Installing The D8125 Popex Module; Wiring The D8125 To The D9412/D9112; Wiring Popits To The Data Expansion Loop; D9000/D7000 Series Operation & Installation Manual - Radionics D9000 Series Operation And Installation Manual

Installing the D8125 POPEX Module

Save the POPIT Label Sheets: The D8125 is
packaged with two sets of POPIT label sheets.
One is marked for use with the D9412/D9112 .
Save this set. You will use it later to label the
POPITs.
Mounting
Follow the procedure below to install the D8125
in the enclosure with the panel.
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.

Wiring the D8125 to the D9412/D9112

Follow the procedure below to wire one or two
D8125 modules to the panel.
See Figure 12.
Power down first: Power down the panel by
disconnecting the positive (red) battery lead at
the battery and unplugging the transformer.
Warning, reversed polarity damages the
D8125: Make sure you correctly wire the D8125
AUX and GND terminals to the panel.
For points 9 to 127 (9 to 75 on D7412/D7212):
1. Connect the GND terminal of the D8125 to
terminal 23 on the D9412/D9112. Connect
the GND terminal of the to terminal 9 on the
D7412/D7212.
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 D9412/D9112. Connect
the AUX terminal to terminal 3 on the D7412/
D7212.
For point numbers from 129 to 247 (D9412/
D9112 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.
Do not connect more than one D8125 to ZONEX
1, terminals 27 and 28, or ZONEX 2 (D9412/
D9112 only), terminals 25 and 26.
See Wiring POPITs to the D8125 for instructions
on connecting POPITs to the D8125 POPEX
module.

Wiring POPITs to the Data Expansion Loop

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. See POPIT Module Point
Assignments.
Review Premises Wiring in the Installation
section of this manual to determine if shielded
wire is required. Determine the required wire
gauge for each data expansion loop using Table
2.

Table 2: Data Expansion Loop Wire Specifications
Combine data expansion loops: The maximum
lengths shown in Table 1 are for all data
expansion loops connected to the same POPEX
module combined.
Before installing the POPITs, make sure the
resistance on the data expansion loop is no more
than 60Ω.
Wiring POPITs together: Do NOT connect
POPITs to each other in series, or with a T-tap.
Doing so may cause random missing POPIT
conditions. Follow the
procedure below to connect POPITs to one
another
in parallel. Figure 12 shows a typical
configuration.
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. You don't need 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 three
inches apart to prevent the tamper magnets from
interfering with each other.
