Abstract
An automatic failure detecting device for detecting failure in a pressure sensor for a fire pump controller, the failure detecting device comprising a three-way valve connecting the pressure sensor to a water line, wherein when the three-way valve is activated, the pressure sensor is exposed to the atmosphere to measure the atmospheric pressure, and wherein the failure detection device signals a fault if said measured atmospheric pressure differs from a standard expected value.

An automatic failure detecting device for detecting failure in a pressure sensor for a fire pump controller, the failure detecting device comprising a three-way valve connecting the pressure sensor to a water line, wherein when said three-way valve is activated, the pressure sensor is exposed to the atmosphere to measure the atmospheric pressure, and wherein the failure detection device signals a fault if said measured atmospheric pressure differs from a standard expected value.
A method for automatically detecting failure in a pressure sensor for a fire pump controller, the method comprising the steps of:
- exposing the pressure sensor to the atmosphere by activating a three-way valve connecting the pressure sensor to a water line;
- measuring an atmospheric pressure;
- comparing said measured atmospheric pressure to a standard expected value;
- and
- signaling a fault if said measured atmospheric pressure and said standard reading differ.
