The TRT-300 A acts as a remote contact interface that can activate or deactivate
a third party instrument or equipment that needs to be triggered during a live-
broadcast of an evacuation event. The TRT-300 A sits in the LOOP and receives
the broadcast audio message. As soon as the broadcast audio message contains
a 20kHz pilote-tone, the on-board relays of the TRT-300 A will change state into
‘override’ mode. The state change is latched as long as the pilote-tone is received.
Depending on the function of the third party instrument or equipment, the TRT-
300 A offers two potential free NC and a NO switching contacts.
The VARES-LOOP – Ringbus Isolator (TRT-200 A) is the successor in our range of
loudspeaker loop-isolator devices that are using our patent technology to deliver a
higher level of security of evacuation loudspeaker lines that are installed according
to the return-loop principle.
