X-Sense XS0D-MR31 – Kit of 3 slim magnetic smoke alarms with SBS50 base
This kit pairs three slim XS0D-MR smoke alarms with an SBS50 base station for an interlinked, connected system. Each alarm fixes with screws or magnetic pads, so you can avoid drilling.
What the XS0D-MR31 brings day to day
Connected through the SBS50 base station, the alarms send instant notifications for fire detection, faults and low battery.
They join the X-Sense Link+ and Link+ Pro series, creating an interconnected network that keeps working even if the base goes offline.
Magnetic pads allow quick removal and replacement without leaving holes in the ceiling.
Home Assistant compatibility lets you trigger your own automations, such as flashing lights, when smoke is detected.
Each alarm has an 85 dB buzzer, while the base sounds at 100 dB and sends notifications at the same time.
The replaceable CR123A battery lasts up to 5 years with weekly self-checks, within a 10-year service life.
