Terminals
9.1.1

POPIT Modules

The D7212GV3 can use point of protection input
transponder (POPIT) modules to provide a maximum
of 32 off-board points, bringing the total number of
points the D7212GV3 can monitor to 40. 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 9).

Extra Point Events

A POPIT connected to the data
expansion bus does not have an
assigned Point Index and:
Data expansion bus is disconnected
Data expansion bus restores to normal
condition after an open condition
Point input changes status from normal
to open or shorted
During a Service Walk Test, the point
input changes status from normal to
open or shorted
∗
The Service Walk Test never shows the electrical state of a point as "Extra."

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 D7212GV3 Program Entry Guide
(P/N: F01U170808) for programming options.
9.1.4
Extra Point events are generated when a POPIT
connected to the data expansion bus does not have
an assigned Point Index. Table 10 shows when an
Extra Point event is or is not generated. Table 11 on
page 33 shows additional error conditions that can
occur for the off-board points.
