Problems with Points
Symptom
Diagnosis
Remedy
Point appears as
missing at command
centers and in reports
to the receiver.
POPIT is not
connected or
incorrectly connected
to the data expansion
loop.
Disconnect the EOL resitor from the loop
output of the POPIT. You should measure 8 to
13 VDC, constant.
Sensor loop switch (1
to 8) is turned off on
OctoPOPIT.
If the sensor loop switch on an OctoPOPIT is
turned off for a programmed point, the point
reports as missing.
Switch 12 ON for more
than one OctoPOPIT
connected to ZONEX.
Switch 12 ON for
OctoPOPIT
connected to same
ZONEX as a D8125.
Connect only one OctoPOPIT with switch 12
ON to ZONEX.
If ZONEX is connected to a D8125, turn switch
12 OFF for all OctoPOPITs connected to that
terminal.
POPIT is not
programmed correctly.
Verify that the switches on the POPIT are set
for the missing POPIT number. Switches set
incorrectly can cause both missing and extra
POPITs.
Points intermittently
appear as missing.
Points are erratic.
Problem with data
expansion loop.
See
Problems with Data Expansion Loop.
Debounce Count
parameter set at 1. If
an off-board point is in
transition between
normal and faulted
conditions as the
panel scans it, it
appears as missing.
Radionics recommends that the Debounce
Count be left at the default of 2.
Decreasing the Debounce Count to 1 may
cause points to appear as missing. Increasing
the Debounce may cause missed alarms.
