Alecto SDX10 Smoke and Carbon Monoxide Detector Set

In a family home, early warning is everything. The Alecto SDX10 set pairs a photoelectric smoke detector with an electrochemical carbon monoxide detector, covering two critical safety threats in one package. The smoke detector mounts on ceiling or wall and runs for up to 10 years on its sealed lithium battery, while the CO detector uses replaceable AA batteries for up to 3 years of protection. Both units sound an 85 dB alarm at 3 meters and include test, low-battery, and end-of-life indicators.

Why choose it

Dual protection in one purchase means you don't have to compromise. The sealed smoke detector battery eliminates annual battery changes for a decade, while the CO detector's replaceable cells keep ongoing costs low. Both units are certified to current European standards, giving you confidence in their reliability. The loud 85 dB alarm ensures you'll hear it from another room, and the end-of-life warning tells you when it's time to replace the unit.

Ideal use cases

• Protecting bedrooms and hallways in residential homes
• Supplementing existing fire safety systems in rental properties
• Providing carbon monoxide detection near fuel-burning appliances
• Meeting landlord safety requirements for smoke and CO alarms

Good to know

Both detectors feature a test button for regular function checks and a low-battery indicator to alert you when power is running low. The smoke detector's sealed battery is designed to last the entire 10-year lifespan of the unit, while the CO detector's AA batteries are easy to replace. The set includes mounting hardware for quick installation on walls or ceilings.
