Problem; To provide an evacuation guidance system which is capable of safely and reliably guiding evacuees in response to the outbreak and spread of a fire.

Solution; An evacuation guidance system is configured from multiple sensor modules 20, network lines 30, guidance indicators 40, and a guidance control device 50. Each sensor module includes multiple input/output port pairs, fire detection sensors, and a data control unit. The multiple input/output port pairs are connected to input/output port pairs of other sensor modules by means of network lines, thereby configuring a mesh-like autonomous network. The data control unit: generates and outputs fire data after adding fire location data; upon receiving fire data, outputs the fire data after adding its own route flag; and stops the output of fire data when the fire data contains its own route flag. Upon identifying the location of the fire outbreak from the fire data, the guidance control device calculates optimum evacuation routes and causes the guidance indicators to turn on/off or flash.

Devices, methods, and systems for a self-testing fire sensing device are described herein. One device includes an adjustable particle generator and a variable airflow generator configured to generate an aerosol density level, an optical scatter chamber configured to measure a rate at which the aerosol density level decreases after the aerosol density level has been generated, and a controller configured to compare the measured rate at which the aerosol density level decreases with a baseline rate, and determine whether the self-testing fire sensing device requires maintenance based on the comparison of the measured rate at which the aerosol density level decreases and the baseline rate.

A gunshot detection system includes gunshot sensor units with microphones for detecting gunshots and capturing audio data depicting the detected gunshots and other ambient sounds, an environmental board with various environmental sensors for generating environmental data indicating environmental conditions. The audio data, environmental data, and position information can be stored locally on local nonvolatile storage of the gunshot sensor unit for later retrieval by law enforcement entities. In one embodiment, the gunshot sensor units include a wired and/or wireless data transfer interface for transferring the audio data, environmental data and/or position information to handheld units of law enforcement entities. The gunshot sensor unit can also stream live captured audio data for live monitoring by a control panel, and might also include speakers for providing audio playback of audio data from the control panel.
