Rilevatore porta wireless Plus sensore DAHUA DHI-ARD324-W2(868) – rilevatore magnetico wireless per sistemi di allarme

Wireless Door Detector Plus is a smart sensor that monitors door or window open/close status and also measures ambient temperature. It supports overheating alerts and includes tilt and shock detection to report forced entry or impact events. The device uses secure two-way communication with frequency hopping and supports cloud updates with automatic rollback if an update fails.

Advantages

The detector provides combined contact, tilt and shock sensing in one compact unit while reporting temperature for environmental monitoring. Two-way communication with frequency hopping and encryption improves reliability and security. Cloud update support with automatic restore prevents device malfunction after a failed update. Jamming detection increases tamper resistance.

Key specifications

• Functions: open/close detection, ambient temperature measurement, overheating alarm, tilt detection, shock detection
• Communication: two-way communication with frequency hopping
• Security: communication encryption and jamming detection
• Firmware: supports cloud update with automatic restore on failure

How to use

Install the sensor on a door or window frame according to the manufacturer’s mounting instructions so the contact and magnet align. Pair the detector with the compatible alarm hub using the hub’s enrollment procedure. Configure temperature thresholds, tilt and shock sensitivity, and enable overheating alarm and jamming detection in the system settings. Place batteries and test device status and communication before leaving the installation.

Recommendations

For reliable operation, mount the detector on a sturdy surface, avoid placing it near strong sources of electromagnetic interference, and keep firmware updated via cloud updates. Regularly test alarms and replace batteries according to the manufacturer's guidance.
