4.1.2 Problems with Points (continued)
System Diagnosis Remedy
Sensor Reset pressed at the time
the alarm
or trouble was generated.
The D9412/D9112 ignores input from all points in the same area
programmed for sensor reset during sensor reset.
Faulted points do not
generate alarms or
troubles as
programmed.
Two points are programmed with
the same address.
Points programmed with the same address do not function
correctly. Check to be certain that you have not duplicated point
addresses.
Short on D8125 POPEX module’s
Data Expansion Loop or short on
D9412/D9112 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 panel responds as though the sensor
loop for each point connected to the POPEX module was shorted.
Check wiring for shorts.
Panel transmits
PT
BUS
TROUBLE
reports. Erroneous
alarm and/or trouble
reports may follow
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 (for
Points 121through 128 or Points
241through 248).
Check to be certain all POPIT and OctoPOPIT address switches
are set correctly. POPITs cannot be used for Points 128 or 248
(these are reserved for panel functions). OctoPOPITs cannot be
used for Points 121through 128 or 241through 248.
Short on Aux Power, Terminal 3
or ZONEX power, Terminal 24.
Terminals 3 and 24 share a common circuit breaker. Check 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 panel, POPEX
module may be incorrectly
connected to the panel or Data
Expansion Loop may be
disconnected from POPEX
module.
Check POPEX module for correct connections to the
D9412/D9112 and the Data Expansion Loop.
If you find missing points, the Service Walk Test may help you
diagnose the problem (see Section 4.1.2.1 Extra Points on page 38).
Keyswitch points (P##
Type programmed as
4, 5, 6, 7, or 9) report
as
MISSING
. If 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 may have been
removed and not replaced or the
cover is not seated properly.
The point will restore when the SDI bus is reconnected or when
the POPIT cover is seated firmly on the POPIT.
Connected points
show as extra points
when the POPIT loop
is shorted beyond the
programmed
debounce time.
The points have no point index
programmed.
This will be corrected when the short is returned to normal.
