D8128D Octopopit Eight-Point Expander - Bosch B9512G-E Installation Manual

Control Panels
The B9512G using a D8125 can use point of protection input transponder (POPIT) modules to
provide a maximum of 238 off-board points. The B8512G using a D8125 provides up to 91 off-
board points.
D9127 POPITs use the D8125 POPEX Module to report to the control panel. Each D8125
supports up to 119 POPIT points. Connect two D8125 modules to the B9512G to bring the
total number of POPIT points to 238.

The control panel annunciates activity only for each POPIT, not for each detection device
connected to the sensor loop.
D9127 Module enclosures are made of UL Listed fire resistant material. D9127T Modules
contain tamper switches, while D9127U Modules do not. UL requires D9127T Modules for
certificated installations.
Notice!
The expansion loop can be shared between fire and non-fire devices where the POPIT module
provides data isolation between the input and the expansion loop connections.

D8128D OctoPOPIT and D8125 POPEX Modules in parallel to the B600 ZONEX module
terminals. The control panel supports the following number of modules through the B600:
