X-Sense Wi‑Fi Smoke Alarm XS01-M (EN 14604) — Works with SBS50 base station, X-Sense Home Security app
Product description
Key takeaways
If you’re trying to bring smoke detection into a connected home setup, the X-Sense XS01-M is the sort of accessory that fits the puzzle—provided you already have (or plan to get) the required SBS50 base station. It’s designed to send phone push notifications for alarms, low battery and faults via the X-Sense Home Security app, and it can also sound the system alarm with other devices at the same time.
It’s not a standalone smoke alarm in the usual sense: on its own, it requires the SBS50 base station to work with the Wi‑Fi app features. That dependency is the main thing to get right before you buy.
The essentials

The XS01-M is a Wi‑Fi smoke alarm detector accessory that is compliant with the EN 14604 standard. In practical terms, that means it’s built for everyday home fire-safety use, while the “smart” part focuses on how you’re alerted.
Where it stands out is the combination of notifications and shared awareness. When smoke is detected, you can get an instant push notification on your mobile, while the base station and each alarm in the system can sound simultaneously—handy if you’ve got multiple rooms covered.
What you’ll notice day to day


Day-to-day, you’re mainly dealing with alerts and testing.

- Push notifications: you should be able to monitor your home from anywhere through the X-Sense Home Security app, including real-time alarms and notifications for low battery or faults. You’ll also be told when the danger has passed.
- Test from the app: the app includes a Device Test function, so you can check the detector without needing to reach the physical test/silence button every time.
- Adjustable alarm output: the base station has a 100 dB adjustable sound, which can make the audible alert more reliable across a typical home layout.
One limitation to keep in mind: if you want the app/Wi‑Fi features, you need the SBS50 base station in the system and you’ll also need a 2.4 GHz Wi‑Fi network. The unit is stated as incompatible with 5 GHz.
Pairing and silence options
This is designed to be fairly quick to set up once the base station is in place. The base station connects to Wi‑Fi using a pair/silence button, and once paired, the app becomes your control point.

If an alarm goes off, you can silence the system either by using the silence button in the app or by a single push on the base station button. There’s also an emphasis on making regular checks straightforward—again, mostly through app-based testing.
A useful extra for households: the app includes a Device Sharing feature, letting you share the safety devices with family members so shared users can view history, receive push notifications, and silence devices.


Coverage and connectivity considerations
The product notes a long transmission distance of 1,640 ft (500 m). That’s a generous figure on paper, and it suggests it’s intended for flexible placement around a property.

However, real-world wireless performance depends on building materials and layout. So it’s worth thinking about whether thick walls, floors, or an awkward layout could reduce effective range—even if the headline transmission distance looks comfortably high.
Also, because this is an accessory for an existing ecosystem, make sure you’re matching it to the right kit logic (it requires the SBS50 base station).

In the box / what you should confirm before buying


The listing text points out that XS01-M requires the SBS50 base station to work. So before purchasing, it’s worth confirming you already have SBS50—or that you’re planning to buy it separately.
Also double-check your Wi‑Fi setup: if your router mainly uses 5 GHz and you don’t have 2.4 GHz enabled, you may be stuck. And if you’re building a full kit, ensure you’re buying the right alarm type for your existing X‑Sense setup.
Quick FAQ

Does the XS01-M work without the SBS50 base station? No—this model requires the SBS50 base station for the Wi‑Fi/app functionality.
Will I get notifications on my phone? Yes, the system is set up to send real-time push notifications via the X-Sense Home Security app.
Can I test it without reaching the alarm? The app includes a Device Test function, so you can run tests from your phone.
Is it compatible with both 2.4 GHz and 5 GHz Wi‑Fi? No, it’s stated as incompatible with 5 GHz and designed for 2.4 GHz.
Final verdict
Buy the X-Sense XS01-M if you’re adding smoke detection to an existing X-Sense connected setup and you already have the SBS50 base station (or you’re planning to). The app-driven notifications, app-based testing, and shared device access are genuinely practical for modern households.
It may not be the best choice if you want a simple standalone smoke alarm with no base station dependency, or if you only have 5 GHz Wi‑Fi available. In that situation, you’d likely be better off choosing a setup that doesn’t require the extra base station and matching Wi‑Fi conditions.
