All about the product
X-SENSE FS121 Smoke Detector Kit
Ensure comprehensive protection for all your home or office spaces with the X-SENSE FS121 kit, which includes 12 XS01-M smart smoke detectors and an SBS50 base station. The system utilizes photoelectric smoke sensors and allows wireless communication between them, so when one alarm goes off, all connected devices are activated. An additional benefit is the integration with the X-Sense Home Security app, which offers useful notifications and device testing options, among other features.

Smart Protection for Your Entire Home
XS01-M sensors can operate as classic wireless detectors or work together with the SBS50 base station to provide advanced monitoring features. When smoke is detected, all connected detectors activate the alarm simultaneously, enhancing the safety of household members and allowing for quicker response to threats. The system supports up to 24 connected Link+ detectors and up to 50 devices connected to a single base station.

Continuous Access to Notifications and App Control
By connecting to the SBS50 base station and the X-Sense Home Security app, users can monitor device status from anywhere. The system sends real-time notifications about alarms, low battery levels, and more. Devices can also be tested and muted, and shared with other household members.

Reliable Wireless Connection
The kit operates at a frequency of 868 MHz, ensuring stable communication between devices even over long distances. Sensors in open spaces can reach up to 500 m transmission range, while the base station supports 2.4 GHz Wi-Fi connection up to 50 m away from the router. This allows the system to effectively protect multiple rooms and floors without additional wiring.

Loud Alarm and Mute Function
Each sensor emits an alarm with a volume of approximately 85 dB (from 3 meters away), effectively warning of fire danger. The system also features an alarm mute function for about 9 minutes, which is useful, for example, when the alarm is triggered accidentally, such as during cooking. Moreover, the base station includes a built-in speaker with voice announcements, reaching volumes up to 110 dB, and allows for alarm melody selection.

Long-lasting Operation and Easy Installation
XS01-M sensors use replaceable CR123A lithium batteries and last up to 10 years. Installation is straightforward and can be performed on the ceiling or wall using the included mounting hardware. Additionally, the compact sensor dimensions (78 × 78 × 48 mm) allow them to be discreetly placed in various rooms without compromising interior aesthetics.
