A fire detection and suppression system includes a fire suppression system configured to suppress a fire, an ambient temperature sensor, one or more temperature sensors, and a controller. The ambient temperature sensor measures an ambient temperature. The one or more temperature sensors are configured to measure a hazard temperature. The controller is configured to receive ambient temperature readings from the ambient temperature sensor and hazard temperature readings from the one or more temperature sensors over a learning time period. The controller is configured to determine one or more characteristic values based on the received ambient temperature readings and the hazard temperature readings over the learning time period. The controller is configured to use the one or more characteristic values to detect a fire condition. The controller is configured to activate the fire suppression system in response to detecting the fire condition.

Fire detection system with a learning mode

Systems and methods for monitoring clogging in a cooking hood () are disclosed. The systems and methods can include measuring temperature in the non-exhaust side of a filter () and measuring pressure in an exhaust side of the filter () using temperature and pressure sensors (). The systems and methods can further include comparing the measured temperatures and pressures to baseline temperature and pressure values to determine if clogging occurs using the controller (), which is communicatively coupled with the temperature and pressure sensors ().
