Test scoreShow Context
- Smoke alarm
- Mains only
- Optical smoke alarm
The Kidde 2SFW mains-powered optical smoke alarm can be fitted as a standalone alarm or used as part of a wireless network of alarms. There are two buttons, one to test it – we recommend you do this weekly – and a hush button to silence it after sounding. A 9V battery will provide back-up power if there’s a power cut. And it comes with a warranty from the manufacturer covering its six-year lifetime. But what’s it like at detecting smoke and sounding the alarm? We tested it to find out. Read on to learn about how this Kidde mains-powered smoke alarm fared in our tough lab tests.
