Overview
The Dahua ARM708-RS is an output expansion module for Dahua wired alarm control panels. This bare circuit board joins the panel’s RS-485 bus and adds 8 outputs that the panel can switch on alarm, on a schedule or by command. It suits a shop, office or warehouse that wants the alarm to drive extra sirens and strobes, trigger CCTV recorder inputs, release or lock doors, switch lighting or signal the state of each area to a building management system.
Is it right for you?
- It suits Dahua wired panels including the ARC2008C-V3 and ARC2016C-V3, which take up to 8 of these modules.
- The outputs are low-current contacts (30 V DC, 500 mA). A load above that, such as a large siren or mains equipment, must be switched through an interposing relay.
- It is an open board, so it must be mounted inside the panel cabinet or a separate enclosure.
- If you need more detector zones rather than outputs, the ARM808-RS is the matching input module.
Key features
- 8 alarm outputs, each switchable between normally open (NO) and normally closed (NC) by jumper.
- Output rating 30 V DC, 500 mA.
- Address set by DIP switch: 0 to 15 on ARC9 and ARC2 series panels, 1 to 8 on the ARC3008.
- RS-485 bus up to 300 m on RVV 2 x 1.5 cable.
- Remote firmware update through the client software.
- Runs on 12 V DC and draws about 1.8 W; compact 90 x 62 x 12.6 mm board.
What else you need
A compatible Dahua wired panel, a 12 V DC supply, RS-485 bus cable and an enclosure. The matching expansion case is available separately. Loads above 500 mA need an interposing relay.
Installation
An alarm installer should fit it. Mount the board inside the panel cabinet or its case, set the address on the DIP switch, wire the bus and 12 V DC supply, then connect each output to its siren, strobe, recorder input or relay.
Software and licences
Firmware is updated remotely through the panel’s client software. Output behaviour is set on the panel.
Before you buy
- Outputs are limited to 30 V DC, 500 mA; use an interposing relay for larger loads.
- It is a bare board: order the ARM708-RS expansion case or provide an enclosure.
- Operating range -10 to 55 °C.
