12.7.1 Extra Points
If the control panel is not in the Service Walk Test Mode when an extra point trips, it responds to the trip as a local
Trouble event at the command center or central station (see the Routing section in the Program Entry Guide). The
control panel shows the custom text for the point number set in the point’s DIP switch or the on-board point
location.
When an extra point is tripped during the Service Walk Test, it reports as an Extra point in the control panel’s Event
log and at the local printer (if installed). Once an extra point is identified, check the programming to see if it has a
point index programmed. Then you can determine if the point index is appropriate for the application and the area
assignment is correct.

Problem Diagnosis Solution
There is a short on the D8125
POPEX Module’s data expansion
loop or short on control panel’s
ZONEX data terminals (25 and 26,
or 27 and 28). A short on either the
Data Expansion Loop or the ZONEX
data terminals generates a PT Bus
Trouble Report. While the short
remains, the control panel responds
as though the sensor loop for each
point connected to the POPEX
Module was shorted.
Check the wiring for shorts.The control panel transmits PT Bus
Trouble Reports. Erroneous alarm
and/or trouble reports may follow a
PT Bus Trouble Report. Erroneous
alarm and/or trouble events for off-
board points appear at command
centers.
The POPIT address switches are set
incorrectly (for points 128 or 248) or
the OctoPOPIT address switches
are set incorrectly.
Confirm all POPIT and OctoPOPIT
address switches are set correctly.
POPITs cannot be used for points 128 or
248, which are reserved for panel
functions. D8128C OctoPOPITs cannot
be used for points 121 to 128 or 241 to
248. D8128D OctoPOPITs cannot use
points 128 or 248.
There is a short on the Aux Power,
Terminal 3 or ZONEX power,
Terminal 24.
Terminals 3 and 24 share a common
circuit breaker. Check the wiring and
devices connected to these terminals for
shorts or grounds.
All off-board points are MISSING.
If only one POPEX Module is
connected to the control panel, the
POPEX Module might be incorrectly
connected to the control panel or
Data Expansion Loop might be
disconnected from POPEX Module.
Check the POPEX Module for correct
connections to the control panel and the
Data Expansion Loop.
If you find missing points, the Service
Walk Test can help diagnose the problem
(see
Extra Points
below).
Keyswitch points (P## Type is
programmed as 4, 5, 6, 7, or 9)
report as missing. If the area is
armed, the point reports a Missing
Alarm. If the area is disarmed, the
point reports a Missing Trouble.
Point is disconnected from the SDI data
bus. The POPIT cover might be removed
and not replaced or the cover is not
seated properly.
The point restores when the SDI bus is
reconnected or when the POPIT cover is
seated firmly on the POPIT.
The connected points show as extra
points when the point bus is
shorted beyond the programmed
debounce time.
The points have no point index
programmed.
This is corrected when the short returns to
normal.
