Abstract

A system for providing emergency alerts is provided. The system includes a plurality of sensors, a plurality of notification appliances, and processing circuitry. Each sensor monitors at least one parameter of a space and generates sensed data. Each notification appliance is operable to emit light in a plurality of colors. The processing circuitry detects, based on the sensed data, that at least one event among a plurality of events has occurred in the space, and determines a first evacuation path from the space that bypasses a location of the detected event. The processing circuitry further operates the plurality of notification appliances to emit light in a color assigned to the detected event among the plurality of colors and provide direction guidance for the first evacuation path. The direction guidance for the first evacuation path is provided by controlling one or more characteristics of the emitted light.

Claims (16)

1 . A system for providing evacuation path guidance, the system comprising:

sensors, each sensor: at a known location in a space, configured to monitor at least one parameter of the space, and configured to generate sensed data based on the monitored parameter;

notification appliances, each notification appliance: at a know known location in the space, and operable to emit light; and

processing circuitry, in communication with each sensor and each notification appliance and configured to:

detect, based on the sensed data, that at least one event among a plurality of event a gunshot event associated with a suspect is occurring at one or more event locations in the space;

determine, based on the detected event and the known location of the sensors, a first evacuation path in the space that bypasses at least one detected event location;

operate the notification appliances to provide direction guidance for the first evacuation path by controlling one or more characteristics of the emitted light, including disabling those notification appliances present in a movement trajectory of the suspect.

2 . A method for providing evacuation path guidance, the method comprising:

in processing circuitry, in communication with sensors and notification appliances, each sensor at a known location in a space, configured to monitor at least one parameter of the space, and configured to generate sensed data based on the monitored parameter, each notification appliance at a known location in the space, and operable to emit light:

detecting, based on the sensed data, that a gunshot event associated with a suspect is occurring at one or more event locations in the space;

determining, based on the detected event and the known location of the sensors, a first evacuation path in the space that bypasses at least one detected event location;

operating the notification appliances to provide direction guidance for the first evacuation path by controlling one or more characteristics of the emitted light, including disabling those notification appliances present in a movement trajectory of the suspect.

3 . A non-transitory computer-readable medium storing instructions that, when executed by processing circuitry the processing circuitry, in communication with sensors and notification appliances, each sensor at a known location in a space, configured to monitor at least one parameter of the space, and configured to generate sensed data based on the monitored parameter, each notification appliance at a known location in the space, and operable to emit light:

detecting, based on the sensed data, that a gunshot event associated with a suspect is occurring at one or more event locations in the space;

determining, based on the detected event and the known location of the sensors, a first evacuation path in the space that bypasses at least one detected event location;

operating the notification appliances to provide direction guidance for the first evacuation path by controlling one or more characteristics of the emitted light, including disabling those notification appliances present in a movement trajectory of the suspect.
