INSTALLATION MANUAL
DOOR STATION BOARD
1. GENERAL DESCRIPTION
The N-8050SB is a printed circuit board unit for the N-8050DS Door
Station. You can make the door station suitable for applications using the
N-8050SB in combination with the operation panel section to be prepared
separately.
Use the N-8000 software* to perform settings. Set up the same
items as performed to the N-8050DS since the N-8050SB is
handled as the N-8050DS on the software.
The call button and status indicator operations are exactly the
same as those of the N-8050DS.
For settings, functions, and operations, read the descriptions
about the N-8050DS in the N-8000 Series instruction manual.
* Included in the CD supplied with the N-8000EX/8010EX
Exchange.

3. MOUNTING TO A METAL CASE OR PANEL
3.1. Installation Precautions
•
To prevent a malfunction or breakdown due to static electricity, be sure
to use a metal case or metal panel.
• Cover the whole board with a case when installing.
3.2. Speaker and Microphone Installation
•
To prevent acoustic feedback, attach the speaker and microphone closely
to the panel and position them at least 16cm away from each other's center
as shown below.

Speaker
•
Speaker opening ratio should be 15% (Example: ø4 mm x 9 holes) as a
guide.
•
Keep the board from coming in contact with the speaker to avoid short-
circuit between them.
•
Make a microphone opening with the microphone rubber's inside diameter
(ø4.5 mm), and position the microphone in the way that its center comes to
the opening center.
•
Never install them as shown below. Doing so may cause the speaker
sound to enter the microphone.
