AXIS A9910 I/O Relay Expansion Module for Door Controllers & Access Control

Model: AXIS A9910

Who This Is For

For access control integrators and facilities managers who need to expand the I/O capacity of an existing AXIS door controller installation without replacing the core hardware. The AXIS A9910 I/O Relay Expansion Module connects to compatible AXIS door controllers to add additional relay outputs and digital inputs, allowing a single controller to manage more doors, locks, request-to-exit devices, and alarm inputs than its native port count permits. This makes it well-suited to staged rollouts in commercial offices, educational campuses, and multi-tenancy buildings where access points are added progressively. Rather than commissioning a second controller for a handful of extra doors, the A9910 extends what is already in place - keeping the system architecture simple and the management interface unified.

What This Module Actually Does

Who Buys This Module

• Security integrators expanding existing AXIS installations: Adding controlled doors to a site already running a compatible AXIS door controller, without the cost or complexity of commissioning a second controller.
• Commercial facilities managers on phased fitouts: Office buildings or campuses where access control is rolled out in stages - the A9910 extends capacity incrementally as new areas come online.
• Educational and healthcare site managers: Institutions with multiple internal doors, alarm points, and REX devices that exceed the native I/O count of the installed AXIS controller.
• Multi-tenancy building managers: Properties adding access control to new tenancy spaces where the core controller is already in the comms room and additional I/O is needed for each new fit-out.

Honest Assessment

The AXIS A9910 does one thing well: it stretches the useful range of a compatible AXIS door controller by adding relay outputs and digital inputs at a lower cost and system complexity than deploying a second controller. For integrators managing phased or expanding AXIS access control installations, that is a practical and cost-effective answer to a common port-count problem. It keeps management unified and avoids fragmenting the system architecture. What the A9910 will not do is operate independently - it has no standalone access control logic and requires a compatible AXIS host controller to function. It is also not a starting point for a new installation; buyers without an existing AXIS controller should look at AXIS door controller products available through Security Australia as the first step. If the existing controller is not a compatible AXIS model, the A9910 is not applicable.

Before You Buy

Quick Fit Check

• Good match if: You have a compatible AXIS door controller already installed and need to control additional doors, locks, or supervised inputs beyond the controller's native port count.
• Good match if: Your site is being fitted out in stages and you need a low-complexity way to add I/O capacity incrementally while keeping system management in a single interface.
• You may need a different model if: You do not yet have an AXIS door controller on site - start with an AXIS network door controller as the foundation, and add the A9910 once the host is in place.

Real-World Scenarios

How It Compares

• Choose this if: You already have a compatible AXIS door controller installed and need more relay outputs or digital inputs without deploying additional controllers.
• You may need a different model if: You are starting a new installation from scratch - begin with an AXIS network door controller as the host unit, then add the A9910 for expansion once the core system is in place.
• Pairs well with: AXIS network door controllers and AXIS access control software for unified management of all doors and I/O points across the site.

Common Questions

1. Will the A9910 work as a standalone access controller without a host unit?

   No. The AXIS A9910 has no standalone access control logic and cannot function independently. It requires a compatible AXIS door controller as the host - the A9910 simply extends that controller's relay outputs and digital inputs. All access decisions, event logging, and management remain on the host controller.

2. Does this work with any brand of door controller, or only AXIS?

   AXIS only. The A9910 is designed specifically for use with compatible AXIS network door controllers. It connects via the I/O interface defined by AXIS and is not compatible with third-party controller hardware. Confirm your specific AXIS controller model is listed as compatible before ordering.

3. Can the A9910 drive electric locks and magnetic locks directly?

   Yes, via its relay outputs. The relay contacts switch the lock circuit on command from the host AXIS door controller. You should verify that the relay contact rating matches the current draw and voltage of the locking hardware being used - check the A9910 datasheet for relay specifications before wiring high-current lock hardware.

4. Does adding the A9910 require changes to the access control software configuration?

   Yes, the new I/O points added by the A9910 need to be configured in the AXIS access control software so the system recognises the expanded inputs and outputs. The process is managed through the same interface already used for the host controller - it does not require a separate software platform. Refer to the AXIS documentation for your controller model for the specific setup steps, available through Security Australia's technical resources.

5. How many A9910 modules can be connected to one AXIS door controller?

   The number of expansion modules supported depends on the specific AXIS door controller model in use. Each controller has a defined limit for expansion devices. Confirm this limit in the host controller's datasheet before planning a multi-module installation to avoid exceeding the supported configuration.

6. Will the A9910 support door position sensors and REX buttons on the same installation?

   Yes. The digital inputs on the A9910 can connect both door position sensors and request-to-exit buttons, along with other supervised contact devices such as alarm inputs. Each input reports its state to the host AXIS controller for event handling and logging, keeping all door monitoring centralised.

Cabling Considerations

• I/O Connection Cable: Use the cable type specified in the AXIS A9910 datasheet for the connection between the module and the host door controller - cable type and maximum run length are defined by the I/O interface standard used.
• Lock Wiring: Run appropriately rated cable to each electric lock or magnetic lock connected to the A9910 relay outputs. Factor in lock voltage and current draw when selecting cable gauge.
• Supervised Input Wiring: Door position sensors, REX devices, and alarm contacts connect to the digital inputs using standard 2-core screened cable. Keep input wiring separate from power and lock wiring to avoid interference.
• Power Supply: Confirm the power arrangement for the A9910 at its installation location, particularly if it is mounted at a distance from the host controller and if the relay outputs are switching hardware with a notable current draw.
