Adds 8 more wired detector zones and 2 outputs to a Dahua wired alarm panel, and can sit near the detectors to keep cable runs short. Bare board on the RS-485 bus, up to 300 m from the panel; for ARC2008C-V3, ARC2016C-V3 and similar panels.

Overview
The Dahua ARM808-RS is an input expansion module for Dahua wired alarm control panels. It is a bare circuit board that joins the panel’s RS-485 bus and adds 8 more detector zones plus 2 alarm outputs. It suits a building that needs more zones than the panel board provides, or one where a group of detectors sits far from the panel: placed near the detectors, it keeps their cable runs short, with only the bus cable going back.
Is it right for you?
- It suits a Dahua wired panel such as the ARC2008C, ARC2016C, ARC9016C or ARC3008C that has run out of zones.
- The ARC2008C-V3 and ARC2016C-V3 panels take up to 8 of these modules.
- It is an open board, so it must be mounted inside the panel cabinet or in a separate enclosure.
- If you need more outputs rather than inputs, the ARM708-RS is the matching output module.
Key features
- 8 alarm inputs and 2 alarm outputs.
- Zone wiring: NC, NO, 1EOL, 2EOL and 3EOL (end-of-line resistor), plus inertial and impulse types on the ARC3008 panel.
- End-of-line resistor values of 2.7 k, 4.7 k and 6.8 k ohm.
- Outputs switch between normally open (NO) and normally closed (NC) by jumper, rated 30 V DC, 500 mA.
- RS-485 bus up to 300 m on RVV 2 x 1.5 cable; address 0 to 15 on ARC9 and ARC2 series panels, 1 to 8 on the ARC3008.
- Remote firmware update through the client software.
- Runs on 12 V DC and draws about 1.2 W; 90 x 62 x 12.6 mm board.
What else you need
A compatible Dahua wired panel, a 12 V DC supply, normally taken from the panel’s auxiliary output, RS-485 bus cable and an enclosure. The matching expansion case is sold separately.
Installation
An alarm installer should fit it. Mount the board inside the panel cabinet or its case, set a unique address on the bus, wire the RS-485 bus and 12 V DC supply, then connect the zones with the chosen end-of-line resistors.
Software and licences
Firmware is updated remotely through the panel’s client software.
Before you buy
- Each module needs a unique address on the bus.
- It is a bare board: order the ARM808-RS expansion case or provide an enclosure.
- Operating range -10 to 55 °C.
