Hardware

AccessCore One. Four doors, one board, no server.

A networked door controller that makes access decisions at the door, connects straight to the cloud over Ethernet and is documented down to the terminal.

Architecture

Decisions at the door, not in the cloud.

  • Internet outage: doors keep granting and denying access locally. Connectivity is only needed to make configuration changes.
  • Updates and reboots: door I/O runs on a dedicated control processor, so doors stay in service while the node restarts.
  • Node offline: the control MCU keeps the door working from a master card list until the node returns.

Compliance

UL 294 compliant, with the installation conditions spelled out.

UL 294 is the safety standard for access control system units. A compliant install follows four conditions, and our documentation covers each one.

  1. Condition 1

    Locked enclosure

    The controller is mounted in a locked enclosure inside the protected premises.

  2. Condition 2

    Listed backup power

    Powered from a UL 294-listed access control supply with battery backup.

  3. Condition 3

    Fused lock outputs

    Locks are driven through a UL-listed fused relay/output board.

  4. Condition 4

    Independent egress

    Push-to-exit and fire-alarm release cut lock power in hardware, independent of the controller.
