General Description

The LCP-100A Level Control Panel gives keypanel opera­tors direct access to the crosspoint gain adjustment feature
of the intercom system. It lets them adjust the individual
listen levels for 16 keypanel or expansion panel keys.

Upgrade EEPROM

The LCP-100A is compatible with all KP96, KP97, and
KP98-7 Keypanels. However, the supplied keypanel
EEPROM may need to be installed in some cases. Since the
EEPROM is different for each keypanel model, the
LCP-100A is packaged under three different catalog num­bers. See Table 1. The following paragraphs summarize the
keypanel model and EEPROM version identification, and
the procedure to replace the EEPROM. Note that the new
EEPROM changes the keypanel DIP switch functions as
summarized on page 2.

Keypanel EEPROM Version Identification

Keypanels with programming keypad: Tap key se­quence CLR-0-8. Then use the scroll up or down key to
locate the version number. It will be something like V82 or
V83G etc.

Note: If you are not able to determine the version with this
key sequence, or if the keypanel does not have a program­ming keypad, replace the EEPROM.

EEPROM Replacement

Table 2. KP96/97 DIP Switch Summary

Use normal precautions when handling static-sensitive de­vices.

1. Unplug the keypanel power cord.

2. Remove the screws from the top cover.

3. Locate the old EEPROM (U305). Observe the orienta­tion of the old EEPROM, then remove it and install the
new EEPROM in the same orientation.

4. Replace the top cover and reconnect power.

KP96/97 Keypanel DIP Switch Functions after
EEPROM Replacement

Refer to Table 2

and the following descriptions.

☞ Important: Any time you change the DIP switch

settings you must turn the power off-then-on to reset.

Combinations of Expansion and Level Control Panels:

Dip switches 1 and 2 select the various allowable combi­nations of expansion panels and level control panels that
can be connected to the keypanel.

Winking On / Off: DIP switch 3 turns the winking feature
on or off. When winking is on, the LED in each listen key
will wink when the talk key directly beneath it is on. This
provides a visual reminder of any active talk paths. For
some people, this may be distracting and the feature may
be turned off.

Keypanel Address: DIP switches 4-7 set the keypanel
address as before. See Table 4

for address numbers.

Keypanel Baud Rate: Dip switch 8 sets the baud rate as
before.

Talk Key Row Selection: You can select whether you
want the talk keys to use the top row (above the displays)
or the bottom row. See DIP switch 1 settings.

Expansion Panel In-use Indication for IFB and ISO:

The KP98-7 provides a flashing display indication when
an IFB or ISO is in-use by another keypanel. Generally,
the keypanel operator can distinguish this from an incom­ing call for two reasons: first, the flashing indication is
slower than an incoming call indication; second, an IFB or
ISO will generally have a distinctive name, and since calls
are not normally received from an IFB or ISO, the
keypanel operator is able to conclude that the flashing in­dication is not an incoming call.

EKP98-0 expansion panels connected to the KP98-7 are a
different matter, however, since they use illuminated but­tons without alphanumeric displays and cannot display
names. In this case the keypanel operator can only distin­guish between an in-use indication and an incoming call
indication by the speed of the button flash. If this creates
confusion, disable the flashing in-use indication by setting
DIP switch 2 to the “closed” position.

LCP Selection: If a level controlpanelwill be connected for
use with the KP98-7, set DIP switch 3 to the “Closed” posi­tion. Otherwise, leave this switch in the “Open” position.

Keypanel Address: DIP switches 4-7 set the keypanel ad­dress as before. See Table 4 for address numbers.

Operation Notes

KP96/97 Keypanels

Keypanel operation is described in the KP96/97 Operating
Instructions Manual. Note that the MVOL feature is no
longer applicable with the updated firmware. To adjust the
listen level for any keypanel key, rotate the corresponding
control on the LCP-100A.

KP98-7 Keypanel

Keypanel operation is described in the KP98-7 Operating
Instructions Manual. Note that the MVOL feature is no
longer applicable with the updated firmware. To adjust the
listen level for any keypanel key, rotate the corresponding
control on the LCP-100A.

The EKP98-0 does not have listen keys, but only has talk
keys. Therefore, it is not possible to manually activate the
listen path corresponding to any talk key. Consequently,
you should assign either the auto-listen or auto-reciprocal
special function to all listen keys. Auto-listen will force
the listen path to activate whenever the corresponding talk
key is pressed. Auto-reciprocal will force the listen path to
always be on.

Baud Rate: SW1-8 selects the baud rate as before.

Mounting

For ease of use, we recommend mounting each LCP-100A
directly above or below the keypanel or expansion panel
that it will be used with. The LCP-100A knobs do line up
with the keys on KP96/97 Keypanels and EKP96/97 Expan­sion Panels. When using the LCP-100A with a KP98-7, you
may wish to label the knobs.

Connections

KP96/97 Keypanels

Typical connections for a KP97/96 keypanel are shown in
Figure 1. A maximum of two expansion panels and three
level control panels may be connected.

KP98-7 Keypanel

Typical connections for the KP98-7 are shown in Figure 2
A maximum of one EKP98-0 and one LCP-100A may be
connected. The LCP-100A can only be used to adjust lev­els for the KP98-7.

Once you have assigned the EKP98-0 keys, you can adjust
the listen levels using the crosspoint gain feature of
ADAMedit (or ZEUSedit).
