Introduction
The STG-821W is a battery rechargeable personnel tag. The STG-821W transmits LF signal periodically to establish
close range communication between tags. Leveraging on this unique tag-to-tag communication technology, the
STG-821W can also be configured for contact tracing applications to help organizations accurately track, trace
and monitor personnel, including staff, visitors and patients, coming into proximity contact with each other.
When the tags pass by a location LF exciter, it will receive the location ID transmitted from the exciter. When
there is a change of status or location, the tag will transmit RF signal to RF receiver to update status and location.
The 2 buttons on the tag allow for several configuration possibilities ie. staff assistance, panic / duress alert, alert
acknowledgment etc.
