1. GENERAL DESCRIPTION
The N-8640SB is an IP door station assembly kit consisting
of Main and Sub PC boards, cables, and mounting hardware
(excluding the operation panel) of the N-8640DS IP door station.
You can make the IP door station suitable for applications using
this kit in combination with the operation panel section to be
prepared separately.
Use the N-8000 Setting Software* to perform settings. Set up the
same items as those for the N-8640DS since the N-8640SB is
handled as the N-8640DS on the software.
Settings and operations are the same as those of the N-8640DS.
For details, read the descriptions about the N-8640DS in the
N-8000 series instruction manual*.
* Available for download on the TOA product data download site
(http://www.toa-products.com/international/).

Unit: mm
• A: Case mounting sleeve position
• B: Chassis mounting sleeve position
• Sleeve height: 11 mm (from the panel’s rear surface)
• Sleeves should be metallic.
• Speaker opening size should be roughly 30% of the area of a
circle with the speaker’s diameter.
• Microphone opening size should be roughly 70% or more of the
area of a circle with the microphone’s diameter.
[Notes on the Call switch]
• Position the Call switch within the range shown above.
• The Call switch’s height should be 20 mm or less from the operation panel’s rear surface.
• The Call switch should be of momentary type.
• When the above conditions could not be satised, provide an
external call switch using the external control input cables.

Place the Case gasket onto the operation panel, then
screw the chassis and speaker bracket to the operation
panel.
Connect the connection cables and harness to the
Main PC board, then secure the Main PC board to the
chassis.
Connect the speaker and microphone connection
cables (tted with a connector) from the chassis to the
Main PC board. Connect between the Call switch on
the operation panel and Main PC board using the Call
switch connection harness.
If no Call switch is installed on the operation panel,
connect the external control input cables to the external
switch. (See Example 3 on p. 4, “Connections.”)
Secure the Main PC board to the chassis using the
sleeves.

Connect the power supply and external input/output
connection cable to the Sub PC board.
Join the connector on the Sub PC board and that on the
Main PC board together, then screw the Sub PC board
onto the sleeves.

Run the connection cables through the case’s cable
entry holes, then make cable connections.
Run the LAN connection cable through the case’s
cable entry hole on your left, then connect it to the LAN
connector on the Main PC board.
Run the power supply and external input/output
connection cable connected to the Sub PC board in step
3 through the other cable entry hole from the inside of
the case, then pull it out.

To network
Connecting the station to a PoE (Power over Ethernet)
Note:
switching hub compliant with IEEE802.3af eliminates
the need for an AC adapter.

or the equivalent.
As for the usable adapter,
consult your TOA dealer.
To AC mains
Be sure to ground the N-8640SB's frame ground terminal.
Also ground the electrical box if used.
