1.5.2.4 EXT MIC IN (KP-96-RC Option Only)

An external microphone can be connected. The external

microphone may be used with or without a front panel

gooseneck microphone of the same type. (Internal

keypanel jumpers J404-J406 must be set for the type of

microphone (see Setting the Internal Jumpers, Section 2).

1.5.2.5 EXT LINE IN (KP-96-RC Option Only)

An external balanced audio source, such as program

sound, can be connected. The source input must be at a

nominal line level of +8dBu.

1.5.2.6 MIC PRE OUT (KP-96-RC Option Only)

This connector provides a balanced mic output signal of

+8 dBu at 60 ohms. As supplied, the MIC PRE OUT

signal is activated only when a

Talk

key is pressed. If you

want this output to be on continuously, you must reset

internal jumper J403 (see Setting the Internal Jumpers,

Section 2).

1.6 POWER-UP AND OPERATIONAL

CHECK

1.6.1 POWER-UP SEQUENCE

Plug in the ac power cords on the keypanel and any

connected expansion panels.

Turn on the power switches on the keypanel and any

connected expansion panels. Observe the power-up

sequence:

1.6.1.1 Keypanels with Alpha-Numeric Displays

When power is turned on, all alpha-numeric displays will

first display asterisks (

****

) then dashes (----). After a

few moments, the

Talk

key assignments will display. If

Talk

key assignments have yet been programmed, the

displays will continue to show dashes (----).

If the keypanel cannot establish data communications

with the intercom system, the alpha-numeric displays will

continue to show asterisks (

****

). Check the data line

connections.

If the keypanel displays random characters in the

alpha-numeric displays, DIP switch SW1-1 on the rear

panel may be incorrectly set. If the alpha-numeric

displays of any connected expansion panels display

random characters, DIP switch SW1-2 on the rear panel

of the main keypanel may be incorrectly set.

If the keypanel does not display the expected key

assignments, or there is no audio to the keypanel from

other keypanels, this indicates that the rear panel DIP

switch settings for logical keypanel number may be

incorrectly set. Recheck the settings.

1.6.1.2 Keypanels with LED Displays

The LED’s will remain off. The

Incoming Messages

display will first display asterisks (

****

) then dashes

(----).

If the keypanel cannot establish data communications

with the intercom system, the

Incoming Messages

display will continue to show asterisks (

****

). Check the

data line connections.

If the

Talk

key LEDs on the main keypanel blink

randomly, or some LEDs remain on even when there are

no calls to the keypanel, DIP switch SW1-1 on the rear

panel may be incorrectly set. If the

Talk

key LEDs on any

connected expansion panels blink randomly, or some

LEDs remain on even when there are no calls, DIP switch

SW1-2 on the rear panel of the main keypanel may be

incorrectly set.

If the keypanel

Talk

key LED’s periodically turn on

briefly (this may occur at intervals of one or two

minutes), or there is no audio to the keypanel from other

keypanels, this indicates that the rear panel DIP switch

settings for logical keypanel number may be incorrectly

set. Recheck the settings.
