Dahua ARD324 868MHz Wireless Door Window Detector Plus White for ARC3000H

The Door Detector Plus provides two detection functions in one wireless device: the standard magnetic reed switch that detects door or window opening (separation of the magnet from the sensor body), and an additional accelerometer or vibration element that detects the physical force applied to the door or window before it opens. This dual detection means the alarm can trigger from a hammering or kicking attack on a door that precedes the opening, rather than only after the door has been forced open.

The white housing matches standard white door frames, UPVC window frames, and white-painted surfaces, blending with the most common residential door and window frame finishes in UK properties.

The distinction from the DHI-ARD324-W2(868S) silver variant is purely cosmetic: the sensor specification and function are identical, with the silver variant offered for properties where silver door furniture and hardware are used and the white device would look inconsistent.

868MHz wireless connection to the ARC3000H hub requires no cable routing to the door or window position, allowing perimeter devices to be installed without drilling or chasing cable through door frames.

For Dahua ARC3000H alarm system installers specifying perimeter door and window protection in white hardware properties across London and the UK, the ARD324 white provides the wireless door detector with additional vibration protection.
