Abstract
Example devices, systems, and methods disclosed herein relate to a controller configured to control pressure maintenance in a fire protection system. A controller may be configured to control a fire pump to provide a first level of water pressure and to control operation of a jockey pump that is coupled in parallel with the fire pump to provide a second level of water pressure that is less than the first level. The controller is further configured to receive, from a pressure sensor coupled to the fire protection system, an output representative of the water pressure. The controller is configured to provide instructions to initiate the jockey pump based on a pressure value associated with the output being below a first value, and to provide instructions to initiate the fire pump based on the pressure value being below a second value that is less than the first value.
