9.0 Off-Board Points
9.1 Zonex Buses
9.1.1 POPIT Modules
The D9412GV4 can use point of protection input
transponder (POPIT) modules to provide a
maximum of 238 off-board points, bringing the
total number of points the D9412GV4 can
monitor to 246. The D7412GV4 provides up to 67
off-board points, bringing the total number of
points the D7412GV4 monitors to 75. Each off-
board point requires a POPIT Module.
The expansion bus can be shared
between fire and non-fire devices
where the POPIT module provides
data isolation between the input and
the bus connections.
9.1.2 POPEX Modules
POPITs connect to supervised two-wire data
expansion loops run from POPIT to POPIT
throughout the premises. Data expansion loops
connect to a D8125 Point of Protection Expander
(POPEX) Module. POPEX Modules have power
and data connections to the point bus on the
control panel (Table 12).

9.1.3 Missing Conditions
If a programmed POPIT is disconnected from the
expansion loop, a missing condition appears
immediately and the event is logged. The missing
condition might also be sent to a central station
or printed to an on-site printer, if programmed to
do so. Refer to the Control Panels
(D9412GV4/D7412GV4 v2.03) Program Entry
Guide (P/N: F01U265459) for programming
options.
9.1.4 Control Panel Responses to Missing
Point Conditions
D9412GV4 and D7412GV4 respond to missing
point conditions based on the point’s
programming and the turned on (armed) state of
the point’s area. For example, if an interior
motion detector point is missing during a turned
off (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.
9.2 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 D9412GV4 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 D9412GV4 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.
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
D8125 POPEX and D9127 POPIT Modules are UL
Listed for Local or Police Connected Burglar
Alarm, Central Station Burglar Alarm, Household
Burglar Alarm, Central Station Fire, Local Fire,
Remote Station Fire, Household Fire, and
Electrically Actuated Transmitter Applications.
Refer to 17.0 Approved Applications to determine
the required equipment and enclosures for the
application.
