TIF-2000A
TIF-2000A System Setup To Receive Calls
To the intercom system, the TIF-2000A is similar to a keypanel. If the phone lines are to be used for outgoing calls only, then no
programming in AZedit is necessary. If users are going to phone into the intercom system from the outside, then the TIF4000 needs
to be configured to allow them to use the phone line in much the same way a local user uses the keypanel.
Programing the information for the phone line is entered into AZedit just as if the TIF-2000A where an ordinary keypanel, by
selecting keys from the main menu, then selecting TIF-2000A from the drop down menu of keypanels. The TIF-2000A operates
much the same way as a keypanel, except the keys are really the DTMF buttons on the user’s telephone.
Auto-Answer Mode
To use the TIF-2000A in auto-answer mode, you must first enable auto-answer mode on the DIP switch bank, switch 1. You may
also wish to enable Password Required, switch 3. In addition, you may select the number of rings before the unit answers (internal
DIP switch #2), and the actual password (internal DIP switch #3).
When the caller dials into the TIF-2000A, they hear the line ring, then the unit answers and beeps to request the password (if
password required is enabled). The user must enter the password. The unit beeps once to confirm a proper password. If the
password is not correct, the unit beeps twice to allow another try. The user is allowed three (3) attempts to enter the correct
password, after which the TIF-2000A disconnects.
Once the password has been entered, the TIF-2000A establishes communications on key #1 automatically. From AZedit, these are
talk and listen key #1. If, for example, the user is a camera operator, it may be desirable to program the camera PL as talk and listen
on talk and listen keys #1. If the caller were a reporter, you might want to program an IFB on listen key #1but no talk key #1.
Keys 2 and 7 may also be programmed. To use the other keys from the phone, just press the DTMF button for the key you wish to
use. For example, if key #1 was the camera PL, and you have finished with the shot, you may press #1, which toggles off key 1. If
master control were programmed on key #2, you may then press 2 and call master control. Likewise, you might have an IFB
programmed on listen 3, with no talk. If you press 3, you hear the IFB. #4 could have an IFB talk on it, to allow a caller to speak on
an IFB circuit.
Each DTMF button acts as if it were on a push on/push off switch. When programming in AZedit, program the same key number
as the number the user is going to press on the telephone to speak.
Talk keys 8 to 15 have a special purpose. If you are not using auto-answer mode, but have setup the TIF-2000A to be manually
answered, talk keys 8 to 15 are programmed for the keypanels which are to receive the ring signal. They may also be toggled On
and Off from the phone by DTMF 8, so they may be used in auto-answer mode as well. You may program only key 8, in which
case it behaves the same as keys 1-7. You may also program additional keypanels, PLs, IFBs, etc. on keys 9-15, and they are
activated simultaneously by the 8 button on the phone.
Manual Answer Mode
In manual answer mode, the line rings until it is answered from a keypanel. In general, you must designate panels which are to
receive the ring, so they can answer the line. When a line is manually answered, the caller does not have to enter a password, even
if the password required switch is turned On. You may mix modes by enabling auto-answer, but setting the ring count for 8 rings. If
no user has answered the call by 8 rings, the TIF-2000A automatically answers the call, and if the password required is enabled, the
call is screened by requiring a password.
To use manual answer mode, you may choose to program keys 1 to 7 as above, if you want. When the phone is manually answered,
key 1 is not automatically activated, but the caller may activate any of the keys if he wishes.
You must also designate the panels which are going to ring when the line rings. Program these panels on keys 8 to 15, using both
L1 and L2 if you have more than 8. It is generally not necessary to program the listen keys on these positions. When the line rings,
the TIF-2000A calls these panels when the line is ringing. The TIF-2000A generates a ringing noise which is then transmitted to
these panels. The panels displays the TIF-2000A’s alphanumeric in the incoming call window (CWW), and if a talk key has already
been programmed on the panel, its alphanumeric flashes rapidly.
