- 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 responds with ultra-fast triggering even 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.
- Easy Pairing & Mute: Connect the hub to Wi-Fi using the pairing/mute button. You can quickly silence the system via the app or by pressing the button on the hub.
- Ready-to-Use Pack: Includes 1 MSH450 hub, 1/3 MA151 smoke detectors (with screws and 3M adhesive for flexible installation), 1 power adapter, 1 power cable, and 1 Ethernet cable. Just download the Meross app and connect via 2.4GHz Wi-Fi (not compatible with 5GHz) to start protecting your home.
