Frequently Asked Questions (FAQ)

Is deze detector geschikt voor gebruik binnenshuis met een AirShield-systeem?
Ja, deze draadloze gas- en CO-detector is ontworpen voor binnenshuis en werkt met AirShield-alarmsystemen. Dat maakt hem geschikt voor woningen waar gas- en koolmonoxidebewaking gewenst is.
Hoe word ik gewaarschuwd als er een lek of gevaarlijke gasconcentratie wordt gedetecteerd?
Bij detectie stuurt het apparaat direct een alarm naar de AirShield Hub en een pushmelding via de Dahua DMSS-app. Zo krijgt u snel melding, ook als u niet naast de hub staat.
Welke verbinding gebruikt deze detector?
De detector communiceert via 868MHz en Wi‑Fi. Dat helpt voor een stabiele verbinding en maakt draadloze plaatsing eenvoudiger binnen een AirShield-opstelling.
Welke app heb ik nodig om meldingen te ontvangen?
De detector werkt met de Dahua DMSS-app. Daarmee ontvangt u pushmeldingen op uw smartphone, zodat u waarschuwingen onderweg of thuis eenvoudig kunt opvolgen.
Is dit alleen een gasdetector, of meet hij ook koolmonoxide?
Hij detecteert zowel gas als koolmonoxide. Dat is handig als u één apparaat wilt voor meerdere risicosoorten in huis in plaats van aparte detectoren.
