    Abstract: A signaling device control system includes a user interface and an association mapper. The user interface presents a user interface tool including one or more features of a building and receives inputs indicating a boundary of the building, a predetermined equation parameter, (iii) an initiating device assigned to a space defined by the boundary, and a signaling device assigned to the space defined by boundary. The association mapper generates a response function defining a response of the signaling device to a detection signal outputted by the initiating device based on the inputs, and outputs instructions to at least one of the signaling device and a fire control panel that controls operation of the signaling device to cause the signaling device to execute the response defined by the response function in response to the detection signal.

    Abstract: A gunshot detection system provides integration with building management systems installed in a common building. Distributed devices of the building management systems (e.g. light fixtures, smoke detectors, thermostats, exit signs) are positioned throughout the building, and gunshot sensor units of the gunshot detection system are incorporated with, attached to and/or combined with the building management distributed devices. The gunshot sensor units share a common housing with the distributed building management devices, attach to the devices via attachment mechanisms, and/or are incorporated into hybrid devices that include gunshot sensor and building management elements. The gunshot sensor units might comprise reflectors for collecting and focusing sound waves onto microphones of the gunshot sensor units. These reflectors could be existing parts of building management devices, or common housings for the gunshot sensor units and the building management devices, and/or parts of the gunshot sensor units independent of the building management devices.

    Abstract: A gunshot detection system takes advantage of existing fire alarm system infrastructure by tapping a fire alarm communication network for a fire alarm system. Gunshot sensor units and/or a gunshot detection control panel receive power from the fire alarm communication network via tap units and/or tap wires, which provide electrical connectivity between the fire alarm communication network and the devices of the gunshot detection system. At the same time, the gunshot detection devices communicate via wireless links to an ancillary high-speed network. The gunshot sensor units can communicate with the fire alarm control panel via the fire alarm communication network. Even more comprehensive integration with the fire alarm system involves a hybrid gunshot detection and fire alarm control panel for controlling devices of both the gunshot detection system and the fire alarm system. Hybrid gunshot sensor units include fire detection elements such as smoke sensors and/or fire notification elements.

    Abstract: A gunshot detection system continually monitors ambient noise throughout a building, learns the building's auditory patterns, and alerts users when sounds are found to be unusual or generally indicative of a dangerous situation. For example, gunshot sensor units positioned throughout the building include microphones. During a learning period (e.g. during normal conditions), these microphones capture ambient noise. The gunshot detection system generates ambient noise models representing the ambient noise during the normal conditions. The gunshot detection system then continually processes currently captured audio data depicting ambient noise (and potential acoustic anomalies) against the ambient noise models to detect and/or identify the acoustic anomalies and to determine whether to generate an alert.
