Smart smoke detector MEROSS MA151HMATRI-EU

The MEROSS MA151HMATRI-EU smoke detector uses advanced dual optical detection technology to provide fast and accurate detection of danger before a fire breaks out. With a loud alarm ≥85 dB, audible from a distance of 3 meters, and full 360° coverage, the device effectively increases the safety of household members. The compact design with dimensions of 125 × 125 × 33 mm, mounted on the ceiling and powered by two AA batteries, ensures convenient installation and long operation of up to 3 years.

Accurate smoke detection and fewer false alarms

The use of dual optical detection technology allows the detection of both white and black smoke, which significantly increases the efficiency of the sensor. Multi-standard optics ensure sensitivity and accuracy of measurements, while reducing the risk of unnecessary alarms. In addition, the device performs automatic self-tests, which can also be triggered via the app, ensuring that the system is working properly at all times.

Integrated alarm system for the whole home

The sensor works with a dedicated Meross hub, allowing you to create a connected alarm system. If one device detects smoke, all paired sensors trigger an alarm, increasing the effectiveness of alerts throughout the home. Even if the hub has no internet or power, local communication continues to work, ensuring uninterrupted protection. The hub itself has an audible alarm with a volume of 110 dB and an extremely fast response time of 2 ms.

Smart scenarios and full control via the app

With the Meross app, you can create automations that improve safety and comfort. For example, smoke detection can automatically turn off other devices in your home. The app also lets you view event history up to 10 years ago and sends notifications about alarms, low battery, device issues, or when your device is offline. Important alerts can bypass your smartphone's silent mode, ensuring you don't miss important information.

User comfort and functions adapted to everyday life

Do Not Disturb mode lets you turn off indicator lights and low battery notifications at night, promoting a restful night’s sleep. The alarm silence function lasts for about 10 minutes, and the low battery warning can be temporarily disabled for about 10 hours. In addition, the device is tested directly from your smartphone, so you don’t have to reach for the ceiling-mounted sensor.

Same summary

The MEROSS MA151HMATRI-EU smart smoke detector is designed primarily for users who want an additional level of security in an apartment or smaller home, where smoke recognition and the ability to immediately notify play a key role. It is suitable for spaces where there are no requirements for installation in the installation, as well as for holiday properties or spaces where it is necessary to quickly and non-invasively add basic protection against a fire outbreak. Smart functions and connectivity with the app are especially useful for those who want control even when they are not at home, but a classic alarm remains crucial for basic security. If there are other sources of risk in the room, such as gas or carbon monoxide, it may be worthwhile to consider additional types of detectors for complete protection.

Answers to frequently asked questions

Does the detector also detect gas or carbon monoxide?

This model only detects smoke. If you also want to monitor for the presence of gas or carbon monoxide, we recommend a separate detector dedicated to this type of hazard.

How often should the detector be checked for operation?

It is recommended to check the operation once a month, especially if it is installed in a room where there is no daily supervision, such as weekend rooms or guest rooms.

Where is it best to install a smoke detector?

It is advisable to install the detector on the ceiling in the central part of the room where the probability of smoke is highest (e.g. a hallway between bedrooms or in the living room). Avoid mounting near ventilation openings or the kitchen, where false alarms can occur.

Does the detector work without a smartphone connection?

Yes, the basic functionality of the alarm is independent of the connection to the phone; this means that the detector will trigger an audible alarm even if there is no connection to the app.

How long does the battery last and how do I know when it is empty?

Battery life depends on usage, but as a rule, the device itself notifies you when the battery is almost empty with a light or sound signal.
