Device Type: M-Bus 8-Zone Expansion Module (Wired Alarm Accessory)
Model / SKU: DHI-ARM808 (also listed as DH-ARM808 / ARM808)
Zone Expansion: Adds 8 additional wired zones to a compatible Dahua alarm control panel; supports both Normally Open (NO) and Normally Closed (NC) detector inputs
Alarm Outputs: 1-channel alarm output (relay output)
Communication Protocol: M-Bus (dedicated bus protocol for Dahua alarm panels); baud rate 9600 bps
Compatibility: Specifically designed for and applied in the Dahua ARC9016C-V3 alarm controller
Power Supply: 12 VDC, 2 W; M-Bus bus-powered — no external power supply required
Transmission Distance: M-Bus line up to 2.4 km (approx. 7,874 ft)
Maximum Cascade: Up to 30 modules can be cascaded on the same M-Bus line
Surge Protection: M-Bus signal line common-mode ±2 kV, differential-mode ±1 kV
Physical & Installation: Dimensions 136 mm × 132 mm × 30 mm (5.35" × 5.20" × 1.18"); Weight 0.6 kg (1.32 lb); Wall-mount installation
Key Specs: Dahua DHI-ARM808 M-Bus expansion module, 8-zone expansion, 1-channel alarm output, M-Bus protocol, 9600 bps, 12 VDC/2 W, bus-powered (no external PSU), 2.4 km transmission distance, up to 30 modules cascadeable, wall-mount design, specifically engineered for ARC9016C-V3 control panels
Usage: Extending the zone capacity of Dahua ARC9016C-V3 wired alarm systems in residential, commercial, and industrial installations where additional detection points (PIRs, door contacts, glass-break detectors, etc.) are required beyond the panel's onboard zone count; the single alarm output can be used for local sounder, strobe, or auxiliary signaling.
