1. Introduction
The STG-821 is a battery rechargeable personnel tag. The STG-821 transmits LF signal continuously to
trigger close proximity communication between tags. Leveraging on this unique tag-to-tag proximity
detection technology, the STG-821 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.
