto reader supplied in the kit reads 13.56 MHz MiFare Classic and DESFire EV1/EV2 credentials, and the badges included are TAG-EV2 MiFare DESFire EV2 4k. The A22K controller itself is a hybrid: it accepts common Wiegand card readers as well as the Krypto high-security readers. So 125 kHz prox cards will not read on the K1, but if your existing readers are Wiegand you can wire them to the controller and keep the credentials you already issue.
3) How far can I run the reader and controller wiring on the Atrium A22K?
The K1 readers connect back on a fully secure RS-485 link, and the A22K's on-board RS485 communication bus is rated to 1220 m (4000 feet), which is what governs how far you can push devices from the controller. Readers need 12 VDC. The K1 also carries an operating range of -13F to 140F, so an exterior door in a cold climate is within spec.
4) Does the CDVI Atrium A22K need a server or subscription software to manage users?
No server and no separate license. The A22K runs an embedded secure HTTPS web server, so you manage it from a browser on a phone, tablet or PC over an encrypted connection, and the Atrium software is free. The Ethernet port uses AES 256-bit encryption and the controller is IPV6 ready. For a property manager with a handful of buildings, that means adding and deleting cards without a workstation on site.
5) Only one door needs access control - is there a smaller option than the A22K1TB Atrium kit?
For a single opening, the Schlage Electronics CTE ENGAGE single door controller with mobile-enabled multi-technology reader and direct RS-485 connection is a one-door controller-with-reader package. The A22K1TB Atrium kit is sized differently: its A22K controller handles two doors and four readers, with entry and exit per reader port, two lock outputs at 750 mA @ 12 VDC each, two Form C dry contact relays, and six multi-purpose inputs that become twelve with zone doubling. If the site has one door today and no second opening planned, the CTE covers one door; if the second reader position or an exit reader is coming, the A22K1TB already carries the capacity.
6) What is the read range on the CDVI K1 Krypto reader, and how big is it for mullion mounting?
The K1 reads up to 2 inches (5 cm) and measures 1.65 x 5.5 x 0.91 inches, a narrow footprint that suits a mullion or a narrow stile beside a glass front door. It is OSDP-2 compatible, so it fits a specification calling for OSDP rather than Wiegand at the reader.
7) Can I use the CDVI Atrium A22K for elevator floor control instead of doors?
Yes, and without buying different hardware. Any A22K door controller converts to an A22KEC elevator controller by updating the firmware, free of charge, supporting up to 256 floors. That matters on a mixed job where an opening turns into a cab call later, or where a residential tower needs floor restriction on the same head end running the entry doors.
8) How many inputs does the A22K have for request-to-exit and door contacts?
Six multi-purpose inputs on board, expandable to 12 using zone doubling. Across two doors that covers REX and door position contact on each, with spares for tamper or an auxiliary alarm point. The system is entirely fuseless and uses snap-on terminal connectors, so a board swap does not mean re-terminating every wire.
9) What is the difference between the CDVI A22K1TB kit and the A22KITSTB kit?
Both are Atrium 2-door kits built on the same A22K controller with 15 credentials. The difference is the reader: the A22K1TB comes with the K1 Krypto high-security reader, while the A22KITSTB kit ships with the STARPB reader instead. Pick on the reader style and mounting you need at the door, since the controller, capacity and management software are the same either way.
10) Should I buy a 2-door Atrium kit or a single-door controller like the Schlage CTE?
It comes down to how many openings and whether you want the reader and controller in one piece. The Schlage Electronics CTE ENGAGE is a single door controller with a mobile-enabled multi-technology reader on a direct RS-485 connection, so it is a one-opening solution. The CDVI A22K1TB kit is a head end that runs 2 doors and 4 readers with 10,000 users, so it is the better start if there is a second door now or a third door coming.
11) Which access control kit suits a facility that wants high-security encrypted credentials at the reader rather than standard proximity cards?
The A22K1TB Atrium kit ships with the K1 Krypto high security card reader and the TAG-EV2 MiFare DESFire EV2 4k badge, and the A22K controller is a hybrid that accepts popular Wiegand card readers or the Krypto high security solution. The K1 talks to the controller over a fully secure RS-485 connection and is OSDP-2 compatible, and the TAG-EV2 measures 1.75 in. x 0.5 in. x 0.08 in. at 13.56 MHz. The alternate CDVI kit, the A22KITSTB, is the same two-door Atrium controller with 15 credentials paired to STARPB readers instead. Both are controller-with-reader kits for commercial electronic access control.
12) Can the Schlage CTE ENGAGE controller replace an A22K1TB Atrium kit on a two-door job?
The CTE ENGAGE with mobile-enabled multi-technology reader is a single door controller, so a two-door opening set is a different scope of hardware than one CTE. The A22K1TB centers on the A22K controller, which runs two doors and four readers from one board, holds up to 10,000 users and 10,000 cards with a 25,000 event buffer, and is managed through an embedded secure HTTPS web server over an Ethernet port with AES 256-bit encryption. It also carries an on-board RS485 bus rated to 4000 feet and can be converted to an A22KEC elevator controller for up to 256 floors by a firmware update. Buyers standardizing a building on one head-end usually compare at the controller level first and choose the reader afterward.
13) Is the CDVI A22K1TB Atrium kit suitable for a commercial building or only residential?
It is a commercial-rated access control package, and CDVI positions the A22K for both commercial and residential use. For an MRO or institutional buyer the practical points are the 10,000 user and card capacity, the 25,000 event buffer for audit history, and AES 256-bit encrypted IP communication rather than an open network link.
14) What size are the TAG-EV2 badges included with the CDVI Atrium kit?
The TAG-EV2 key fob measures 1.75 in (45 mm) x 0.5 in (13 mm) x 0.08 in (2 mm), small enough to sit on a keyring without bulk. It is a 13.56 MHz DESFire EV2 4k credential, and CDVI supplies it in packs of 25 when reordering beyond the credentials in the kit.
