Real-Time Locating System

Annotation 2020-07-27 125557.jpg

To help keep personnel working in high-threat environments safe, the Flare Real-Time Locating System (RTLS) instantly identifies and locates personal duress alarms at the touch of a button. Designed for reliability in institutional and industrial environments, the Flare RTLS uses proven, cost-effective technology that has been keeping staff safe for over 20 years.

How It Works

The Flare RTLS uses patented technology that works with the building’s RF characteristics to accurately and reliably locate duress alarms. In the event of danger, the user activates a Personal Protection Device (PPD). The PPD emits an RF signal that is detected by a network of sensor units concealed throughout the building

Radio Frequency Technology

  • Uses patented technology that works with the building’s RF characteristics to accurately and reliably locate duress alarms

  • Resolves to the floor in multi-level facilities

  • Signal not blocked by smoke, heavy clothing, or the human body

  • Supports indoor and outdoor applications

  • Provides coverage in rooms, stairwells and corridors with no blind spots

Radio Frequency Technology

  • The individual activates the Personal Protection Device (PPD) with the push of a button

  • An RF signal is sent and detected by a network of sensor units concealed throughout the building

  • The location, status, and identity of the PPD appears on a map-based display in the control room

Flexible Wear Options

  • Belt-worn, Personal Protection Device (PPD) with pull-pin and man-down (tilt activated) options

  • PPD Compact that can be worn in a variety of ways, including on a lanyard, which is ideal for support and administrative staff in institutional environments as well as visitors

  • Depending on the version, the personal duress alarm is activated by a button push, pull-pin, or man-down (device tilt) event

Low Sensor Unit Density

The number of sensor units required at a site is determined primarily by location resolution requirements. For example, an industrial site where workers only need to be located to a general area will require fewer sensor units than a correctional facility where a per-room resolution is critical.

Scalable Architecture

The Flare RTLS sensor network can be extended by adding additional sensor units. The existing sensor units do not need to be moved or reconfigured. This future-proofs the system if the facility undergoes expansion or renovations.

User Identification

Each PPD is individually identified and the system can be configured to display user names or other information in the control room.

Minimal User Training Requirements

The Flare RTLS is designed to be easy to use and fit within the facility’s daily routines. The PPDs include a self-test function, making it easy for users to test their device at the start of each shift without control room intervention. The PPDs are designed for hassle-free operation and require only minimal user training.


Powered by commercial off-the-shelf batteries, the PPDs typically operate for over six months between changes*. When the charge becomes low, the PPDs generate low-battery notifications in the control room and continue to operate for at least 7 days*. (*Dependent on battery type and capacity.)

Deployment Diagram

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.
