The FPE‐7039 MUX expansion module is designed to enhance the conventional features of the FPD‐7024, D7024 or DS9400 FACPs. 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.
