DSC TL280 - Page 19

This section may be used by the installer to force the communicator to send an immediate test transmission to specific receivers,
to verify that the communications paths are available. Diagnostic test transmission failure will indicate as FTC trouble (yellow
LED = 9 flashes). If an FTC error occurs when testing all receivers, select only one receiver and repeat test to isolate the
receiver that is not communicating.
NOTE: Sending a test transmission to a receiver that is not programmed generates FTC trouble.
