ABSTRACT:
A periodic tester to determine the readiness of a fire pump system interfaces with a fire pump controller, an electric motor, and a sprinkler system. The fire pump controller has a power on/off sensor which interfaces with an electric motor which starts the fire pump to provide water to the sprinkler system. The power on/off system has a contactor coil as a component. The periodic tester targets two of the main components of fire system failure: the power on/off sensor and the contactor coil. The periodic tester may be retrofitted to existing systems and interface either directly or indirectly with the power on/off sensor to accommodate both systems that have a solenoid valve and those that do not. The periodic tester is designed to attempt to start the system only once during a set cycle. Any failure to start is displayed through audible and visual alarms.
