Abstract: Devices, systems, and methods for public address system commissioning are described herein. In some examples, one or more embodiments include a computing device comprising a memory and a processor to execute instructions stored in the memory to communicate an audio file to a controller of a public address system of a facility, wherein the audio file is configured to be played by a speaker of the public address system, receive a recording of the played audio file, compare values of a plurality of audio parameters associated with the recording to target values of the plurality of audio parameters, and modify an audio setting on the controller of the public address system based on the comparison.

Abstract: Devices, systems, and methods for system gateway analysis are described herein. In some examples, one or more embodiments include a mobile device comprising a memory and a processor to execute instructions stored in the memory to scan a building system gateway of a control system, generate gateway data about the building system gateway from the scan, transmit the gateway data to a remote computing device, receive, from the remote computing device, supplemented gateway information for the building system gateway, and generate, based on the supplemented gateway information, a system gateway analysis.

Abstract: A system for monitoring a gas leakage incident in an industrial facility comprises a local area network, and a plurality of closed-circuit television cameras operatively connected to the local area network. The closed-circuit television cameras are positioned to provide video images of plural areas in a facility, with a central station operatively connected to the network for receiving video images from the television cameras. As plurality of gas detectors positioned in plural areas of the facility are operatively connected to the local area network, with each gas detector being operable to provide a signal which indicates occurrence of a gas leakage incident. Real-time monitoring of one or more gas-leakage incidents facilitates efficient evacuation of operating personnel, with the system preferably configured to automatically direct one or more of the closed-circuit television cameras to the area from which a gas leakage signal originates.
