Remotely Monitor for 120VAC Power Failure

Monitor the power status of a 120VAC electrical outlet/system with the Sensaphone WSG30 Wireless Power Failure Sensor. This wireless sensor works with the Sensaphone WSG30 Wireless Sensor Gateway (sold separately), allowing you to remotely receive power outage alerts from anywhere you have internet access. The sensor plugs into a standard power outlet using the included 5VDC power supply in order to detect a power loss at that outlet. The two included AA alkaline batteries power the sensor continuously, allowing alarm transmission in the event that 120VAC power fails.

  • Monitors the power status of a 120VAC electrical outlet
  • Compatible with the WSG30 Wireless Sensor Gateway
  • Wireless range up to 300 feet (90m) indoors
  • Battery-powered with plug-in power supply to detect power failure

Installation Details

The sensor comes with screws and drywall anchors for mounting to a flat surface. It also includes two AA alkaline batteries to provide wireless power for up to two years.

The WSG30 series of wireless sensors have a standard wireless range of 300 feet from the Gateway. However, they also feature mesh networking technology, which allows each sensor to be used as either a wireless sensor/router or as a low-power battery operated sensor (also referred to as an end point). When used as a router, greater wireless ranges can be achieved, because each sensor/router in the network adds another 300 feet of range to the system.
