TTP21: Extra Points on the System
A B C
Initial Actions
Understand each of the following:
• An extra point is caused by installing a hardware
point for an address without programming that
address into the control panel. This symptom
presents itself whenever the control panel CPU
resets.
• If the point expansion technology is powered from
an auxiliary power supply, ensure that the
auxiliary power supply shares a negative (-)
common reference with the control panel. Refer to
Figure 30 on page 61.
• If you programmed a D9210B Access Control
Interface Module to use an on-board point
number, you must remove the end-of-line (EOL)
resistor from that on-board point.
Procedure
1. Determine the expansion technologies connected to
the control panel. For more information, refer to
Section
4.1.1 Identifying the Point Expansion
Technologies Installed on the System on page 113.
2. Remove all but one expansion technology from the
control panel.
3. Reset the control panel using the reset pin.
4. Wait 60 seconds.
5. At the keypad, press [9][9][ENT].
6. If necessary, enter the passcode [ENT].
7. Select View Log?.
8. At the Start Date? prompt, press [ENT]. The last event
appears.
9. Press [PREV] to scroll backwards through the log.
Stop at the REBOOT event. Record all extra point
numbers in the connected expansion technology’s
column in
Table 33 on page 61.
10. Disconnect the connected expansion technology from
the control panel.
11. Connect another expansion technology to the control
panel, then repeat Steps 3 through 10 for each
expansion technology installed at the site.
Are there any extra points in the D9210B column of
Table 33?
Are there any extra points in the D8125INV column of
Table 33?
A B C
The extra point is caused by a device that is
addressed to that same point number. To locate this
device, refer to Section
4.1.4 Identifying
Addressable Points on a Circuit on page 116 and
Section
4.1.5 Locating a Particular Addressable
Point
on page 116.
On the D8125INV:
1. Enter the passcode, then press [ENT].
2. Press [DIAG].
3. Press [1].
4. Enter the number of a wireless point that is extra, then
press [ENT].
5. Refer to Item 2 in Figure 27 on page 52, and refer to
Table 27 on page 52.
Is the point “missing”?
Test each wireless transmitter until the extra point’s
value changes state. Remove the battery from that
transmitter. At the D8125INV, press [ESC] for the
main menu. Press [1]. Enter the extra point number
[ENT]. Press [2] to delete the point.
At the D8125INV, press [ESC] for the main menu. Press
[1]. Enter the extra point number [ENT]. Press [2] to delete
the point.
Is Point 256 the extra point?
The extra point is caused by assigning a point to the
D9210B Access Door without programming that point into
RADXPNTS.
1. With your RPS software or D5200 Programmer, use
RADXPNTS to create a point index. Refer to
Table 34
on page
61.
2. Assign that point index to the point by using the point
assignments section of RADXPNTS. This turns the
point on.
The extra point is caused by not assigning a point to the
D9210B, and not turning it on in RADXPNTS.
Even if you are not using the point, you must assign it to a
point number in RADXAXS, turn the point on in
RADXPNTS, and connect the EOL resistor to Terminals 9
and 10 on the control panel.
1. With your RPS software or D5200 Programmer, use
RADXAXS → Door Profile to select the access door.
2. Use the Door Point prompt to assign a new point number.
3. Use RADXPNTS to create a point index. Refer to
Table 34
on page
61.
4. Assign that point index to the point by using the point
assignments section of RADXPNTS. This turns the point
on.
If the problem still exists after completing this TTP, refer to
TTP48 Noise on Wire on page 102.
