The D7039 Multiplex Expansion Module is designed to enhance the conventional features of the D7024 or FPD-7024 Fire Alarm Control Panel (FACP). The module connects directly to the FACP and results in a total of up to 255 addressable points. The module also increases the number of relay outputs (to 58 on the D7024 control panels and 59 on FPD-7024 control panels). It adds an additional 400 events to the history buffer for a total of 499 non-volatile events. It also allows for up to 100 system users (an addition of 84 PINs from the base system). The module can be programmed remotely from a PC using the RPS Remote Programming Software.
