Talk+Auto-reciprocal (AR) Listen Key Assignment:
The down position activates talk. Listen is always on and
continuously monitors whatever is assigned to the talk po-
sition.
All Call (AC) Talk Key Assignment: When a talk key is
assigned as an All Call key, it operates only as a switch to
turn on or off all talk keys to the left of the All Call key.
These other talk keys will then activate according to the
way they have been assigned. Note that will also affect
any listen keys that have been assigned with special func-
tions. For example, an auto listen key will also activate if
its corresponding talk key has been activated by an All
Call key.

Intercom Key Indications
Talk Indicator:
I
Continous green indication: Talk is activated for
normal intercom communication.
I
Green flash: Incoming intercom call indication.
The person assigned to the key is calling. Activate
the key to talk back.
I
Continuous red indication: This indication can oc-
cur for an IFB or ISO key when the key is off. It
can also occur for a key that is assigned to talk to a
remote intercom system when the key is off (inter-
com systems with optional trunking only). The
continous red indication means that someone else
is currently talking to that IFB, ISO, etc. If you ac-
tivate the key, you may break in on a conversation
that is in progress.
I
Red flash: This can occur in two circumstances:
1) When you activate a key to talk to an IFB or a
remote intercom system. The red flash occurs if
some other keypanel with a higher priority is
currently talking. You cannot talk at this time.
2) When there is an incoming telephone call to a
key that is assigned to a TIF-951 Telephone
Interface. Activate the key to talk back.
Listen Indicator:
I
Solid green: Listen is activated. (This indication
will only be provided when you manually turn lis-
ten on by tapping or pressing upward on a key. It
will not occur if listen has been automatically acti-
vated during talk.)

CALL WAITING OPERATION FOR
INCOMING CALLS
As previously described, the talk indicator for a key will
flash when there is an incoming call to that key, and you
may activate that key to talk back. Also, if DIP switch 1
(page 9) was set to the Open position, the caller's name
will appear in the call waiting window, and you may press
down on the call waiting key instead to talk back. If a
caller is not already assigned to an intercom key, the call-
er's name will always appear in the call waiting window,
and you must use only the call waiting key to talk back.
If a second call is received in the call waiting window
while a caller's name is already displayed there, the call
waiting display will start to flash. Also, the topmost LED
next to the call waiting key will turn on. When there are
multiple calls, use the call waiting key as follows:
1.
To talk to the currently displayed caller, press down
on the call waiting key.
2.
To clear the currently displayed caller name, briefly
tap up on the call waiting key. The next caller's name
will then appear in the call waiting window, and you
may press down on the call waiting key to talk back.
3.
Continue talking to callers and clearing their names
until the call waiting window displays dashes (no
callers). Also, when all calls have been answered, the
green LED next to the call waiting key will turn off.

MKP-4 OPERATION WITH THE TIF-951
TELEPHONE INTERFACE
If DIP switch 3 (page 9) is set to the Open position, you
can use the MKP-4 to answer incoming telephone calls
that have been received by the TIF-951. A talk and listen
key pair on the MKP-4 must be assigned to talk/listen to
the TIF-951 as previously described. Use the assigned
keys as follows:
1. Leave the talk and listen keys in the off position,
except when answering a call.
2. When there is an incoming phone call, the talk
indicator will flash red. Activate the talk key to talk
back. You may also have to activate the listen key.
3. When the conversation is finished, turn the keys off.
Important! The MKP-4 does not hang up the phone
line when you turn the keys off. Usually the TIF-951
does this by detecting when the caller has hung up.
However, this may not be possible in some phone
