3.0 Installation
Before installing the D8128D OctoPOPIT, become familiar with the operation and installation guide and the
program entry guide corresponding to your system. Follow the four-step process for the most effective
installation:
•Set the OctoPOPIT switches.
•Mount the OctoPOPIT to the enclosure.
•Wire the OctoPOPIT.
•Wire the OctoPOPIT sensor loops.
3.1 Setting OctoPOPIT Switches
The D8128D has two sets of DIP switches. Use the DIP switches on
the top of the unit (with the terminal strip along the left edge) to
set the OctoPOPIT address. Use the DIP switches at the bottom of
the unit to enable or disable individual points connected to the
OctoPOPIT.
3.1.1 Address Switches
The switches on the D8128D OctoPOPIT set point assignments and
line termination (Figure 1). These switches are easier to set before
mounting the D8128D in the enclosure.
3.1.1.1 Address Assignment Switches
Switches 1, 2, 3, and 4 assign the OctoPOPIT sensor loops to point
numbers on the control panel. Table 6 on page 11 show the
OctoPOPIT switch settings for point assignments, depending on
the control panel being used. 23451678

•If no D8125 POPEX is connected to ZONEX 1, set switch 5 of only one D8128D connected to those
terminals to the ON position.

D8128D
D8128D Installation Guide
F01U070537-07 Page 7 © 2015 Bosch Security Systems, Inc.
•If a D8125 POPEX is connected to ZONEX 1, set switch 5 of all D8128Ds connected to those
terminals to the OFF position.
•If no D8125 POPEX is connected to ZONEX 2, set switch 5 of only one D8128D connected to those
terminals to the ON position.
•If a D8125 POPEX is connected to ZONEX 2, set switch 5 of all D8128Ds connected to those
terminals to the OFF position.
3.1.2 Point DIP Switches
Each point connected to the D8128D is enabled or disabled by turning its respective DIP switch to the closed or
open position, respectively. For example, to disable a device connected to Terminal P3 (Point 3), move DIP
Switch 3 to the OPEN position.
Use the point DIP switches to disable conflicting points, such as when a D9210B Access Control Module must
be assigned to a point within the range of the D8128D OctoPOPIT. In this example, a D9210B is assigned to
Point 20. On the same system, a D8128D OctoPOPIT is assigned to Points 17 through 24. Moving the DIP switch
for Point 4 to the OFF position effectively disables Point 20, allowing normal operation of the D9210B and the
OctoPOPIT.
Terminate each OctoPOPIT sensor loop with a 1 kΩEOL resistor. Attach a resistor even if you do not enable the
loop.
3.2 Mounting the D8128D
You can install the D8128D in the enclosure with the control panel using standard four-conductor 22 AWG (0.8
mm) wire or in a separate enclosure (such as D8103, D8108A, or D8109) up to 200 ft (61 m) from the control
panel. Use the recommended shielded standard four-conductor 22 AWG (0.8 mm) wire. Refer to the cabling
specifications in Table 2 on page 4 when using the D125B or the D129.
For UL Listed systems, mount the D8128D in a tamper-proof enclosure.
To install the D8128D in the control
panel enclosure:
1. Align the D8128D with any of
the four mounting locations in
the enclosure (Figure 2).
2. Secure the module to the
enclosure using the supplied
screws.
Use the D137 Mounting Bracket to
install D8128D Modules in enclosures
with no module-mounting locations
available.

3.3.2 Wiring Multiple D8128D Modules to the Control Panel using Molex Connectors
Each D8128D includes a 12-in. (30 cm) female-to-female Molex cable assembly.
P1 and P2 are Molex connectors that parallel the COM, IN, OUT and +12 VDC terminals on the terminal strip. In
installations using multiple D8128D Modules, use these connectors (as opposed to terminals) with the supplied
cable. When connecting D8128D Modules directly to the control panel, use the terminal strip.
The supplied Molex connectors are keyed. A Molex plug can only fit in one direction. Ensure the connector is
correctly attached, the red wire is on the bottom of P1 (or P2), and the black wire is on the top.
When connecting multiple D8128D Modules to a control panel, connect the control panel terminals to P1 or the
Com, In, Out, and +12 V Terminals on the first D8128D. Then connect P2 of the first D8128D to P1 of the
second D8128D and so on. Refer to Figure 4.

3.4 Wiring OctoPOPIT Sensor Loops
3.4.1 OctoPOPIT Sensor Loops
Only the resistance on the loop limits the number of normally open (NO) and/or normally closed (NC) detection
devices each sensor loop can supervise. Resistance on each sensor loop must be less than 100 Ω with the
detection devices connected.
The OctoPOPIT detects open, short, normal, and grounded circuit conditions on its sensor loops and transmits
the conditions to the control panel. Each sensor loop is assigned a point number and transmits to the control
panel separately. 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.

The OctoPOPIT has two rows of terminal numbers. 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 EOL resistor.
Attach a resistor even if you do not enable the loop. The OctoPOPIT includes a D105BL resistor for each sensor
loop.
Do not duplicate point assignments. Points do not function properly if assigned to both an OctoPOPIT sensor
loop and a POPIT, to two OctoPOPIT sensor loops, or to two POPITs.
