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

D7212GV2 (refer to Figure 15 on page 35).

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. Refer to the D9412GV2/D7412GV2

Troubleshooting Guide (P/N: F01U011024). 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

36. Also refer to Noise on Wire in the General Wiring

Troubleshooting section of the D9412GV2/D7412GV2

Troubleshooting Guide (P/N: F01U011024).

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 D7212GV2 Program Record Sheet

(P/N: F01U003804). The program record sheet

provides information about the Point Assignments

tables. Figure 16 on page 38 is an example of the tables.

For the D7212GV2, Points 9 to 40 can use

either D8127 or D9127 POPITs.

9.3.7 Program Record Sheet

The first column of the table in Figure 16 on page 38

contains the POPIT Switch Settings for the D8127

POPITs. On the D8127 POPITs, the switches are

numbered 1 to 6, from left to right. 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 D7212GV2 Program Entry Guide

(P/N: F01U003804) 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 D7212GV2 Program Entry

Guide (P/N: F01U003804) 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 D7212GV2

Program Entry Guide (P/N: F01U003804)

The seventh column shows the BFSK/Relay report

code, which is the point number reported for this point

when the control panel is using the BFSK format.

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.
