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 D9412GV3; up to 67 POPITs for the D7412GV3 (Figure 16 on page 38 and Figure 17 on page 39).

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. 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 39.

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 D9412GV3/D7412GV3 Program Record Sheet (P/N: F01U170809). The program record sheet provides information about the Point Assignments tables. Figure 18 on page 42 is an example of the tables.

9.3.7Program Record Sheet

The first column of the table in Figure 18 on page 42 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 D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807) 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 D9412GV3/D7412GV3 Program Entry Guide (P/N: F01U170807) 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 D9412GV3/D7412GV3 Program Entry Guide

(P/N: F01U170807).

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 IIIa2 format.
