1.0 Introduction
This guide covers installation of the D8125 POPEX Module for use with the D9127U/T POPITs on the new
G Series control panels (B9512G, B9512G-E, B8512G, B8512G-E), G Series control panels (D9412GV4,
D7412GV4, D7212GV4, D9412GV3, D7412GV3, D7212GV3, D9412GV2, D7412GV2, D7212GV2, D9412G,
D7412G, D7212G), and D9124 control panel.
The B600 Retrofit (ZONEX) module is
required to use the D8125 on the
B9512G, B9512G-E, B8512G, and
B8512G-E control panels.
Refer to the installation and programming literature for the control panel for a detailed description of the
