{"product_id":"dhi-magnetic-contact-ard323","title":"DHI Magnetic Contact ARD323","description":"\u003cp\u003eARD323-W2(868) is a wireless door and window detector from Dahua, intended to complement alarm systems built around Dahua's wireless hubs. The detector uses a reed switch sensor that detects when the door or window is opened, and is adapted for mounting on non-metallic doors and windows.\u003c\/p\u003e\r\n\u003cp\u003eThanks to two-way communication and frequency hopping, the detector communicates stably and interference-free with the hub, with a range of up to 1,200 meters in open areas. The unit is powered by a CR123A battery with a lifespan of up to 4 years (2 years with external input of type NC or pulse), and automatically warns of low battery level. Built-in temperature monitoring, signal strength indication, and tamper protection provide extra security and an overview of the system's status directly in the app.\u003c\/p\u003e\r\n\u003cp\u003eThe detector supports cloud-based remote updates with automatic recovery if an update fails, as well as a test mode for easy operational control during installation. With certification according to EN 50131 Grade 2, the ARD323-W2(868) is suitable for both private homes and professional installations.\u003c\/p\u003e\r\n\u003ch3\u003eKey features\u003c\/h3\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eReed switch sensor for door\/window detection\u003c\/li\u003e\r\n\u003cli\u003eSignal strength indication\u003c\/li\u003e\r\n\u003cli\u003eLow battery warning\u003c\/li\u003e\r\n\u003cli\u003eTemperature monitoring (–15 °C to +65 °C)\u003c\/li\u003e\r\n\u003cli\u003eFrequency hopping and two-way communication for stable wireless connection\u003c\/li\u003e\r\n\u003cli\u003eCloud update with automatic recovery on failed update\u003c\/li\u003e\r\n\u003cli\u003eTest mode for easy installation control\u003c\/li\u003e\r\n\u003cli\u003eTamper protection\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\r\n\r\n\u003ctable\u003e\r\n\u003cthead\u003e\r\n\u003ctr\u003e\r\n\u003cth\u003eFeature\u003c\/th\u003e\r\n\u003cth\u003eValue\u003c\/th\u003e\r\n\u003c\/tr\u003e\r\n\u003c\/thead\u003e\r\n\u003ctbody\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eIndicator light\u003c\/td\u003e\r\n\u003ctd\u003e1 x green alarm indicator\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eButton\u003c\/td\u003e\r\n\u003ctd\u003e1 x power switch\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eRemote update\u003c\/td\u003e\r\n\u003ctd\u003eCloud update\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eLow battery warning\u003c\/td\u003e\r\n\u003ctd\u003eYes\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eTamper protection\u003c\/td\u003e\r\n\u003ctd\u003eYes\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eMeasurement range (temperature)\u003c\/td\u003e\r\n\u003ctd\u003e–15 °C to +65 °C (indoor)\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eSensor\u003c\/td\u003e\r\n\u003ctd\u003eReed switch\u003c\/td\u003e\r\n\u003c\/tr\u003e\r\n\u003ctr\u003e\r\n\u003ctd\u003eTrigger distance\u003c\/td\u003e\r\n\u003ctd\u003e\u0026lt;
