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.
