ASSA ABLOY Aperio AH20-2-0 Gen 5 Advanced Wiegand Hub - 1:1 Interface (White)
The Aperio AH20-2-0 Gen 5 Advanced Wiegand Hub is the communication bridge between a single Aperio wireless lock or device and an existing Electronic Access Control (EAC) system. Like the Standard hub, it provides a 1:1 Wiegand interface - one hub per Aperio device - but the Advanced version adds four configurable relay outputs for extended lock status monitoring and low-level controller integration.
The hub communicates with the Aperio lock using 2.4 GHz encrypted wireless (IEEE 802.15.4, AES 128-bit) with a typical range of up to 25 metres depending on the building environment. For sites where credential pass-through alone is sufficient, see the AH20-1-0 Standard Wiegand Hub.
Special Order - estimated 1 month from order. Contact us to confirm current availability before ordering.
The Aperio AH20-2-0 is a restricted product that can only be sold to accredited installers. It is a special order item and is non-returnable unless faulty. Confirm system compatibility with your EAC integrator before ordering.
Key Features
- 1:1 Wiegand interface - connects one Aperio device to one Wiegand controller input on an existing EAC system.
- Four configurable relay outputs for low battery, door position, lock unlocked status, and lock offline status monitoring.
- AES 128-bit encrypted 2.4 GHz Aperio wireless communication (IEEE 802.15.4) between hub and lock.
- Real-time communication between hub and connected Aperio lock.
- Integrated antenna with option to connect an external antenna for extended range.
- Built-in tamper switch for physical security monitoring.
- Firmware upgrade capability to support future Aperio platform updates.
- LED status indication for installer commissioning and diagnostics.
- IP20 rated for indoor installation.
Advanced Hub Relay Outputs
The AH20-2-0 provides four configurable relay outputs, each mapped to a discrete lock status condition. These relay outputs enable the EAC controller to monitor the Aperio lock at a hardware level - beyond credential pass-through alone:
- Low battery status - signals when the connected Aperio lock battery is approaching end of life.
- Door position indication - signals door jamb / open or closed state.
- Lock unlocked status - signals when the lock has been granted access and is in the unlocked state.
- Lock offline status - signals when the lock has lost communication with the hub.
Relay output configuration is performed during installation and commissioning. Consult the Aperio Technical Catalogue and your EAC integrator for wiring and programming details.

Suitable Uses
- Higher-security sites where the EAC system must monitor lock battery level, door position, and lock offline state via relay inputs.
- Adding a single Aperio wireless lock to an existing Wiegand-based EAC system where extended status reporting is required.
- Installations where the controller needs discrete hardware-level signals rather than software-only status polling.
- Commercial and institutional deployments with stringent monitoring or audit trail requirements at the door level.

Model Comparison - AH20-1-0 vs AH20-2-0
Both models use the same encrypted wireless protocol and connect a single Aperio device to a Wiegand controller. The Advanced version adds four relay outputs and extended status monitoring.

Frequently Asked Questions
Choose the Advanced (AH20-2-0) when your EAC controller needs hardware relay signals for lock status - specifically battery level, door position, lock unlock state, or comms-lost conditions. If the controller only needs Wiegand credential data and your monitoring is handled at the software level, the AH20-1-0 Standard is sufficient and simpler to wire.
Each relay output maps to a specific lock status condition: (1) low battery alert, (2) door position (open/closed), (3) lock unlocked state, and (4) lock offline / comms-lost. These are discrete hardware signals wired to the access control panel - they allow the controller to trigger alarms, log events, or feed monitoring dashboards without relying on software polling.
The hub communicates wirelessly using the Aperio 2.4 GHz protocol (IEEE 802.15.4) with AES 128-bit encryption. This is not Wi-Fi - it is ASSA ABLOY's proprietary Aperio wireless channel. The hub then outputs credential data and relay status signals to the EAC controller via cabled connections.
One. The AH20-2-0 is a 1:1 hub - it connects a single Aperio lock to a single Wiegand controller input. For multi-lock deployments, one hub is required per lock. For higher-density integration, refer to the AH30 (1:16, RS485) and AH40 (1:64, IP/Ethernet) hub series.
The AH20-2-0 is rated IP20 for indoor installation only. Mount it on the secure side of the door - typically in a ceiling void, riser cabinet, or door frame area - within wireless range of the Aperio lock (up to 25 m free-air). Concrete, reinforced doors, and electrical interference reduce effective range. Confirm placement with a site survey before installation.
Additional Information
Standard vs Advanced — the practical decision: Most straightforward Aperio deployments use the AH20-1-0 Standard. The AH20-2-0 Advanced is specified when the EAC platform or site security policy requires hardware relay signals for monitoring. If in doubt, consult with your EAC integrator to confirm whether your controller supports and requires relay inputs from the Aperio hub.
Hub placement: The 25 m wireless range to the Aperio lock is a free-air maximum. Concrete walls, reinforced doors, and RF interference all reduce effective range. Hub placement should be determined during a site survey. Refer to the Aperio Technical Catalogue for placement guidance and antenna upgrade options where range is marginal.
Multi-lock deployments: For sites with more than one Aperio device, either deploy one AH20-2-0 per lock (each occupying one Wiegand input on the controller), or consider the AH30-3-0 (1:16, RS485) or AH40-4-0 (1:64, IP/Ethernet) hub series for more efficient multi-lock integration.
Professional installation required: This is an EAC infrastructure product. Installation, wiring of relay outputs, and commissioning must be performed by an accredited Aperio-trained installer. It is not suitable for end-user self-installation.
