These include tone/pulse selection dialing, pauses, auto acknowledgment of an alarm
call-out, dial '*' or '#' for interfacing to telephone equipment. These special sequences
allow a tremendous amount of flexibility on a telephone number by number basis.
How does the Dialer Prioritize its Calls?
When the dialer detects a new alarm condition, it will search the telephone directory,
beginning with the first number on the list, for the first valid telephone number. The
dialer will then go off-hook and begin to dial the telephone number if the following
conditions are true:
1. The Call Spacing Timer = 0, and the dialer has been on-hook for at least
the network recovery time (10 seconds).
2. The local telephone is on-hook (OFF HOOK LED is OFF).
3. The telephone line is operational (dial tone is detected).
During the dial out sequence, the dialer will implement all special control sequences
and/or call progress features embedded within the current telephone number. If the dialer
successfully connects with the called number, it will report the verbal alarm message for
each fault condition which exists.
The dialer will repeat the alarm message Five times after a call is answered. While
speaking the alarm message, the dialer simultaneously listens for a touch-tone entered by
the user at the remote phone. If it receives a valid tone, it will terminate alarm reporting,
and examine the tone received. If the user entered a ‘*’ key, the dialer will accept it as an
acknowledgment of the alarm condition. Any other keys received will not acknowledge
the alarm condition. The dialer will then indicate the acknowledge status and prompt the
user to enter a 2-digit access code.
If the user enters the correct code, access will be granted and the user may review or
program the dialer’s configuration using the touch-tone commands described in this
manual. If at any time during remote menu access the user does not enter a command
within 30 seconds, the dialer will speak a disconnect warning and hang up.
If an incorrect or no access code is entered during a timed access code entry time (10
seconds), the dialer will disconnect and initialize the system Call Spacing delay timer. If
the alarm condition(s) were acknowledged, then the snooze timer(s) associated with the
reported alarm condition(s) will be initialized with a value equal to the programmed
system Snooze Delay. If alarm conditions were not acknowledged, calls will continue to
be placed to the next telephone numbers on the list after the system Call Spacing delay
has expired.
