Methods and systems for overcurrent protection in a fire pump control system
Methods and systems for a fire pump control system are provided. An example fire pump control system includes a pump system having a given full load current, wherein the pump system comprises (i) a fire pump, (ii) a first disconnect switch and (iii) a first circuit breaker. The first disconnect switch and the first circuit breaker are located upstream of the fire pump. The system further includes a controller configured to control operation of the fire pump, and the controller comprises a second disconnect switch and a second circuit breaker. The controller is located upstream of the first disconnect switch and the first circuit breaker, and is configured to avoid (i) opening within two minutes at 600 percent of the full load current, (ii) opening with a restart transient of 24 times the full load current, and (iii) opening within 10 minutes at 300 percent of the full load current.

Fire suppression system and emergency annunciation system
A fire suppression and annunciation system using a flexible conduit and a wire rope is provided. The wire rope may be connected to a knob assembly at a universal pull station and to a release mechanism of the fire suppression system. An operator may pull a handle of the knob assembly at the universal pull station, thereby activating the release mechanism to release fire suppression agent. A flexible conduit may house the wire rope along at least a part of the connection from the universal pull station to the release mechanism. A material on the liner of the flexible conduit and/or on the wire rope may be used to reduce the coefficient of friction of wire rope in the flexible conduit. The fire suppression system may further include a pulley block system connected to the universal pull station. The pulley block system may comprise bearings, and may lower the force necessary to activate the release mechanism.

STOVE TOP FIRE EXTINGUISHING DEVICE
An apparatus is disclosed for extinguishing a stovetop fire over a stovetop having a first burner, the apparatus including a container detachably mountable to a microwave positioned above the stove top. A supply of fire suppressant material is retained within the container. A heat responsive actuator is disposed on the container. When the container is mounted to the microwave over the first burner, and the fire actuates the heat responsive actuator, at least a portion of the supply of fire suppressant material falls from the container toward the first burner.

Fire fighting systems and methods
The method of maintaining a first flow rate through a first valve in a fluid delivery system, the fluid delivery system including a and a plurality of fluid valves in fluid communication with the pump, and a controller controlling the pressure generated by the pump and the position of the plurality of valves. The method includes providing the first flow rate of a fluid pressurized by the pump through the first valve, receiving a request for a second flow rate of the fluid through a second valve, determining a predicted effect on the first flow rate based on the request, adjusting at least one of the position of the first valve and the pressure generated by the pump to maintain the first flow rate based on the predicted effect, and adjusting the position of the second valve to provide the second flow rate of the fluid through the second valve.
