Elpas LF Beacons add real-time pinpoint location visibility to Elpas RTLS Security, Safety & Visibility Solutions or 3rd party security management systems.

The LF Beacon is a wall or ceiling mountable low frequency emitter for use in indoor building environments. The device provides Elpas RTLS solutions with immediate location awareness that a tagged asset or person has passed through a protected doorway or a specific entrance/exit area.

The LF Beacon emits a programmable field up to 4.5m/ 14.7ft in radius and can be deployed in a primary–secondary configuration for covering double-doors or indoor lobby areas.

The Elpas LF BUS Beacon is a wall mountable low frequency emitter for indoor building environments. The device provides real-time, chokepoint location data that a tagged asset or person is near a specific door, is in a particular hallway zone or is in an explicit sub-room area.


The Beacon has a 10ft range (3m) that is adjustable to cover areas as small as 4 inches/10cm. Optionally up to four LF BUS Beacons can be deployed in primary–secondary configurations for covering large double-doors or architectural complex indoor areas.

This unique technology allows coverage of enterances and drievways up to 40M/131 feet wide. Gardens and patios with a circumference up to 80M/260 feet can be enclosed in a LF field. The beacon can be deployed in a primary–secondary configuration for covering larger areas.
