SYSTEMS AND METHODS FOR TEMPORARY PAUSING OF UTILITY ALARM
A utility sensor module includes one or more sensors and an electronic processor. The electronic processor is configured to receive a pause mode command and initiate a pause mode timer at a first predefined timer value in response to receiving the pause mode command. The electronic processor is further configured to change an operating mode of the utility sensor module to a pause mode, wherein operation in the pause mode causes the sensor module to not generate an alarm when a parameter sensed by the sensors exceeds a predetermined threshold. The electronic processor is also configured to transmit a signal to a utility system indicating that the operating mode has been changed to the pause mode and determine whether the pause mode timer has expired. In response to determining that the pause mode timer has expired, the electronic processor changes the operating mode to a normal operation.
