TTP15: Point Trouble and there are
D9210B Card Access Interface
Modules Connected to the Control
Panel
A B C
Initial Actions
Check that there is no EOL resistor connected to the
on-board point of the control panel that corresponds
to the point number assigned to the D9210B Card
Access Interface Module. For example, if the D9210B
is assigned to Point 8, ensure that there is no EOL
resistor connected to the control panel’s on-board
Point 8.
Procedure
Is the affected point “missing”?
1. Using RPS software or your D5200 Programmer,
select RADXAXS → Door Profile.
2. Identify the door number that the affected door is
assigned to by viewing the Door Point prompt
for each access door.
3. Locate the D9210B Access Control Interface
Module for the affected access door. Refer to
Table 30 to identify the D9210B by its DIP
switch address.
Is the card reader’s tamper wire connected to
Terminal 8 on the D9210B?
1. View point assignments for the point you
are troubleshooting and determine which
point index the point uses.
2. View that point index.
3. Determine the Type and Point Response
(for more information, refer to
Table 31 on
page
56.
Is the point programmed to respond as
desired?
Fix the programming problem.
Set your digital voltmeter (DVM) for VDC.
Connect the red lead to the D9210B’s
Terminal 10 ZN+. Connect the black lead to
the D9210B’s Terminal 9 ZNCOM. For more
information, refer to
Figure 29 on page 56.
Does the DVM read <2.0 VDC or >3.0 VDC?
There are duplicate points installed on
the system. To troubleshoot this
problem, refer to
TTP20 Point Indicates
a Short Circuit When It Is Open
on
page
59.
A B C
Remove all wires from the D9210B Terminals 9
and 10. Set your DVM to read resistance.
Connect the red DVM lead to Terminal 10 ZN+.
Connect the black lead to Terminal 9 ZNCOM.
Does it show <900 Ω or >1.1 kΩ?
Connect a 1 kΩ resistor to Terminals 9
and 10 on the D9210B. Repeat the
voltage check.
Does the DVM still show <2.0 VDC or
>3.0 VDC?
There is a wire shorted to ground
on the system wiring. Refer to
TTP49 Wire Shorted to Ground on
page
106.
Remove and replace the D9210B Card
Access Interface Module.
There is a wiring problem:
• If the voltage check shows <2.0 VDC, refer
to
TTP46 Shorted Wiring on page 98.
• If the voltage check shows >3.0 VDC, refer
to
TTP47 Open Wiring on page 100.
Remove the card reader’s Tamper wire from the
D9210B’s Terminal 8. Only use this terminal for the
D9210B’s enclosure tamper. For more information,
refer to
Figure 29 on page 56.
Refer to TTP4 on page 18.
