X-Sense makes safety simple with a system that actually works for modern homes. The SC07-MR51 bundle is a battery-operated, interconnected 5-pack that connects to your phone. This is the crucial upgrade over basic standalone alarms. When one detector senses smoke or carbon monoxide, all five sound together, buying you critical extra seconds to get out.

The system connects via a single plug-in base station to your home’s 2.4 GHz Wi-Fi network. You get instant app alerts if an alarm triggers while you’re away, so you can call a neighbor or emergency services. The detectors themselves are straightforward—easy to mount with a twist-lock base and powered by long-lasting batteries. You’re covered in key areas without dealing with hardwired installation.

Just know the Wi-Fi requirement is specific. The base station needs a 2.4 GHz signal to function; it won’t connect to 5 GHz networks. For renters or anyone avoiding electrical work, this pack delivers professional-grade, interconnected protection with smart features, provided your router can handle it.
