Sensor Units (SU) are installed throughout the facility in concealed, protected locations, such as pipe chases. The Flare RTLS runs on a dedicated TCP/IP-based network. PoE switches provide power, network communications, and support for a centralized UPS. Being IP-based, different network media can be used for connections between buildings (e.g. fiber). Flare software runs on standard PC hardware and provides a top-level site overview as well as a zoomed-in view for active alarms.
