1. A fire suppression system comprising:
a controller configured to:
receive sensor data regarding a fire condition from a sensor indicating a location of an area in which the fire condition is detected;
determine a fire suppression response profile based on the sensor data and a type of appliance at the location that the fire condition is detected; and
transmit a control signal to each of a plurality of electronically controllable variable flow rate nozzles, the control signal being pulse width modulated based on the fire suppression response profile, to selectively control a flow rate of each of the plurality of electronically controllable variable flow rate nozzles over time to provide a fire suppressant agent to a plurality of zones according to the fire suppression response profile, wherein the flow rate of each of the plurality of electronically controllable variable flow rate nozzles is independently adjustable by transitioning each of the electronically controllable variable flow rate nozzles between an activated state and a deactivated state over a time period.
