Claim 0:
1. A temperature monitoring apparatus to mitigate false trips of a valve that supplies water to a fire suppression system, the apparatus comprising:
a temperature sensor that detects a temperature of a dry piping system of the fire suppression system, the temperature sensor disposed in a low point of the piping system; an ambient temperature sensor disposed outside the piping system to measure an ambient temperature surrounding the piping system; a water detection sensor to detect a presence of water in the low point of the piping system; and a control circuit connected to the temperature sensor, the control circuit receives an indication of the temperature detected by the temperature sensor, the control circuit comprising one or more processors and a memory storing instructions that, when executed by the one or more processors, cause the control circuit to: determine whether water in the piping system is expected to freeze based on the indication of the temperature being less than a predetermined value and the ambient temperature being less than the temperature detected by the temperature sensor; predict whether a valve tripping event is expected to occur responsive to detection of the presence of water in the low point of the piping system and based on a determination that the water in the piping system is expected to freeze; and
in response to a prediction engine predicting that the valve tripping event is expected to occur, provide a prediction that the valve tripping event is expected to occur for remedial action.
