What is the Access Expander?

The Connect ONE Access Expander is a hardware module that transforms your existing intrusion panel into a full-featured access control platform. It adds up to 90,000 users, mobile credentials, wireless locks, and advanced door management — all managed from one control panel and one unified interface.

Unified Integrations from One Control Panel

Compatible with ScanPass® Mobile Credential for 200+ access doors on one control panel.

Compatible with Assa Abloy Aperio Wireless Lock Technology for wireless access doors integrated into the same control panel.

Compatible with Cansec Systems MAP Access Controllers for additional access doors integrated into the same control panel.

Built-In Advanced Features

Always-on communication with no network configuration, no router setup, and no port forwarding required — ready to go right out of the box.

Multi-Factor Authentication, Virtual Anti-Passback, Configurable Door Prop and Door Forced Alerts, plus more.

Elk M1 — ACCEXP-M1

A common challenge with Elk M1 systems is the need to create individual rules for each permission scenario, along with limited scheduling flexibility. The Access Expander solves this by extending system capabilities to 90,000 users with flexible permission structures. Administrators can create system profiles that individualize permissions — by area for arming/disarming, and by door for access control. Each door supports up to four time windows with flexible holiday exceptions.

DMP XR — ACCEXP-XR

A common challenge with DMP XR systems is the requirement to group doors into areas for managing access permissions, which limits per-door control. The Access Expander removes this constraint by extending system capabilities to 90,000 users with individualized permission structures. Administrators can assign permissions by area for arming/disarming and by door for access control, with up to four time windows per door for precise scheduling.

Bosch B/G — ACCEXP-BG

The Access Expander adds ScanPass mobile credentials and Aperio wireless lock support to the existing Bosch panel infrastructure — extending access control capacity to 90,000 users without replacing or re-wiring the existing security system.

Honeywell Vista Turbo — ACCEXP-VT

The Access Expander brings ScanPass mobile credentials, Aperio wireless lock integration, and Cansec MAP controller support to the 128BPT and 250BPT platforms — delivering enterprise-level access control capabilities to an established and widely deployed panel family.
