Dual-Sensor Protection for Home and Travel

The BONAEVER 2-in-1 detector combines an electrochemical carbon monoxide sensor with an infrared photoelectric smoke sensor in a single unit. It is designed for homeowners, RV travellers and garage users who want simultaneous monitoring of both hazards without installing separate devices. The compact form factor allows flexible placement on walls or ceilings where space is limited.

Simple Mounting with Built-In Self-Test

Installation uses standard mounting hardware and requires no wiring, so the unit can be secured in minutes. A test button lets you verify sensor and alarm function at any time; pressing it during a nuisance alarm activates a 10 second silent mode indicated by a flashing LED. Low-battery warnings and the LCD status display reduce the chance of missed maintenance.

Check Power Source and Mounting Surface Before

The detector runs on replaceable batteries rather than mains power, so confirm you are prepared for periodic cell changes. Ensure the intended mounting surface can accept screws or adhesive pads and that local regulations do not mandate hard-wired interconnected alarms for your dwelling type. The LCD only illuminates when gas or smoke is detected, so it cannot serve as a constant room display.
