For information on the Multiplex Bus Interface, refer to the D8125MUX Multiplex

Bus Interface Operation and Installation

Guide (P/N: F01U034973).

Save the POPIT Label Sheets: The D8125 is packaged with two sets of POPIT label sheets. One set is marked “Bank 1” for use with the D7412GV3 and D7212GV3. The other set is marked “Bank 2” for use with the D9412GV3 and D9112. Use the sheets later to label the POPITs. Refer to Section 9.3.6 POPIT Module Point Assignments on page 42.

9.3.1Mounting

To install the D8125 in the enclosure with the control panel:

1.Align the D8125 POPEX Module with any of the four mounting locations in the enclosure (Figure 2 on page 15).

2.Using the screws provided with the module, secure it in the enclosure.

9.3.2Wiring the D8125 to the Control Panel

To wire one or two D8125 Modules to the control panel (Figure 16 on page 38 and Figure 17 on page 39):

Power Down the Control Panel: Disconnect the positive (red) battery lead at the battery and unplug the transformer.

For Points 9 to 127 (9 to 75 on D7412GV3):

1.Connect the GND terminal of the D8125 to Terminal 23 on the D9412GV3 or to Terminal 9 on the D7412GV3.

2.Connect the OUT terminal of the D8125 POPEX Module to ZONEX IN 1, Terminal 27.

3.Connect the IN terminal of the D8125 POPEX Module to ZONEX OUT 1, Terminal 28.

4.Connect the AUX terminal of the D8125 to Terminal 24 on the D9412GV3 or to Terminal 3 on the D7412GV3.

For Points 129 to 247 (D9412GV3 only):

1.Connect the GND terminal of the D8125 to Terminal 23.

2.Connect the OUT terminal of the D8125 POPEX Module to ZONEX IN 2, Terminal 25.

3.Connect the IN terminal of the D8125 POPEX Module to ZONEX OUT 2, Terminal 26.

4.Connect the AUX terminal of the D8125 to Terminal 24.

Refer to Section 9.3.4 Wiring Data Expansion Loops to POPEX Modules on page 41 for instructions on connecting POPITs to the D8125 POPEX Module.

9.3.3Wiring POPITs to the Data Expansion Loop

Use one two-wire data expansion loop or distribute the POPITs on up to three loops. Setting DIP switches on the POPIT Modules assigns them to point numbers. Refer to Section 9.3.6 POPIT Module Point Assignments on page 41.

Review Section 4.6.2 Installing and Wiring Detection Devices on page 17 to determine if shielded wire is required. Refer to Table 13 to determine the wire gauge for the length of each data expansion loop.

Table 13: Data Expansion Loop Wire

Specifications

Maximum Length of All Data Expansion Loops Combined

AWG	Length in Meters (Feet)
22	548 (1800)
20	881 (2890)
18	1402 (4600)
16	2231 (7320)

143551 (11,650)

Combine Data Expansion Loops

The maximum lengths shown in Table 13 are for all data expansion loops connected to the same POPEX Module combined.

Wiring POPITs Together

Do not connect POPITs to each other in series or with a T-tap. Doing so might cause random missing POPIT conditions.

Before installing the POPITs, ensure that the resistance on the data expansion loop is no more than 40 Ω.

To connect POPITs to one another in parallel:

1.Connect the positive (+) data terminal from one POPIT to the positive (+) data terminal on the next POPIT.

2.Connect the negative (-) data terminal from one POPIT to the negative (-) data terminal on the next POPIT.

3.Repeat Steps 1 and 2 to connect all POPITs to the expansion loop. It is not necessary to wire the POPITs in any particular order on the loop. The switch setting on each POPIT assigns it a point number, regardless of its physical location.

Three-inch Clearance for Tampered POPITs

Mount tampered POPIT modules at least 7.6 cm (3 in.) apart to prevent the tamper magnets from interfering with each other.
