c) the system picks up the telephone line again and searches for a dial tone for 5
seconds
d) the system will then dial regardless of the presence of dial tone
If there is no initial handshake recognized within 40 seconds the system will then
hang up the line.
If the Force Dialing option is disabled, each attempt will still follow the above pat-
tern, except that the system will not dial in step (d) if no dial tone is detected.
The Delay Between Dialing Attempts timer adds a delay before the next call is
dialed.
If the Busy Tone Detection option is enabled, the system will hang up after
detecting busy tone for 5 seconds and will redial after the amount of time pro-
grammed in the Delay Between Dialing Attempts section.
If DTMF Dialing is enabled the system will dial using DTMF (Touch-Tone). If Switch
to Pulse Dial is enabled the system will switch to pulse dialing on the 5th attempt
to call the central station. If disabled the system will always dial DTMF.
If DTMF Dialing is disabled the system will always pulse dial.
The Post Dial Wait for Handshake determines the amount of time the system
will wait for a valid handshake from the receiver. If the system does not hear the
handshake it will consider the call a failed attempt, hang up and try again.
The Maximum Dialing Attempts determines the maximum number of attempts
the system will make to send a signal to the central station before indicating a Fail-
ure to Communicate (FTC) trouble condition. The 3rd telephone Number can be
used to back up the 1st in this situation (see 2.3.9 Communicator Telephone
Numbers on page 43).
When Bell on FTC when Armed is enabled, a failure to communicate (FTC) during
the armed period will sound an audible alarm for the length of Bell time-out, or
until the system is disarmed. If FTC Trouble Only when Armed is enabled, only
the keypad buzzer will sound trouble beeps every 10 seconds until a key is pressed.
The Pulse Dialing Make/Break Ratio option can change the Make/Break ratio to
33/67 from the North American ratio of 40/60.
With ID Tone Enabled the system will pulse a tone on the telephone line to indi-
cate that the system is on the line.
The 2100Hz/1300Hz ID Tone option selects the frequency of the ID tone that is
pulsed on the line.
If you enable the Standard Communications Priority option, the NT9010 system
will only disconnect DLS and Talk/Listen sessions for alarm and Priority (FAP) events
that are programmed to communicate. If the UL Communications Priority option
is enabled, the NT9010 system will disconnect DLS and Talk/Listen sessions on any
event programmed to communicate, with the exception of Test Transmissions and
System Tests.
NOTE:
Contact your local telephone company to confirm which settings
should be used.
