Off-board Points
8.4.6
OctoPOPIT 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 ohms 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, closed, normal, and grounded circuit conditions on its sensor loops and
transmits the conditions to the panel. A ground on the positive leg of the sensor loop transmits a shorted condition
for the point. Each sensor loop is assigned a point number and transmits to the panel separately.
Radionics 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 k
Ω
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.
8.4.7
Address Assignment Switches
Switches 1, 2, 3, and 4 assign the OctoPOPIT sensor loops to point numbers on the panel.
Table 9 shows the
OctoPOPIT switch settings for point assignments.
Table 9: D8128D OctoPOPIT Switch Settings for D9412G/D7412G
Note:
For the D8128D OctoPOPITs assigned to Points 121-127 and 241-247, be sure to set Point Input Switch 8 to the
OPEN position.
Dipswitch 4 is not used for setting addresses. See section 8.4.5 Line Termination for further instructions.
D9412G uses Points 9-127 on ZONEX 1 and Points 129-247 on ZONEX 2.
D7412G uses Points 9-75 on ZONEX 1 only.
8.5
Testing Off-board Points
Use the Service Walk Test to test off-board points. See the
D9412G/D7412G Installation and Troubleshooting
Quick Reference Guide for instructions. Test to be sure that all off-board points operate properly.
Walk test does not show extra points: Only the Service Walk Test shows extra points. If the point assignment
switches on a POPIT or OctoPOPIT are set incorrectly, it may create both missing and extra points. If the same
point number is assigned to two or more POPITs or OctoPOPITs, none of the points with that number will test
correctly.
