D7212GV3 Responses to Missing Point

Conditions

The D7212GV3 responds 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. Points 9 to 40 connect to
the POPEX Module. The control panel annunciates
activity only for each POPIT, not for each detection
device connected to the sensor loop.
Both 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.
Listings
The D8125 POPEX and the D9127 POPIT Modules
are UL Listed for Local or Police Connected Burglar
Alarm, Central Station Burglar Alarm, Household
Burglar Alarm, Household Fire, and Electrically
Actuated Transmitter Applications.
Refer to the D7212GV3 Approved Applications
Compliance Guide (P/N: F01U143080) to determine
the required equipment and enclosures for the
application.
Additional Information
When the data expansion bus restores, Pt
Bus Restore event occurs. If any POPIT is
connected to the data expansion bus
without an assigned Point Index, an Extra
Point event occurs.
