Smoke alarm SD11 with 10-year battery
Product description
Your home needs clear warning if smoke appears, and the X-Sense SD11 smoke alarm is designed for that everyday job. It is a battery operated unit with a long service life, plus simple installation and an easy test and silence button, so you can keep protection in place without fuss. If you want a reliable smoke detector for a typical domestic setup, this 10 year battery fire alarm is a practical choice.
The essentials

The X-Sense Smoke Alarm SD11 is a home smoke detector that focuses on fast detection while aiming to keep false alarms to a minimum, according to the manufacturer. It uses an 85 dB alarm so the sound is loud enough to wake you, which can make a difference when every second matters. As a TÜV Rheinland-certified alarm that conforms to EN 14604, it is built to meet recognised safety expectations for domestic smoke alarms. 🏠


A key convenience is the 10 year battery life. You are not expected to replace the battery during that period, and the alarm is described as having low power consumption for steady, long term use. There is also a self test feature that checks for faults or a low battery condition every 60 seconds, helping you stay confident it is functioning. 🔋

Installation is straightforward. On flat surfaces, you can use the included magnetic pad for a quick attachment without drilling, which is handy if you do not want holes. If you prefer a more traditional approach, the instructions also allow screws for fixing. The alarm includes an LED indicator, along with a large button that makes test and silence actions quick and simple.

Key features

This smoke alarm is built around consistent day to day reliability. A self test routine checks for faults or low battery every 60 seconds, so the unit does not rely only on you remembering to test occasionally. If you want a detector you can trust to keep checking itself, that continuous approach is a helpful safety habit.


For quick interaction, the test and silence function uses a single large button on the device. That means you can test the alarm or silence it without searching for controls, and it keeps routine checks manageable. The manufacturer also describes the alarm as having an insect-proof design, made from durable ABS material, to help prevent bugs from obstructing performance, particularly where insects may be an issue. 🐜

There is an important compatibility limitation to be aware of. The SD11 smoke alarm is not compatible with an SBS50 base station, and it does not support interconnect functions or any app based features. So if you are building a system that relies on interconnection, you will need to choose accordingly before purchasing.
On the practical side, the magnetic mount option can reduce installation time and keep the area neat when you want no holes. Alternatively, screw mounting remains available if your surface or preferred method calls for it. The LED indicator also supports day to day awareness of the unit status, while the 85 dB alarm aims to be heard clearly when action is needed.

Who it’s for
It’s a good fit if you want a straightforward battery operated smoke detector for a home, with long term battery life and simple controls. You’ll like it if you value easy mounting, either with the magnetic pad for flat surfaces or screws when you want a more permanent fix. It may not suit you if your plan depends on an SBS50 base station, interconnect wiring, or app based features, because the SD11 does not support those functions. If you want a single alarm that conforms to EN 14604 and keeps running with frequent self checks, this SD11 design is worth considering for everyday household protection.
