Ensure comprehensive protection for your entire home or office with the X-SENSE FS121 kit, which consists of 12 XS01-M smart smoke detectors and an SBS50 base station. The system uses photoelectric smoke sensors and enables wireless communication between them, so that triggering one alarm activates all connected devices. An additional advantage is its integration with the X-Sense Home Security app, which offers, among other things, useful notifications and a device testing option.
Smart protection for your entire homeThe XS01-M sensors can function as classic wireless alarms or work with the SBS50 base station to offer more advanced monitoring features. Upon detecting smoke, all connected alarms trigger an alert simultaneously, which increases the safety of household members and allows for a faster response to the threat. The system supports up to 24 connected Link+ alarms and up to 50 devices connected to a single base station.
Constant access to notifications and control via the appOnce connected to the SBS50 base station and the X-Sense Home Security app, users can monitor the status of devices from anywhere. The system sends real-time notifications about alarms, low battery levels, and more. It is also possible to test and silence devices, as well as share them with other household members.
Reliable wireless communicationThe kit operates on the 868 MHz frequency, ensuring stable communication between devices even over long distances. The sensors offer a transmission range of up to 500 m in open space, while the base station supports a 2.4 GHz Wi-Fi connection with a range of up to 50 m from the router. This allows the system to effectively secure multiple rooms and floors without the need for additional wiring.
Loud alarm and mute functionEach sensor emits an alarm with a volume of approximately 85 dB (from a distance of 3 meters), effectively warning of a fire hazard. The system is also equipped with an alarm mute function for approximately 9 minutes, which is useful, for example, when the alarm is triggered accidentally, such as while cooking. The base station, on the other hand, has a built-in speaker with voice messages at a volume of up to 110 dB and allows you to select an alarm melody.
Long-lasting performance and easy installationThe XS01-M sensors use replaceable CR123A lithium batteries and offer a service life of up to 10 years. Installation is simple and can be performed on the ceiling or wall using the included mounting hardware. Additionally, the sensors’ compact dimensions of 78 × 78 × 48 mm allow them to be discreetly placed in various rooms without affecting the interior’s aesthetics.
