- Password length DIP Switch Settings
ONE TOUCH DIAL
Switch 5 enables/disables the One Touch Dialing
feature. When the switch is in the OFF position, One
Touch Dial is disabled. When the switch is in the ON
position, One Touch Dial is enabled.
One Touch Dial works as follows:
If a number is stored in Auto Dial memory 1 on the
TIF-4000, and the line is on-hook, then the TIF-4000
will autodial the number stored in Auto Dial memory 1
whenever any keypanel closes a point-to-point talk key
to the TIF-4000.
FAST SEIZE
Switch 6 enables/disables the Fast Seize feature. If
the switch is in the OFF position, Fast Seize is dis-
abled. If the switch is in the ON position, Fast Seize is
enabled. If Fast Seize is enabled and the unit is set to
auto answer, then the TIF-4000 will answer or “seize”
the line at the start of the first ring.
It is important to
note that a ring will not be heard on any of the
keypanels.
DSP FULL OR HALF DUPLEX SELECTION
Switch 7 determines either full duplex or half duplex
operation. If the switch is set to the OFF position, the
DSP is forced into full duplex mode as determined by
the setting of switch 8 on the DIP switch bank located
on the rear panel of the TIF-4000. See
Full Duplex
Method
for more information. If the switch is set to the
ON position, the DSP is never forced into full duplex.
AUDIO DUCKING
Switch 8 enables/disables the Audio Ducking feature.
If the switch is set to the ON position, Audio Ducking is
disabled. If the switch is set to the OFF position, Audio
Ducking is enabled. The Audio Ducking feature helps
eliminate feedback between the intercom system and
the telephone line.
Internal DIP Switch (S203)
Internal DIP switch (S203) select the password. It has
no effect unless password required has been enabled
on the DIP switch located on the rear panel. When
password required is enabled, the password must be
entered via DTMF by the caller before they may
communicate. This is to prevent unauthorized use of
the intercom by callers. (See Table 5.)
Switches 7 and 8 select the length of the password,
from 1 digit to 4 digits. If set for 1 digit only, the first
digit of the password used , if set for 2 digits, then the
first 2 digits are used, etc. See Table 4.
Connections
INTERCOM
Use either of the “To Matrix” connectors (but not both)
to connect to an intercom port. The intercom port that
you connect to will determine the address of the unit
(see Setting Address). Cable wiring diagrams are
shown in Figure 6 and 7. An LED labeled “Data” is
located on the front card and serves as a basic
indicator of data being present.
TELEPHONE AND TELEPHONE LINE
There are two telephone connections provided on the
rear of the TIF-4000. Plug the telephone line into the
jack labeled “Phone Line”. You may also plug a stan-
dard telephone into the jack labeled “Loop Thru”.
NOTE
: The standard telephone plugged into the “Loop
Thru” jack is disconnected when the TIF-4000 seizes
the telephone line.
Relay
Simply put, a relay is a switch that is OPEN or
CLOSED. In the case of the TIF-4000, when it is off-
hook (a call is active), the switch is closed and an
indicator, such as an external lamp, can be activated.
