FS-8700-45 – Grinnell TFX Minerva

FieldServer Driver – Serial


Grinnell TFX Minerva



The Grinnell TFX Minerva driver allows the FieldServer to transfer data from a TFX Fire Alarm System.  The FieldServer connects using RS-232 to a TLT-530 with its Third Party Interface protocol. An RS-232 connection must be dedicated to the Grinnell Interface for each TLT-530 interface used (one per separate fire system).  Using the Grinnell TFX Driver, the FieldServer should be considered a Server, allowing other clients to read states of other panels as well as generate events to the Grinnell system.
