When smoke is detected, the device immediately activates a powerful audible alarm and sends a push notification to the smartphone via the Dahua DMSS app. Thanks to its combined smoke detection and siren function in a single housing, this device is particularly suitable for standalone alerting without a separate siren. It communicates via 868MHz and Wi-Fi for a stable connection with the AirShield Hub.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2-in-1: smoke detector with built-in siren — detection and alerting in a single device\u003c\/li\u003e\n\u003cli\u003e868MHz and Wi-Fi connectivity for a stable connection with the AirShield Hub\u003c\/li\u003e\n\u003cli\u003eImmediate push notification in the event of an alarm via the Dahua DMSS app\u003c\/li\u003e\n\u003cli\u003eCompatible with Dahua AirShield alarm systems\u003c\/li\u003e\n\u003cli\u003eFault detection and communication encryption\u003c\/li\u003e\n\u003cli\u003eWireless — easy installation without cabling\u003c\/li\u003e\n\u003cli\u003eCompact round design: Ø98 × 43 mm — discreet white design\u003c\/li\u003e\n\u003cli\u003eIndoor use\u003c\/li\u003e\n\u003cli\u003e3-year warranty\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStandalone fire detection and alerting in bedrooms and hallways\u003c\/li\u003e\n\u003cli\u003eFire protection in homes and small commercial premises\u003c\/li\u003e\n\u003cli\u003eExpansion of existing Dahua AirShield installations\u003c\/li\u003e\n\u003cli\u003eCombined fire and intrusion protection as part of a complete alarm system\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dahua","offers":[{"title":"Default Title","offer_id":57103650619716,"sku":"DHI-HY-SA21A-W2(868)","price":101.64,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0896\/8493\/4980\/files\/dahua-hy-sa21a-w2868-airshield-draadloze-rookmelder-met-sirene.jpg?v=1786669545","url":"https:\/\/ipcam-live.myshopify.com\/en\/products\/dhi-hy-sa21a-w2868","provider":"IPcam-shop.nl","version":"1.0","type":"link"}
