* A model “U” POPIT mounted within a tampered enclosure can be used in place of a model “T” POPIT. The following describe the classification of the Bosch Security Systems modules. Please reference the NFPA 72 for the specific details of IDC, SLC, NAC conditions.
POPITs connect to supervised two-wire data expansion loops run from POPIT to POPIT throughout the premises. Data expansion loops connect to a D8125 Point of Protection Expander (POPEX) Module. POPEX Modules connect to the point bus on the panel, Terminals 23 and 24 for power (3 and 9 on the D7412G), and Terminals 25 and 26 (D9412G only), or 27 and 28 for data.
D8125 POPEX/D8127 and D9127 POPIT Modules D8127 and D9127 POPITs use the D8125 POPEX Module to report to the panel. Each D8125 supports up to 119 POPIT points. Connect two D8125 Modules to the D9412G to bring the combined total number of POPIT and on-board points to 246.
D8125, D8127 and D9127 POPIT Modules D8127 and D9127 POPITs use the D8125 POPEX Module to report to the panel. The D8125 supports up to 32 POPIT points (Points 9 to 20). The panel only annunciates activity for each POPIT, not each detection device connected to the sensor loop.
D8125 POPEX/ D8127 and D9127 POPIT Modules D8127 and D9127 POPITs use the D8125 POPEX module to report to the D9412/D9112. Each D8125 supports up to 119 POPIT points. Connect two D8125 modules to the D9412/D9112 to bring the combined total number of POPIT and on- board points to 246.
Expansion (ZONEX) system. The D8125 POPEX Module is a Point Of Protection EXpander. One or two POPEX Modules can be used to interface zone expansion loops to the D8112G series. Each POPEX Module can monitor up to 63 D8126/D8127 POPIT Modules, and as many as 126 individual POPIT Modules can be monitored in a ZONEX system with two POPEX Modules.
D9412G/D7412G Point Expansion for details regarding Popit installation. You can connect up to four data expansion loops to one D8125 input at the motherboard. Data Loops 1 to 4 connect to the D8125 POPEX 1 input on the motherboard (Terminals 11 through 18). Data Loops 5 to 8 connect to the D8125 POPEX 2 input at the motherboard (Terminals 19 through 26).
Installation D9412G/D7412G/D7212G, D9412/D9112/D7412/D7212 Save the POPIT Label Sheets: The D8125 is packaged with two sets of POPIT label sheets. One is marked for use with the D9412/D9112. Save this set. You will use it later to label the POPITs. 3. 1 . 1...
There are two positive (+) and two negative (-) data expansion loop terminals on each POPEX module. Follow the procedure below to connect the data expansion loops to the D8125 POPEX Module (refer to Figure 3). Remember you can only connect a maximum of 119 POPITs to one D8125 on the D9412/D9112 and 67 for the D7412/D7212.
Wiring POPITs to the Data Expansion Loop You can connect up to 63 POPITs (40 maximum for a D7212B1) to each D8125 module. Use one 2-wire data expansion loop or distribute the POPITs on up to three loops. Setting DIP switches on the POPIT modules assigns them to point numbers.
There are two positive (+) and two negative (-) data expansion loop terminals on each POPEX module. Follow the procedure below to connect the data expansion loops to the D8125 POPEX Module. See Figure 5. Remember, you can only connect a maximum of 63 POPITs (40 for a D7212B1) to one D8125, Connect the positive (+) Data terminal from the first POPIT on the data expansion loop to one of the D8125 module’s positive (+) terminals.
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.
Disconnect the battery by unhooking the positive (red) battery lead from the battery. Unplug the transformer. Reversed polarity damages the D8125. Make Figure 10: D8112G1/G2 POPEX Installation sure you correctly wire the D8125 AUX and GND terminals to the control panel. WARNING 18.104.22.168 Wiring Procedure Connect D8112G1/G2 Terminal 4 to the POPEX GND terminal (see Figure 11).
The zone expansion loop is a two-conductor wire interconnecting all POPIT Modules assigned to a single POPEX (see Figure 11). Up to three zone expansion loops can be connected to one D8125 when using shielded or unshielded cable. The required wire gauge for the zone expansion loop(s) (up to three max.) can be determined using Table 6. When using unshielded cable each zone expansion loop can be up to the distance shown in Table 6.
POPIT module. The maximum length of 22 AWG (0.8 mm) cable used for each sensor loop is determined by voltage drop. Bosch Security Systems recommends the use of twisted-pair wire in all POPEX-POPIT installations. If a noisy or unstable environment is suspected, or if a long sensor loop wire run is used, the cable must be shielded against AC induction.
I.D. code ZN104, “ZN1” indicates that the POPIT is assigned to master zone 100 of the D8112G1/G2 Control Panel, and “04” indicates that the POPIT reports as expansion point #4. D8125 Operation and Installation Guide 74-04247-000-N Page 30...
D6500 receiver. A RESTORAL ZONE D will, however, be sent when the expansion loop itself has restored. A complete list of reports received by the D6500 Receiver can be found in the D6500 Report Directory (P/N: 4998132019). D8125 Operation and Installation Guide 74-04247-000-N Page 34...
Voltage should be 9 to 13 VDC at each POPIT. D8128C OctoPOPIT is installed at Install a D8125 POPEX and D9127 POPITs for Points 121-127 on the last address on the ZONEX ZONEX 1 and for Points 241-247 on ZONEX 2.
D8112G. Certain revision 17.07 D8112G Control/Communicators may not detect POPIT faults even when all programming and wiring has been properly completed. Bosch Security Systems has developed two solutions to this problem: 1). Restore all POPITs to a normal condition (close all doors and windows), and then disable and restart the system.
