9.3.4 Wiring Data Expansion Loops to POPEX
Modules
Each POPEX Module has two positive (+) and two
negative (-) data expansion loop terminals. Up to 32
POPITs can be connected to one D8125 on the
D7212GV3 (refer to Figure 13 on page 34).
To connect the data expansion loops to the D8125
POPEX Module:
1. Connect the positive (+) data terminal from the
first POPIT on the data expansion loop to one of
the D8125's positive (+) terminals.
2. Connect the negative (-) data terminal from the
first POPIT on the data expansion loop to one of
the D8125's negative (-) terminals.
9.3.5

POPIT Sensor Loops

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 Ω 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 kΩ
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 35.

Off-Board Points
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
Point Assignment in the D7212GV3 Program Record
Sheet (P/N: F01U170810). The program record sheet
provides information about the Point Assignments
tables. Figure 14 on page 37 is an example of the
tables.
For the D7212GV3, Points 9 to 40 can use
D9127 POPITs.
9.3.7

Program Record Sheet

The first column of the table in Figure 14 on page 37
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 D7212GV3 Program Entry Guide
(P/N: F01U170808) 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 D7212GV3 Program
Entry Guide (P/N: F01U170808) 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 D7212GV3
Program Entry Guide (P/N: F01U170808)
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
2
IIIa format.
