- Voltage detector
The PowerOut Alert Power Failure Switch can be used with all Sensaphone models to monitor for the loss of power wherever it is plugged in. When the sensor detects a power failure, it will trigger the Sensaphone to go into alarm. The PowerOut Alert can be plugged into any 110 volt AC outlet. It requires no additional power for operation. The sensor is connected to the Sensaphone via accessory wire (not included).
