VERY interesting! Checked the Sensor, and the failsafe was on "SET". Moved it to "HOLD" and same thing occured. Reviewed the manual, and I don't see any way to turn "Failsafe" off. In a sense, placing it in "hold" position is the same as turning it off.
It apparently is responding to an absense of transmitter signal. I didn't find any indication of a low voltage trigger, but this would be redundant with the voice/vibrator wasrning system.
