Installing The Octopopit; Wiring Octopopits; Line Termination - Radionics D9412G Operation And Installation Manual

Connect the zone outputs on the D125B or D129 to the OctoPOPIT sensor loop inputs. The D125B or D129 and
the OctoPOPIT must be mounted in the enclosure with the panel or in a separate enclosure connected to the
panel's enclosure by conduit not more than 20 ft. (6 m) in length.
8.4.3

Installing the OctoPOPIT

You can install the D8128D OctoPOPIT Module in the enclosure with the panel, or in a separate enclosure (model
D8103, D8108A, or D8109) up to 200 ft. (61 m) from the panel using standard four-conductor 22 AWG (0.8 mm)
wire. If you mount the OctoPOPIT in a separate enclosure, use shielded cable to avoid electro-magnetic
interference. See EMI on Long Wire Runs in the D9412G/D7412G Installation and Troubleshooting Quick
Reference Guide .
Tampered enclosures for UL certificated systems: The D125B or D129 and the OctoPOPIT must be mounted in
the enclosure with the panel or in a separate enclosure connected to the panel's enclosure by conduit not more
than 20 ft. (6 m) in length.
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 and section 8.4.7 Address Assignment Switches.
2. Align the OctoPOPIT Module with any of the four mounting locations in the enclosure. See Figure 2 .
3. Use the screws provided with the module to secure it in the enclosure.
Use the D137 Mounting Bracket to install OctoPOPITs in enclosures with no module mounting locations available.

Wiring OctoPOPITs

Follow the procedure below to wire D8128D OctoPOPIT Modules to the D9412G/D7412G. 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 23 on the D9412G (Terminal 9 on the D7412G).
3. Connect Terminal 2 on the OctoPOPIT to Terminal 28 on the panel if assigning point numbers from 9 to 127
(or 9 to 75 if using a D7412G) to this OctoPOPIT. See section 8.4.7 Address Assignment Switches.
If assigning point numbers from 129 to 247, connect Terminal 2 on the OctoPOPIT to Terminal 26 on the
D9412G.
4. Connect Terminal 3 on the OctoPOPIT to Terminal 27 on the D9412G if assigning point numbers from 9 to
127 (or 9 to 75 if using a D7412G) to this OctoPOPIT.
If assigning point numbers from 129 to 247, connect Terminal 3 on the OctoPOPIT to Terminal 25 on the
D9412G.
5. Connect Terminal 4 on the OctoPOPIT to Terminal 24 on the D9412G (Terminal 3 on the D7412G).
See section 8.4.6 OctoPOPIT Sensor Loops for instructions on connecting devices to the OctoPOPIT's sensor

loops.
8.4.5

Line 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.
· If there is a D8125 POPEX module connected to ZONEX 1, set switch 5 of all D8128Ds connected to those
terminals to the OFF position.
· If there is no D8125 POPEX module connected to ZONEX 2, set switch 5 of only one D8128D connected to those
terminals to the ON position.
· If there is a D8125 POPEX module connected to ZONEX 2, set switch 5 of all D8128Ds connected to those
terminals to the OFF position.
See Figure 14a and Figure 14b for the location of the switches on the OctoPOPIT.
