Meross Smart Smoke Alarm - MA151

3-in-1 Alarm Center: The Meross MA151 combines smoke, intrusion, and tamper detection in one device. Monitor your home remotely via the Meross app (supports multiple users) and receive real-time alerts for alarms, low battery, tampering, and hazard resolution. Stores 10 years of records. Can integrate with third-party platforms via the hub (automation not supported on Google). Reliable Home Security: The MSH450 hub and smoke detectors form a smart security system. When smoke is detected, the detector sounds an 85dB alarm (audible over 3 meters) and the hub emits a 110dB alert, triggering all linked alarms. Automation can cut power to high-load devices to prevent secondary fires. Paired with door and presence sensors, the smoke detector also acts as a siren to deter intruders during break-ins. Ultra-Low False Alarms: Equipped with dual photoelectric sensors and an advanced chipset, the Meross smoke detector accurately distinguishes smoke from steam. It meets the EU’s minimum smoke density standard and triggers in just 0.02s after repeated detection. A 0.8mm insect-proof mesh prevents interference. Certified by SGS, DBI, and EN14604 for maximum reliability. 10-Year Lifespan: This smoke alarm uses replaceable AA batteries with a 3-year lifespan and easy replacement. Built with V0 fire-retardant, anti-yellowing, UV-resistant materials, it offers up to 10 years of reliable operation.
