CDVI Americas A22POE Atrium 2-Door PoE Controller w/ Enclosure & 60W Splitter

The A22POE is a two-door controller. Where it differs from a standalone two-door board is the Atrium platform behind it: an Atrium system scales to 500 doors by adding modules, so the two doors you wire today are the start of a system rather than its ceiling. Readers, keypads and Schlage wireless door handles all sit on the same system.

It ships as a PoE package: controller, enclosure, and a 60W PoE splitter. One Cat cable from a PoE switch or injector carries data and power to the panel, so you don't have to pull a separate 12V run to the closet. Lock power still has to come off the panel's outputs, and a 60W budget is what you're dividing between the board and the connected hardware.

No server, no license fee. The Atrium software is free, and the controller runs an embedded web server, so you point a browser on a laptop, phone or tablet at the panel and manage cards, schedules and reports from there. For a property manager running a handful of buildings, that means no PC sitting in a closet to keep alive.

Both are built around the CDVI Atrium 2-door platform and both are controller-with-reader access control products. The A22POE is supplied as the 2-door PoE controller with an enclosure and a 60W PoE splitter, so the panel is powered over the network run. The A22KITSTB is packaged as a 2-door kit that adds two STARPB readers and 15 credentials, so the reader hardware and starting card stock come in the box. Choose the A22POE when you already have readers and credentials on hand or are specifying them separately, and the A22KITSTB when you want the door-side hardware bundled with the panel.

The A22POE is a 2-door Atrium controller, so on a single-opening job half its door capacity sits unused. For a one-door application, the Schlage Electronics CTE ENGAGE single door controller with a mobile-enabled multi-technology reader is sized to one opening and connects by direct RS-485. The tradeoff is architecture: the CDVI Atrium platform is managed through its embedded web server from any browser, smartphone or tablet and scales to as many as 500 doors as you add modules, while the CTE unit is a single-door device on the ENGAGE platform. If the single door is the first of several planned, the 2-door A22POE leaves room to grow.

That is the case the CDVI A22POE is built for. It ships with a 60W PoE splitter and an enclosure, so the 2-door Atrium controller draws its power from the same network cable that carries data and no separate power run has to be pulled to the panel. The Schlage Electronics CTE ENGAGE single door controller, by comparison, is specified for a direct RS-485 connection back to the host, which is a wired data topology rather than a PoE one. Where the closet or ceiling location already has a switch port and nothing else, the A22POE removes the electrician from that part of the scope.

Yes. Atrium includes a user counter that lets you set the number of times a user may pass through a door or doors. That is the feature people reach for with trades, movers, or short-term access, where a card should stop working after a set number of entries rather than needing someone to remember to delete it.

Smart relays handle that. A relay on the Atrium controller can be set to follow a schedule, an input, or an output, or to fire for a set time period. That covers auto-unlock during business hours, tying a relay to an alarm or REX input, or momentary triggering of gate operators and auxiliary devices.

For a single opening with no plan to grow, a self-contained door controller is the simpler buy. The Schlage Electronics CTE ENGAGE Single Door Controller with mobile-enabled multi-technology reader over a direct RS-485 connection puts the controller and reader in one unit at the door. The A22POE makes more sense when you have two openings now, want them on one panel in one enclosure, or intend to add modules toward a larger Atrium system.

Both, plus wireless locks. Atrium supports proximity card readers, keypads, and Schlage wireless door handles on the same system, so a building can run cards at the main entrance and a keypad on a back-of-house door without a second platform.

No - they are not interchangeable at the panel. The CDVI A22POE is a 2-door Atrium controller managed through the Atrium embedded web server and free software, and the same Atrium head end supports proximity card readers, keypads and Schlage wireless door handles as you expand. The Schlage Electronics CTE ENGAGE is a single door controller with its own mobile-enabled multi-technology reader and a direct RS-485 connection, on a different management platform. Swapping one for the other means changing both door capacity and the software the site is administered from, so it is a system decision rather than a parts swap.

If the plan is to standardize, start on the CDVI Atrium platform. The A22POE is a commercial-rated 2-door controller, and Atrium scales to as many as 500 doors with proximity card readers, keypads or Schlage wireless door handles managed from one embedded web server using free software, with scheduling, user pass counters, smart relays and advanced reporting handled centrally. The A22KITSTB covers the same 2-door Atrium controller but arrives as a kit with two STARPB readers and 15 credentials, which suits the first building where no reader stock exists yet. For a single isolated opening that does not need to join the fleet, the Schlage Electronics CTE ENGAGE single door controller with an integral multi-technology reader is a self-contained alternative.

It is built and catalogued for commercial use. Two doors, PoE power, a 500-door platform and web-based reporting are aimed at multi-tenant, office and institutional openings rather than a single residential entry.

Atrium updates all modules at once. The .cuf and .pck firmware files push automatically to every module on the system rather than being loaded board by board, which is what keeps a multi-panel site on one firmware level without a truck roll per closet.

Yes. Atrium lets you add and assign a new card straight from the Events window tab, so an unknown card presented at a reader shows up in the log and gets enrolled from that entry. That saves reading numbers off the back of cards when you are handing out credentials on site.
