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. 

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.  

The D9127 Module enclosures are made of UL Listed 
fire resistant material. D9127T Modules contain 
tamper switches. D9127U Modules include 
untampered covers. Unless the module is mounted in 
a tampered enclosure, UL requires D9127T Modules 
for certificated accounts.
