Are any D9210B Access Control Interface Modules
connected to the control panel?
The on-board point is not working or is not
programmed correctly. Refer to TTP16 Point
Trouble on One of the Eight On-board Points
on page
57.
1. Using RPS software or your D5200 Programmer,
select RADXAXS → Door Profile.
2. Record the point number assigned to each
D9210B that is connected to the control panel
by viewing the Door Point prompt.
Is the affected point number assigned to a
D9210B?
The on-board point is not working or is not
programmed correctly. Refer to TTP16 Point
Trouble on One of the Eight On-board Points
on page
57.
Is the same point number assigned to more than
one D9210B?
The D9210B is not working or is not
programmed correctly. Refer to
TTP15 Point
Trouble and there are D9210B Card Access
Interface Modules Connected to the Control
Panel
on page 55.
You must assign all D9210B modules a unique point
number. Once you do this, you must also use RPS
software or the D5200 Programmer to view
RADXPNTS and complete the programming of the
point.

Table 54 Point Configuration MatrixExamine on page 117.
Do any rows in Table 54 identify a point used by more
than one point expansion technology?
The point expansion technology is either not working
or not programmed correctly. If the affected point is
connected to:
• a D8128C or D8128D OctoPOPIT Module, refer
to
TTP11 on page 26.
• a D8125 Zone Expansion Module, refer to TTP12
on page
30.
• a D8125MUX Multiplex Bus Interface, refer to
TTP13 on page 37.
• a D8125INV Wireless Interface Module, refer to
TTP14 on page 48.
• a D9210B Access Control Interface Module, refer
to TTP15 on page 55.
• one of the on-board points, refer to
TTP16 on
page
57.
There are points that share a common address. You must
assign each programmed point in the control panel a unique
addressable point. This requires changing one of the
duplicate addressable points to an unused programmed
point, and changing the programming in RADXPNTS to
match.
