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
(infinite). The call duration timer begins when the emergency
telephone goes off-hook. The emergency telephone automatically
disconnects after the programmed time-out period elapses.
The user can immediately press the
EMERGENCY
button to
reconnect the autodial number. This feature helps prevent non-
emergency calls from tying up emergency lines for long lengths of
time.
