## Summary description

Combined smoke and carbon monoxide alarm Eura CSD-39A2 provides detection of both smoke (fire) and CO (carbon monoxide) in one unit. The device is designed for residential and small commercial use to warn occupants of fire and toxic gas hazards. Suitable for installation in hallways, living rooms and bedrooms to provide early audible alerts and enhance indoor safety.

## Long description

The Eura CSD-39A2 combined smoke and carbon monoxide alarm integrates two detection functions into a single unit to provide early warning of fire and dangerous CO levels in residential and small commercial spaces. Designed for installation on ceilings or walls, the device monitors air for combustion products and carbon monoxide and issues an audible alarm when thresholds are exceeded. It operates on mains power with battery backup, ensuring continued protection during power interruptions.
Advantages
The dual-sensor design reduces the need for separate detectors by combining photoelectric smoke detection and an electrochemical CO sensor in one housing. Mains operation with battery backup ensures continuous monitoring even during power outages. The alarm features a clear, loud audible signal for prompt notification and a test/reset function for functional checks and silencing nuisance alerts. Compact form and straightforward mounting make installation and maintenance practical for homes and small businesses.
Suitable for
Private homes and apartments — hallways, living rooms, bedrooms
Small offices and commercial premises
Holiday rentals and guest accommodation
Areas where combined smoke and CO monitoring reduces the number of devices required

How to use

Replace backup batteries according to the manufacturer’s guidance and replace the unit at the end of its service life to maintain reliable protection.
Usage recommendations
Place the alarm in circulation areas such as hallways and living spaces for optimal detection. Avoid placing the unit directly above cooking appliances or bathrooms to reduce false alarms, and keep the sensors free from dust and paint.
