Product description
This battery smoke alarm combines long lasting protection with straightforward installation, perfect for bedrooms, hallways and flats. It alerts quickly to smoke, offers a clear LED indicator and a simple silence function for nuisance alarms.
What matters most
The X-Sense SD11 prioritises reliable detection with fewer false alarms, according to the manufacturer. Its 85 dB sound level is designed to wake occupants, and the device runs on a sealed 10-year battery so you avoid repeated replacements. Ten-year coverage reduces maintenance and keeps protection constant.

What you’ll notice day to day
Installation is swift with the magnetic pad for flat surfaces, no drilling required, though screws are provided if you prefer a fixed fitting. The large test and silence button makes it easy to check or mute the siren when cooking triggers a false alert. A self-test routine runs every 60 seconds to flag faults or low power, helping maintain readiness.
Practical tips
The ABS casing is insect resistant and tolerates high temperatures, helping preserve sensor performance. Ten-year sealed power means the unit is maintenance light, but ten years is also the device life span to bear in mind. It is not compatible with SBS50 base stations and does not support interconnect or app features, so it functions as a standalone detector. Keep it away from dusty vents and direct airflow for best sensitivity.
