## Summary description

DAHUA ARM808-RS is an access control expander module providing 8 inputs and 2 outputs for integration with security and access control systems. Designed to extend I/O capacity of DAHUA controllers, it enables additional sensor, door contact and alarm connections, facilitating centralized management and event-triggered responses in commercial or residential installations.

## Long description

DAHUA ARM808-RS is an access control expander module that provides eight inputs and two outputs to extend the I/O capacity of compatible DAHUA controllers. It is intended for integration with access control and security systems to add connection points for sensors, door contacts and alarm devices. The module supports centralized event handling and helps route signals from multiple doors or detectors back to a main controller for processing.
Advantages
The expander increases the number of available inputs and outputs without replacing the main controller, allowing system growth while keeping existing infrastructure. Its compact design simplifies installation in control cabinets or equipment racks and reduces the need for separate relay modules. By providing additional inputs and outputs close to doors or sensor clusters, the module can reduce wiring complexity and improve response times for event-triggered actions.
Suitable for
Commercial office buildings requiring additional door sensors or alarm inputs
Residential complexes that need extended I/O for multiple entry points
Retail and facility environments with numerous sensors or auxiliary devices
Upgrades to existing DAHUA access control systems where extra inputs/outputs are needed
When it may not be suitable
This expander is intended specifically to complement compatible DAHUA access controllers; it is not a standalone access controller and cannot operate independently as a full access management unit. Installations that require integrated user management, reader interfaces or networked controllers must retain or deploy the appropriate main controller to use this module.
Key specifications
Inputs: 8 configurable inputs for sensors and door contacts
Outputs: 2 relay outputs for locks, alarms or auxiliary devices
Form factor: compact module suitable for mounting inside control cabinets
Integration: designed to extend I/O capacity of compatible access controllers
Signal types: dry contact compatible inputs and relay-type outputs
How to use
Mount the ARM808-RS module in the control enclosure near the devices it will serve, and connect sensor and door contact wiring to the input terminals. Connect the outputs to locks, sirens or other actuators using the relay output terminals. Integrate the module with the main DAHUA access controller according to the controller's expansion interface procedure and configuration settings. After wiring and powering the system, configure input types and output behaviors in the controller software so events are registered and appropriate actions are triggered.
What to consider before purchase
Confirm compatibility with your existing DAHUA access controller model and expansion interface
Verify required input/output types (dry contact, relay) match your sensors and actuators
Check available mounting space and wiring distances to ensure proper installation
Ensure your controller firmware and software support additional expander modules
Usage recommendations
Place the expander close to the cluster of sensors or doors it will serve to minimize cable runs. Test each input and output during commissioning and document wiring to simplify future maintenance or expansion.
