9.1.1 POPIT
Modules
The D9412GV3 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 D9412GV3 can monitor to 246. The
D7412GV3 provides up to 67 off-board points,
bringing the total number of points the D7412GV3
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 10).

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 D9412GV3/D7412GV3 Program Entry
Guide (P/N: F01U170807) for programming options.

9.1.4 Extra
Point
Events
Extra Point events are generated when a POPIT
connected to the data expansion bus does not have
an assigned Point Index. Table 11 shows when an
Extra Point event is or is not generated. Table 12 on
page 37 shows additional error conditions that can
occur for the off-board points.
