Introducing MSC-1,
The Matter-Thread Smoke & CO Alarm

Frequently Asked Questions

• What is MSC-1?

  MSC-1 is a combination smoke and carbon monoxide alarm with Matter over Thread support. It detects both smoke from fires and carbon monoxide gas using dedicated sensors, and can integrate with Matter compatible smart home ecosystems.

• What type of smoke sensor does MSC-1 use?

  MSC-1 uses an advanced photoelectric smoke sensor, a technology widely adopted in modern residential smoke alarms.

• Does MSC-1 use an ionization smoke sensor?

  No. MSC-1 does not use an ionization sensor.

• Why did you choose a photoelectric smoke sensor?

  Photoelectric sensors are commonly used in modern residential smoke alarms and are well suited for household fire detection scenarios. They also avoid the regulatory and end-of-life considerations associated with ionization based sensors.

• Can a photoelectric sensor detect fast flaming fires?

  Yes. Modern photoelectric smoke alarms are designed to respond to both smoldering and fast flaming fire scenarios. Overall detection performance depends on the complete system design, including airflow structure and alarm logic.

• Does MSC-1 emit radiation?

  No. MSC-1 does not contain radioactive materials and does not emit radiation.

• How does MSC-1 detect carbon monoxide?

  MSC-1 uses a dedicated electrochemical carbon monoxide sensor that continuously monitors CO concentration and triggers alarms according to safety thresholds defined by applicable standards.

• What are common sources of carbon monoxide that MSC-1 can detect?

  Carbon monoxide is produced by incomplete combustion. Common sources include gas boilers, fireplaces, gas stoves, charcoal grills, portable heaters, and vehicle exhaust in enclosed or poorly ventilated spaces.

• Which safety standards does MSC-1 follow?

  MSC-1 is designed and certified according to European safety standards:
  EN14604 for smoke alarms
  EN50291 for carbon monoxide alarms
  These standards define requirements such as detection behavior, alarm timing, and sound patterns.

• Can MSC-1 be used outside Europe?

  Yes. MSC-1 can be used outside Europe. However, whether it can pass local fire safety inspections depends on local regulations and enforcement requirements in each region.

• Why do fire safety standards differ between regions?

  Fire safety standards are not unified globally. Different regions use different technical frameworks and regulatory systems. No standard is inherently more stringent than another. Differences usually relate to structural or behavioral requirements such as alarm patterns, test methods, or installation rules.

• Which smart home ecosystems support MSC-1?

  MSC-1 is compatible with smart home ecosystems that support Matter.

  In practice, MSC-1 has been tested and verified to work with major platforms including Apple Home, Google Home, Samsung SmartThings, Home Assistant, and Homey. Platform features and user interfaces may vary between ecosystems.

• Do I need a hub to use MSC-1?

  For smart features and remote notifications, a compatible Thread Border Router is required. MSC-1 will still function fully as a standalone smoke and carbon monoxide alarm without a smart home connection.

• Can I silence the alarm remotely?

  No. Remote silencing is currently not supported.

  For safety reasons, most smart home ecosystems do not allow smoke or carbon monoxide alarms to be silenced remotely. Alarm silencing must be performed locally on the device.

• How does self test work? Can it be triggered remotely?

  MSC-1 includes a built-in self test function that checks core electronics and the alarm sound.

  Whether self test can be triggered remotely depends on the smart home platform and its user interface. Some platforms, such as Home Assistant, expose a self test control that allows it to be triggered through the app. Other ecosystems may not display a dedicated self test UI even though the device supports the function.

• Does MSC-1 support interlinking between alarms?

  Interlinking between alarms is not currently supported.

  Support for alarm interlinking depends on platform level implementations within smart home ecosystems.

• What is the expected service life of MSC-1?

  MSC-1 is designed with an expected service life of 10 years under normal residential use.

• What battery does MSC-1 use and how often should it be replaced?

  MSC-1 uses a CR123 battery. Battery life depends on operating conditions and usage, but under typical conditions the battery is expected to be replaced approximately every three years.

• Where should MSC-1 be installed?

  MSC-1 should be installed according to local fire safety guidelines. Typical locations include bedrooms, hallways, and areas near combustion appliances, while avoiding kitchens or bathrooms where steam or cooking fumes may cause nuisance alarms.

• Does MSC-1 work without a smart home system?

  Yes. MSC-1 functions fully as a standalone smoke and carbon monoxide alarm even without a smart home setup. Smart home features enhance visibility and notifications but are not required for core safety operation.

• Do the devices have proper U.S. certifications or are they UL listed?

  The current MSC-1 smoke alarm is certified under EN 14604 and EN 50291 standards for the European market. We are also actively developing a new model that meets UL 217 and UL 2034 standards for the U.S. market and will share updates once the certification process progresses.
