The NOTIFIER FTM-1 (Firephone Telephone Module) is an intelligent addressable firephone control module designed for FlashScan SLC loops in ONYX panels like NFS2-640 and NFS2-3030.
It monitors and controls up to two firefighter handsets per module, connecting remote phones to a central console with supervision for normal, off-hook, and trouble states, plus ringing until connected.
