4.3. RM-300MF Fireman’s Microphone
This microphone is designed to be used exclusively for emergency broadcasts made by firemen or other
persons when instructing building occupants to evacuate in emergency situations. It can activate the
emergency mode, start and stop automatic broadcasts of emergency announcements, reset emergency
signals, and make live microphone announcements in emergency situations. Operating the microphone’s CPU
OFF switch allows all-zone calls (simultaneous attenuator-free global calls) to go through. No general
broadcasts can be made. By connecting the RM-320F Fireman’s Microphone Extension to the RM-300MF
Fireman’s Microphone, the zone selection or failure indication/failure acknowledgment/failure reset* function
can be enabled. Up to 3 RM-320Fs can be connected to the Fireman’s Microphone, expanding the available
keys up to 20 per unit.
* This function can be used only when all the versions of VM-3000VA firmware, VM-3000E firmware, and VM-
3000 Setting Software are 2.00 or later.
