2. Connect the negative (-) data terminal from
the first POPIT on the data expansion loop to
one of the D8125's negative (-) terminals.
POPIT Sensor Loops
9.3.5
The number of normally-open and normally-
closed detection devices each sensor loop can
supervise is limited only by the resistance on the
loop. Resistance on each sensor loop must be
less than 100 , not including the EOL resistor.
Certain UL and NFPA applications can
limit the number of detection devices.
Consult the appropriate UL or NFPA
standards.
POPITs detect open, shorted, normal, and
grounded circuit conditions on their sensor
loops. They send the condition of their loops to
the control panel. A ground on the sensor loop
sends a general system ground-fault condition
report. Each POPIT is programmed and sends
signals to the control panel separately.
Terminate each POPIT sensor loop with the 33 k
end-of-line (EOL) resistor (D106F) included with
each POPIT.
Use a twisted-pair wire (six twists per foot) in all
POPEX and POPIT installations for the data
expansion loop wiring and the POPIT sensor
loops. Run wires away from AC sources to
prevent AC induction. If you suspect a noisy
environment, use shielded cable. Refer to Section
9.3 Installing the D8125 POPEX Module on page
43.
9.3.6 POPIT Module Point Assignments
Six switches on each POPIT assign the module to
a point number. For POPIT switch settings, refer
to Appendix B.1
or Appendix B.2
9.3.7 Program Record Sheet
The Appendix B.1
or Appendix B.2
contains the POPIT Switch Settings for the D9127
POPITs. On the D9127T/U POPIT, switches are
numbered 0 to 6, from left to right. Set the
indicated switches to the ON position. If a dash
() appears in the switch position, set the switch
to the OFF position.

The second column contains the Translation of
the point number into the Zonex format. Refer to
Point User Flag in the
D9412GV4/D7412GV4/D7212GV4 Program Entry
Guide (P/N: F01U218312) for an explanation of
this feature.
The third column contains the Point Number as
shown at keypads.
The fourth column contains the Point Index. Refer
to Point Index Parameters in the
D9412GV4/D7412GV4/D7212GV4 Program Entry
Guide (P/N: F01U218312) for an explanation of
the point index.
The fifth column, Area Assign, shows the area to
which the point is assigned.
The sixth column shows the Debounce Count for
the point. Refer to Debounce Count in the
D9412GV4/D7412GV4/D7212GV4 Program Entry
Guide (P/N: F01U218312).
The seventh column shows the BFSK/Relay
report code, which associates a relay to an
individual point.
The eighth column contains the Custom Point
Text displayed at keypads for the point. The text
is sent to the receiver when the control panel
uses the Modem IIIa format.

POPIT Labels
9.3.8
D9412GV4 off-board points are numbered 9 to
127 and 129 to 247. The D7412GV4 uses Points 9
to 75 only. D7212GV4 off-board points are
numbered 9 to 40. The D9412GV4 reserves
Points 128 and 248 for internal use. POPITs must
be connected for Points 129 to 247 to expansion
loops connected to POPEX #2.
Two sheets of peel-off POPIT labels are supplied
with the D8125 POPEX Module. Use the sheet
marked "Bank1" for Points 9 to 127. Use the
sheet marked "Bank2" for Points 129 to 247.
Each label has two parts. Place the smaller part
(with only the point number) on the chip. Place
the larger part with the switch settings on the
base of the POPIT. Set the switches and cover
the POPIT.
Do not program two POPITs for the same point
number. After programming all the points,
perform a Service Walk Test. Refer to Section
4.11 Service Walk Test on page 47. If a point does
not test, check the programming for a duplicated
address.
