If you are in another room, the alarm should still work. On installation, our technicians perform a range test to ensure the system works from every room. If self-installed, INS recommends you test the system by following the instructions included in the Welcome Pack. This will help you to identify any potential limitations. If you have the LifeGuard SmartHome IP Dialler, you can also add the SmartHome Mate into any room to extend the range. The SmartHome Mate can be voice-activated and act as a talking call-point. We recommend regular testing as coverage can change over time.
