How does the Dialer Know Who to Call? The dialer has a System Telephone
Directory composed of up to 8 user-programmed telephone numbers. Each telephone
number in the System Telephone Directory can be up to 30 digits long, and can specify
tha the call is placed over the hardwired telephone line or via the built-in cellular module.
Special ‘*’ control sequences may be embedded within a user-programmed telephone
number. These include tone/pulse selection dialing, pauses, auto acknowledgment of an
alarm call-out, dial '*' or '#' for interfacing to telephone equipment, or to select the built-
in cellular capability to make the call. These special sequences allow a tremendous
amount of flexibility on a telephone number by number basis. For example, one number
may use the hard-wired telephone connection, while another may use the built-in cellular
module.
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 (or use the built-in cellular communications if the phone
number has *7 code indicating the dialer should dial out using the cellular interface) 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), OR, if a cellular call,
there is sufficient minutes balance in the cellular prepaid account to make a call.
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.
