General Description
The MMF-300 Monitor Module is intended for use in addressable, two-wire systems, where the individual address of each module is se-

contact fire alarm or supervisory devices. The module has a panel controlled LED indicator. The MMF-300 can be used to replace an
M300 module in existing systems.
