9.3.4Wiring Data Expansion Loops to POPEX Modules

Each POPEX Module has two positive (+) and two negative (-) data expansion loop terminals. Up to 119 POPITs can be connected to one D8125 on the D9412GV2; 67 for the D7412GV2 (Figure 12 on page 36 and Figure 13 on page 37.

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.

9.3.5POPIT 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 Ground Fault in the D9412GV2/D7412GV2/D7212GV2 Installation and Troubleshooting Quick Reference Guide

(P/N: F01U003638). Each POPIT is programmed and sends signals to the control panel separately.

Terminate each POPIT sensor loop with the 33 kΩ EOL resistor (D106F) included with each POPIT.

Use a twisted-pair wire (six twists per foot) in all POPEX and POPIT installations for both the data expansion loop wiring and the POPIT sensor loops. Run wires away from AC sources to prevent AC induction. If a noisy environment is suspected, use shielded cable. Refer to Section 9.3 Installing the D8125 POPEX Module on page 38.

9.3.6POPIT 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 D9412GV2/D7412GV2 Program Record Sheet (P/N: F01U003635). The program record sheet provides information about the Point Assignments tables. Figure 14 on page 40 is an example of the tables.

For the D9412GV2, Points 73 to 127 and 193 to 247 must use the D9127 POPITs. Points 9 to 72 and 129 to 192 can use either D8127 or D9127 POPITs.

For the D7412GV2, Points 9 to 72 can use either D8127 or D9127 POPITs; however, D9127 POPITs must be used for Points 73 to 75.

9.3.7Program Record Sheet

The first column of the table in Figure 14 on page 40 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 D9127 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 D9412GV2/D7412GV2 Program Entry Guide (P/N: F01U003636) 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 D9412GV2/D7412GV2 Program Entry Guide (P/N: F01U003636)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 D9412GV2/D7412GV2 Program Entry Guide

(P/N: F01U003636).

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 IIIa2 format.
