5 Once the test is complete, do one of the following:
• If the system is to loopdown but remain armed, send the IR (Intelligent Repeater) LPDN code (universal
loopdown).
• If all the equipment is to be looped down, disarmed and returned to normal operation, send the disarm
inband code 11100 or the ESF-DL code (FF24).
The Time-Out Override function is only valid for the current active loopback. The automatic
time-out timer is restored during subsequent loopback sessions.
The Armed mode has an automatic time-out of 120 minutes, but this timer is reset to 120 for any
of the following events:
• Loopback terminates (manually or time-out)
• Query
• Alternate query
• Far End activate
• Another ARM command
This timer is inhibited while any of the valid command codes are being sent. Once the codes
are removed, the timer restarts at 120.
