This feature programs the maximum length of a call if no
other disconnect features are used. The valid entries are
1–99, representing 1-minute increments and 0
representing 4.5 hours. The call duration timer begins
when the emergency telephone goes off-hook. The
emergency telephone automatically disconnects after the
programmed time-out period elapses.

HELP
button to
reconnect the autodial number. This feature helps
prevent non-emergency calls from tying up emergency
lines for long lengths of time.
