The FMM-1 Monitor Module is intended for use in intelligent, two-wire systems, to provide either a 2-wire or 4-wire fault tolerant initiating device circuit (IDC) for normally open contact fire alarm and supervisory devices, or either normally open or normally closed security devices.
The FMM-1 can be used to replace an MMX-I module in existing systems.
To ensure proper operation, this module shall be connected to a compatible Notifier system control panel
