POPIT Sensor Loops

The number of normally-open and/or normally-closed detection devices each sensor loop can supervise is limited only by
the resistance on the loop. 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.
POPITs detect open, shorted, normal, and grounded circuit conditions on their sensor loops. They transmit the condition of
their loops to the D9112B1/D7212B1. A ground on the sensor loop reports as an open condition. Each POPIT is
programmed and transmits to the D9112B1/D7212B1 separately.
Terminate each POPIT sensor loop with the 33 kΩ end-of-line resistor (Bosch Security Systems D106F) included with each
POPIT.
Bosch Security Systems recommends you use twisted-pair wire in all POPEX/POPIT installations for both the data
expansion loop wiring and the POPIT sensor loops. Run wires away from AC sources to prevent AC induction. If you
suspect a noisy environment, use shielded cable.

POPIT Module Point Assignments

Six switches on each POPIT assign the module to a point number. POPIT switch settings are found in the Point Assignment
section of the D9112B Program Record Sheet (P/N: 74-06100-000). Refer to Figure 7.
3.2.6.1

D9112B Program Record Sheet

The first column on the program record sheet contains the switch settings for the POPITs. Switches are numbered 0 to 6, left
to right. Set switches whose number appears in the setting to the ON position. Set switches with a dash (-) in the switch
position in the setting to the OFF position. See Figure 7.
The second column contains the translation of the point number into the D8112 ZONEX format. See Point User Flag in the
Panel Wide Parameters module of the D9412G/D7412G Program Entry Guide (P/N: 47775) for an explanation of this feature.
The third column contains the point number as it is displayed at command centers. The fourth column contains the point
index. See the Point Index Parameters module in the D9412G/D7412G Program Entry Guide (P/N: 47775) for an explanation
of the point index.
The fifth column shows the area the point is assigned to. The sixth column shows the Debounce Count for the point. See
Debounce Count in the Point Assignments module in the D9412G/D7412G Program Entry Guide (P/N: 47775).
The seventh columns shows the BFSK report code. It is the point number reported for this point when the panel is using the
BFSK format. The eighth column contains the text displayed at command centers for the point. The text is transmitted to the
receiver when the panel is using the Modem II format.
3.2.6.2

POPIT Labels

Off-board points are numbered 9 to 71 (9 to 48 for D7212B1) and 73 to 135. The D9112B1 reserves Points 72 and 136 for
internal use. You must connect POPITs for Points 73 to 135 to expansion loops connected to POPEX #2.
Four sheets of peel-off POPIT labels are supplied with the D8125 POPEX module.
To place the POPIT Labels in using a 9000 Series Control Panel, use the sheet marked POPIT Labels -- D9412, either Bank One
(Points 9-128) or Bank Two (Points 129-248) depending on the points used, and refer to Figure 8.
