8.4.6OctoPOPIT Sensor Loops

Only the resistance on the loop limits the number of normally-open and/or normally-closed detection devices each sensor loop can supervise. Resistance on each sensor loop must be less than 100 Ω with the detection devices connected.

Certain UL and NFPA applications may limit the number of detection devices. Consult the appropriate UL or NFPA standards.

The OctoPOPIT detects open, short, normal, and grounded circuit conditions on its sensor loops and transmits the conditions to the panel. Each sensor loop is assigned a point number and transmits to the panel separately.

Bosch Security Systems recommends you use twisted-pair wire for the OctoPOPIT sensor loops to avoid EMI problems. Run wires away from the premises telephone and AC wiring. If you suspect a noisy environment, use shielded cable.

There are two rows of terminal numbers on the OctoPOPIT. In the row closest to the terminal blocks, the positive outputs for the sensor loops are labeled P1 to P8. Sensor loop outputs P1 and P2, P3 and P4, P5 and P6, and P7 and P8 share common terminals. The common terminals for each pair are labeled COM.

Terminate each OctoPOPIT sensor loop with a 1 kΩ end-of-line resistor. Attach a resistor even if you don’t enable the loop. The OctoPOPIT comes with a D105BL resistor for each sensor loop.

Take care not to duplicate point assignments. Points assigned to both an OctoPOPIT sensor loop and a POPIT, two OctoPOPIT sensor loops, or two POPITs do not function properly.

8.4.7Address Assignment Switches

Switches 1, 2, 3, and 4 assign the OctoPOPIT sensor loops to point numbers on the panel. Table 10 shows the OctoPOPIT switch settings for point assignments.

8.5Testing Off-board Points

Use the Service Walk Test to test off-board points. See the D9412G/D7412G/D7212G Installation and Troubleshooting Quick Reference Guide (P/N: 43700) for instructions. Test to be sure that all off-board points operate properly.

Walk test does not show extra points: If the point assignment switches on a POPIT or OctoPOPIT are set incorrectly, it may create both missing and extra point conditions. If the same point number is assigned to two or more POPITs or OctoPOPITs, none of the points with that number will test correctly. Refer to Section 8.1 Point (ZONEX) Bus D7212G Terminals 27 to 28 on page 37 for additional infomation on how to troubleshoot POPITs or extra point conditions.
