Smart fire detection systems and methods

A method for operating a fire detection and suppression system, comprising:

• providing a fire suppression system configured to suppress a fire in an area;
• providing a temperature sensor configured to measure a zone temperature for each of a plurality of zones in the area;
• detecting, based on the zone temperatures, a hazard condition in at least one of the plurality of zones;
• and
• activating the fire suppression system in response to detecting the hazard condition.

A controller for a fire suppression system in a hazard area, the controller comprising processing circuitry configured to:

• receive a plurality of zone temperatures from a temperature sensor positioned in the hazard area, wherein each of the plurality of zone temperatures correspond to a zone of a plurality of zones in the hazard area;
• detect a hazard condition in a first zone of the hazard area based on a zone temperature of the plurality of zone temperatures corresponding to the first zone;
• and
• activate the fire suppression system in response to detecting the hazard condition in the first zone, wherein the fire suppression system comprises:
• a fire suppression tank configured to contain a volume of fire suppressant;
• a plurality of nozzles having outlets at least selectively fluidly coupled to the fire suppression tank and configured to release sprays of the fire suppressant therefrom, wherein each of the plurality of nozzles is associated with at least one of the plurality of zones;
• and
• an activator configured to selectively activate the fire suppression system individually in each of the plurality of zones, such that in response to detecting the hazard condition in the first zone the fire suppression system selectively releases fire suppressant in the first zone and not in a second zone of the plurality of zones.
