Fire Pump Sensor Recall

Gem Sensor 3100 Recall Notice

Gem Sensor - Old 3100 model
Gem Sensor - Model 3300 (new)
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 pressures.

The transducer has "Gems Sensors & Controls," as well as the 18- digit part number, printed on a label affixed to the center of the transducer. Part numbers beginning with "3100" are included in this recall.

Gems sold the recalled 3100 Pressure Transducers directly to end-users and through distributors from January 2006 through February 2012.

The 3100 has been replaced with the new 3300 series model.  Replacement transducers are avaliable at no cost from Gem.

The newer 3300 model has a green sticker as shown in the figure to the right.  The older 3100 model has a white sticker.
