## Summary description

DAHUA ARD324-W2(868S) is a wireless door/window sensor using RF wireless connectivity in a white enclosure. It detects open/closed state for access control and alarm systems and pairs with compatible receivers on the 868 MHz band. Compact and easy to mount, it suits homes, offices and commercial premises for perimeter monitoring.

## Long description

DAHUA ARD324-W2(868S) is a compact wireless door/window sensor in a white enclosure that communicates over RF on the 868 MHz band. It detects open and closed states for perimeter monitoring and integrates with compatible alarm or access control receivers. The sensor is designed for easy surface mounting and provides basic environmental temperature reporting together with motion-impact and tilt detection.
Advantages
The sensor uses frequency hopping and two-way RF communication to maintain a stable link and supports communication encryption and jamming detection for improved signal reliability and security. It can display surrounding temperature and includes an overheating alarm. The device supports cloud updates and will automatically restore its previous state if a cloud update fails. Compact dimensions and a white finish make it unobtrusive on doors and frames.
Suitable for
Home perimeter monitoring (doors and windows)
Small offices and retail premises
Integration with alarm panels and RF receivers operating on 868 MHz
Locations requiring tamper/tilt and shock detection
When it may not be suitable
This sensor is intended for use with compatible 868 MHz receivers and alarm systems; it will not work with systems that use different RF bands or incompatible protocols. It is a wireless, battery-powered device and therefore may not be suitable for installations that require wired power or continuous high-bandwidth data transmission.
Key specifications
Wireless interface: RF (868 MHz)
Functions: open/closed contact detection, tilt detection, shock detection
Temperature: ambient temperature display and overheating alarm
Communication: frequency hopping, two-way communication, encryption, jamming detection
Form factor: compact surface-mount sensor, colour: white
How to use
Mount the sensor and magnet on the door and frame with the recommended spacing so the sensor detects open and closed states reliably. Pair the sensor with a compatible 868 MHz receiver or alarm panel following the receiver’s enrollment procedure. After pairing, verify RF link quality and enable cloud update if required. Place batteries and test tilt/shock and temperature alarm functions during commissioning.
What to consider before purchase
Compatibility with your alarm panel or RF receiver (must support 868 MHz and the same device protocol)
Installation location and mounting type (surface mount on door and frame)
Battery power and maintenance intervals
Requirement for encryption/jamming detection and cloud update support
Usage recommendations
Install the sensor within recommended range of the receiver to ensure stable RF communication, avoid placing it near large metal objects that can block signals, and perform regular tests of open/close, tilt/shock and temperature alarms after installation and during periodic maintenance.
