Home safety alarm combining photoelectric smoke detection with electrochemical carbon monoxide sensing, promising long-lasting, hands-off protection. The meross Carbon Monoxide and Smoke Alarm gives peace of mind for families and landlords who want a reliable, low-maintenance warning system. Will the sealed 10-year battery and simple installation suit every home?
⚡ At a Glance
- • Detection Capability: Photoelectric smoke sensor and electrochemical CO sensor operate independently, with smoke alert preceding CO alarm and detection of both fast and slow-burning fires to reduce false alarms
- • Best for: Homeowners, renters and landlords seeking low-maintenance combined smoke and CO detection
- • Not ideal for: Properties that require hardwired, interlinked alarms or app-based smart-home notifications
Combines a photoelectric smoke detector with an electrochemical carbon monoxide sensor and a sealed 3V CR123A battery. Complies with EN 14604 and EN 50291 standards and includes a test/silence button plus LED status indicator.
Long-term, maintenance-free protection - thanks to a sealed 10-year battery
A built-in non-removable 3V CR123A battery is fitted inside the alarm, engineered to last up to 10 years without replacement. The design removes the need for periodic battery changes while preserving power for consistent sensor operation.
Long service life reduces the chance of unpowered alarms and removes routine battery checks. Households gain dependable protection for a decade with minimal upkeep.
Dual-hazard detection with clear sequencing - with photoelectric smoke and electrochemical CO sensors
Photoelectric smoke sensing is tuned to detect smoke from both fast and slow-burning fires, while an electrochemical module monitors carbon monoxide. Sensors operate independently, and the alarm prioritises the smoke alert before signalling CO if both hazards are present.
Accurate identification of smoke and CO reduces nuisance alerts and clarifies which hazard is present. Suitable for mixed-risk areas such as kitchen-adjacent corridors and sleeping spaces.
Quick DIY installation - with bracket activation and included fixings
Battery-powered unit mounts to a supplied bracket with screws and the internal smart chipset activates automatically when attached. The manufacturer states typical installation can be completed in about five minutes without electrical work.
Easy mounting means no electrician is required for most homes and flats. The automatic activation safeguards against missing a power connection during setup.
✨ The 4 Key Reasons for meross Carbon Monoxide and Smoke Alarm
- Independent sensor sequencing - Ensures smoke alarm sounds before CO, reducing occupant confusion
- Smart bracket activation - Automatically powers on when mounted, simplifying setup and readiness
- Test and silence button - Monthly testing and quick silencing of nuisance alarms without tools
- Low-profile white design - Blends into ceilings and walls while remaining visible for status indication
