About This Item
FM Approvals 1321/1323 encompasses the design and performance requirements for controllers for electric motor driven and diesel engine driven fire pumps used in fire pump service that are designed and installed in accordance with the applicable documents listed in Section 1.8 and the FM Global Property Loss Prevention Data Sheets. The intended operation of a fire pump controller is to initiate and sustain the operation of the fire pump driver in the event of a fire. In addition, controllers are tested under specified overload and fault conditions. To this extent the fire pump controller is unique when compared to other industrial motor controllers, and system reliability is improved by provisions for self testing and annunciation of conditions that could result in fire protection impairment.
