Gem Sensor 3100 Recall Notice On April 24, 2012 the Consumer Product Safety Commission (CPSC) issued a press release, CPSC #12‐156 , for the voluntary recall of Gems 3100 Pressure Detectors/Transducers because the transducer can fail to accurately detect water pressure in a fire suppression sprinkler system. This could cause the sprinkler system to fail to activate and pump water to the sprinklers in the event of a fire. The failure associated with the Transducer is not a sudden loss of function but rather a slow degradation of performance over many hours of continuous use with constant water pressure. The use of the transducer in non‐water and/or fluctuating pressure applications has not shown the same potential problem. The sensors are basically failing in a "high" pressure rating (e.g. will read 100 PSI higher than actual pressure). So it is easy to spot, but does require good on-going maintenance. One should install a calibrated gauge and compare the pressur...
