The Speco A2E4 is a two-door access controller from the Speco Access range, expandable to four doors when used with the A2M expansion board. It is managed from any browser, runs an embedded Linux operating system, and is ETL-listed in accordance with the UL-294 standard for Access Control System Units. This is the basic-power version; the A2E4P is the same controller supplied as a power package.
Model: A2E4 | Capacity: 2 doors, expandable to 4 with the A2M board | Management: Browser-based, works in all browsers | Operating System: Embedded Linux | Protection: ETL-listed to UL-294
The controller ships as a two-door unit but is built to take the A2M expansion board, which adds two more doors with their own readers, relays and inputs. That matters at specification time: a site that may grow past two doors can start on this controller rather than being replaced later.
This is the basic-power variant — the A2E4P supplies the same controller as a power package. An installation manual, quick start guide and wiring diagram are published for both.
