Dahua ARK32C-RW2 Wired LCD Keypad with Wireless Peripheral Support

Overview

The Dahua ARK32C-RW2 is a wired LCD keypad for Dahua hybrid alarm panels. It connects to the panel over RS-485, and it also contains a 433 MHz wireless receiver, a microphone and a speaker, so it doubles as a gateway for wireless devices and an intercom point. Fit it at the main entrance of an office, shop, clinic or home protected by a Dahua hybrid panel such as the ARC3808H: staff use it to arm and disarm, read system status and talk to the person monitoring through the app.

What else you need

A Dahua hybrid panel such as the ARC3808H, twisted-pair cable for the RS-485 bus and power run, and a 9 to 15 V DC supply, normally the panel’s auxiliary output. Intercom uses the Dahua DMSS app.

Installation

An alarm installer should fit it. Mount it on the wall at the entrance, run twisted-pair cable for RS-485 and power from the panel (within 200 m for intercom), wire any local inputs and output, then set it up on the panel and pair wireless devices through it.

Software and licences

Intercom works with the Dahua DMSS app. Firmware updates arrive through the cloud or the web interface. Menu languages include English, Italian, French, German, Portuguese, Dutch, Spanish, Turkish, Russian, Polish, Czech, Slovak, Danish, Hungarian, Croatian, Ukrainian, Swedish, Serbian, Greek and Bulgarian.

Before you buy

• Keep intercom devices within 200 m of the panel on the RS-485 bus.
• It draws up to 1 A, so check the panel’s auxiliary output budget.
• Indoor use only, IP30.
