Expand the capabilities of your Dahua intrusion alarm system with the Dahua DHI-ARM808-RS, a highly reliable 8-zone alarm input expansion module. Designed to seamlessly integrate with Dahua ARC series control panels (including ARC3008C, ARC9016C, ARC2008C, and ARC2016C), this compact module adds 8 additional alarm input channels and 2 alarm output channels to your security infrastructure.


The DHI-ARM808-RS offers exceptional flexibility with DIP switch address setting and configurable End-of-Line Resistor (EOLR) values (2K7, 4K7, and 6K8). It supports multiple zone termination types, including NC, NO, 1EOL, 2EOL, 3EOL, INERTIAL, and IMPULSE, ensuring compatibility with a wide range of third-party sensors and detectors. The alarm outputs can be easily configured as Normally Open (NO) or Normally Closed (NC) via onboard jumpers, with an output capacity of 30 VDC / 500 mA.


Communication is handled via a robust RS-485 interface, supporting cable runs of up to 300 meters (using RVV2*1.5 cable). Powered by a standard 12 VDC supply and consuming only 1.2 W, this ultra-compact module (90.0 mm × 62.0 mm × 12.6 mm) is designed for discreet installation inside control panel enclosures. With support for remote firmware updates via client software, the Dahua DHI-ARM808-RS ensures your security system remains scalable, up-to-date, and ready for any expansion needs.
