3.2.1
Mounting
Follow the procedures below to install the D8125 in the enclosure with the D9112B1/D7212B1.
1.
Align the D8125 POPEX module with any of the four mounting locations in the enclosure. See Figure 2.
2.
Use the screws provided with the module to secure it in the enclosure.
3.2.2
Wiring the D8125 to the D9112B1/D7212B1
Follow the procedures below to wire one or two D8125 modules. Refer to
Figure 4.
WARNING
Remove all power (AC and Battery) before making any
connections. Failure to do so may result in personal injury
and/or equipment damage.
3.2.2.1
Disconnecting the Battery and Transformer
1.
Disconnect the battery by unhooking the positive (red)
battery lead from the battery.
2.
Unplug the transformer.
WARNING
Reversed polarity damages the D8125. Make sure you
correctly wire the D8125 AUX and GND terminals to the
control panel.
3.2.2.2
Wiring Procedure
For Points 9 to 71 (or 9 to 48 for the D7212B1):
1.
Connect the GND terminal of the D8125 POPEX
module to Terminal 23 on the D9112B1 (use Terminal 9
on the D7212B1).
2.
Connect the OUT terminal of the D8125 to ZONEX IN
1, Terminal 27 on the D9112B1/D7212B1.
3.
Connect the IN terminal of the D8125 to ZONEX OUT
1, Terminal 28 on the D9112B1/D7212B1.
4.
Connect the AUX terminal of the D8125 to Terminal 24 on the D9112B1 (use Terminal 3 on the D7212B1).
For Point 73 to 135 (D9112B1 only):
1.
Connect the GND terminal of the D8125 POPEX module to Terminal 23 on the D9112B1.
2.
Connect the IN terminal of the D8125 to ZONEX OUT 2, Terminal 26.
3.
Connect the OUT terminal of the D8125 to ZONEX IN 2, Terminal 25 on the D9112B1.
4.
Connect the AUX terminal of the D8125 to Terminal 24 on the D9112B1.
Do not connect more than one D8125 to ZONEX 1, Terminals 27 and 28, or ZONEX 2, Terminals 25 and 26.
3.2.3
Wiring POPITs to the Data Expansion Loop
You can connect up to 63 POPITs (40 maximum for a D7212B1) to each D8125 module. Use one 2-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 3.2.6 POPIT Module Point Assignments.
Determine the required wire gauge for each data expansion loop using Table 5.
3.2.3.1
Combine data expansion loops
The maximum lengths shown in Table 5 are for all data expansion loops that are connected to the same POPEX module.
Before installing the POPITs, make sure the resistance on the data expansion loop is no more than 60
Ω
.
