Off-board Points

Mounting

Follow the procedure below to install OctoPOPITs in the enclosure.

1.It is easier to set the switches on the D8128D before mounting it in the enclosure. See Section 8.4.5 Line Termination below and Section 8.4.7 Address Assignment Switches on page 44.

2.Align the OctoPOPIT Module with any of the four mounting locations in the enclosure. See Figure 2 on page 21.

3.Use the screws provided with the module to secure it in the enclosure.

4.Use the D137 Mounting Bracket to install OctoPOPITs in enclosures with no module mounting locations available.

8.4.4Wiring OctoPOPITs

Follow the procedure below to wire D8128D OctoPOPIT Modules to the D7212G. Both OctoPOPIT and POPEX Modules can be connected to the same Point Bus terminals. The modules wire in parallel. Remember, never assign the same point number to more than one point.

1.Power down first: Power down the panel by disconnecting the positive (red) battery lead at the battery and unplugging the transformer.

2.Connect Terminal 1 on the OctoPOPIT to Terminal 9 on the D7212G.

3.Connect Terminal 2 on the OctoPOPIT to Terminal 28 on the panel if assigning point numbers from 9 to 40 to this OctoPOPIT. See Section 8.4.7 Address Assignment Switches on page 44.

4.Connect Terminal 3 on the OctoPOPIT to Terminal 27 on the D7212G.

5.Connect Terminal 4 on the OctoPOPIT to Terminal 3 on the D7212G.

6.See Section 8.4.6 OctoPOPIT Sensor Loops on page 44 for instructions on connecting devices to the OctoPOPIT’s sensor loops.

8.4.5Line Termination

Switch 5 sets line termination.

If there is:

·No D8125 POPEX module connected to ZONEX 1, set switch 5 of only one D8128D connected to those terminals to the ON position.

·A D8125 POPEX module connected to ZONEX 1, set switch 5 of all D8128Ds connected to those terminals to the OFF position.

See Figure 15 on page 45 for the location of the switches on the OctoPOPIT.
