programmed. It is up to the operator who programs the
TIF 2000 to convey to the user what to expect. If the user is
not familiar with the operation of the TIF 2000, it is best
keep the operation as simple as possible, until they are
familiar with its operation. For this reason, it is suggested
that you not use password required unless you have had
problems with nuisance calls in the past. If the TIF 2000
field user only requires one service, it is best to program
that service on key 1, enable auto answer, and disable
password required. The telephone user will then only have
to dial the proper phone number to use the interface. As they
become more familiar with its operation, you can then begin
to offer more options to the users, or begin to require a
password.
In general, it is very easy to use if the user has knows what
to expect. When calling in, if the unit is in auto answer
mode, it will answer the call after the number of rings which
have been selected. If password required is not enabled, the
unit will indicate it is ready with a single beep. If password
required is enabled, the TIF 2000 will prompt for a pass-
word with 2 beeps. The user will enter the password, and
the unit will either beep once if the password was correct, or
twice if it was wrong. The user is allowed 3 attempts to
enter the password, after which the TIF 2000 will discon-
nect. In the event a user calls the TIF 2000 when the
intercom system is either turned off or absent, the TIF 2000
will answer and prompt with 3 beeps.
Once the password is entered, the TIF 2000 will enable talk
and listen on key 1. This should be programmed ahead of
time to whatever communications the caller generally needs
first. If it is not desirable for the caller to be able to talk at
this point, then only the listen key for key 1 should be
programmed.
The caller may then either continue to use key 1, or they
may select other keys with their DTMF pad. They may turn
off key 1 by pressing DTMF 1, or may continue to just add
other keys. At any time, the caller may turn off all keys
without hanging up by pressing 0. When the call is com-
plete, the caller should enter *#, which will cause the
TIF 2000 to disconnect. This is more reliable than waiting
for the phone system to pass the disconnect information to
the TIF 2000.
DTMF Codes
Once programmed, the TIF 2000 may be operated via the
DTMF keypad on the telephone. The DTMF keys have the
following functions:
Normal Mode:
1 thru 7 Toggle on and off talk and listen #1 to #7.
Note: Initially, #1 will be enabled if the unit auto answered
the line.
8 Toggle on and off talk and listen to the panels which ring
when the line is ringing. This allows the caller to “recall”
the panels without having to hang up and redial. Toggling
this on will allow the callers voice to be heard from all
the panels which normally ring.
9 Enters programming mode, to reassign keys.
0 Turn off all talk and listen keys. Since 1-8 are toggles, it
is possible to forget which keys are “on” and which are
“off”. In this case, just press 0 to turn then all off, and
start over.
*1 thru *7
Toggle on and off listen 1-7. By pressing
* before the key, you only change the listen. This allows
you to listen to a circuit without talking to it, or to talk to a
circuit without listening to it.
Note: You will automatically listen and talk to #1 if the
TIF 2000 auto answered the line.
*8
Toggle on and off listen for 8-15.
*#
Disconnect. This will cause the TIF 2000 to hang up.
It is a good idea to do this before you hang up, as many phone
systems take a long time to signal that the far end has hung
up.
Programming Mode:
You may reprogram the talk and listen assignments on 1-7,
just as you can on a keypanel (if they are not restricted via
ADAMedit). Note that the sequences are the same as the
sequence you would use from a keypanel, except that you
must first enter programming mode by pressing 9.
Note: The use of programming mode is discouraged due to
a lack of feedback to the user to verify a programming
sequence has worked as intended.
