With an Additional D8125 POPEX Module:
• You can use D8125 POPEX 2, data loops 5 to 8 (terminals 19 to 26) on the
motherboard.
• You can install an additional 63 POPITs (points 73 to 135) for a maximum of 126
POPITs in the system.
Connecting the Additional D8125 Module
1. Mount the module to a D138 Mounting Bracket, only using the three screws provided.
2. Mount this assembly in the empty slot next to the other modules on the accessory
module carrier. Use the orientation of the other modules as a guide. See
Figure 2
in
the
Installation
section.
3. Connect the clip-on end of the extra wiring harness to the far right connector (J5) on
the motherboard.
4. Connect the hanging wires to the D8125 module as shown in
Table 5
.
Selecting POPIT Point Assignments
Off-board points are numbered 9 to 71 and 73 to 135. The D9124 System reserves
points 72 and 136 for internal use to supervise the data loops. You must connect
POPITs for points 73 to 135 to expansion loops connected to D8125 POPEX #2.
Addresses for each POPIT assign the module to a point number. POPIT address settings
are found on the
POPIT Labels
and in the
Point Assignment
section of the
D9124
Program Record Training Sheet
(see
Figure 11
).
POPIT Labels
Four sheets of peel-off POPIT labels are supplied with the D9124 System. Use the sheet
marked
Vertical Grid for D8125 POPEX #1
for points 9 to 71
.
Use the sheet marked
Vertical Grid for D8125 POPEX #2
for points 73 to 135
.
Each label has two parts. Place the smaller part, with just the point number on it, on the
POPIT terminal block. Place the larger part with the address settings on the POPIT
cover. Set the addresses and cover the POPIT.
Do not program two POPITs for the same point number. After you program all the points,
perform a Fire Test or a Service Walk Test. See
Testing the System
for instructions. If a
point does not test properly, check the programming for a duplicated address.
