Abstract: A fire suppression system includes a container of fire suppressant, a nozzle positioned to direct the fire suppressant from the container towards a hazard, and an actuator configured to cause the fire suppressant to pass from the container to the nozzle. The system also includes a user interface, a controller coupled to the actuator and the user interface, a first sensor coupled to the controller and configured to provide first data indicating the presence of a fire, and a second sensor coupled to the controller and configured to provide second data indicating an internal characteristic of the controller. The controller is configured to identify an event base on the first or second data, control the actuator if the event is a fire, control the user interface to provide a notification if the event is a fault, and record second data to a storage device.

Abstract: A fire suppression system includes an interface control module, and an interface module. The interface control module can activate a fire suppressant discharge system in response to receiving a fire detection signal. The interface module is connected with the interface control module and is connected with at least one of a first optical sensor and an interface expansion module. The interface expansion module is configured to connect with a second optical sensor. The first optical sensor and the second optical sensor are configured to detect a fire condition at an area of interest and provide the first detection signal to the interface control module in response to detecting the fire. The interface module includes light emitting devices corresponding to the first optical sensor and the interface expansion module, the light emitting devices configured to display different colors indicating a status of the first optical sensor and the interface expansion module.
