Fire Pump Sensor Recall

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 pressures.

Fire Pump Sizing App

We are pleased to offer a  NFPA 20 fire pump sizing app  to our clients.  This app allows you to quickly look up the minimum required suction, discharge, test header, number of hose valves, and relief valve size.  These are the recommended sizes and we recommend a quick phone call to discuss your project specific conditions.
