9.1.5 D9412GV3/D7412GV3 Responses to
Missing Point Conditions
The D9412GV3 and D7412GV3 respond to missing
point conditions based on the point's programming
and the armed state of the point's area. For example,
if an interior motion detector point is missing during a
disarmed state, a Missing Trouble event is generated;
however, if the point is missing while the area is
Master Armed, a Missing Alarm event is generated.
Non-fire, 24-hour points always generate a Missing
Alarm event, whereas Fire points always generate a
Missing Fire Trouble event.

D8125 and D9127 POPIT Modules

D9127 POPITs use the D8125 POPEX Module to
report to the control panel. Each D8125 supports up
to 119 POPIT points. Connect two D8125 Modules to
the D9412GV3 to bring the combined total number of
POPIT and on-board points to 246.

Points 9 to 127 connect to the first POPEX
Module.

Points 129 to 247 connect to the second POPEX
Module.

The D9412GV3 reserves Points 128 and 248 for
internal use.
The control panel annunciates activity only for each
POPIT, not for each detection device connected to
the sensor loop.
