Fire Suppression Systems, Devices, and Methods
First Claim
1. A method of responding to a condition in an exhaust ventilation system including an exhaust hood, the method comprising:
- receiving a signal from a camera positioned to detect conditions of a cooking appliance;
detecting by a controller configured to receive the signals from the camera a fire condition responsively to the signals received from the camera; and
regulating by the controller a fire suppression mechanism responsively to the detecting.

Abstract
A method of responding to a condition in an exhaust ventilation system that has an exhaust hood includes receiving, at a control module, an exhaust air temperature signal representing a temperature of the exhaust air in a vicinity of the exhaust hood, the exhaust air temperature signal being generated by a temperature sensor. The method also includes receiving a radiant temperature signal representing a temperature of a surface of a cooking appliance that generates the exhaust air, the radiant temperature signal being generated by a radiant temperature sensor. Further, the method includes receiving a pressure signal representing the pressure in the hood and determining a state of the cooking appliance based on the received exhaust air temperature signal, the received radiant temperature signal, and the received pressure signal. Finally, the method responds to the determined appliance state by outputting a control signal from the control module.

10. A combined fire suppression and exhaust flow control system, comprising:
-
a controller receiving a first signal from at least a camera, the controller being configured to generate an exhaust flow rate command signal for controlling an exhaust flow rate responsively to the first signal from the camera; and the camera outputting the first signal, wherein the controller is further configured to generate a fire suppression command signal for controlling a fire suppression mechanism responsively to the first signal from the camera. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)
