GENERAL DESCRIPTION
The RM-300MF Fireman's Microphone is designed for exclusive use with the VM-3000 Series. It is
equipped with an emergency activation key, permitting pre-recorded evacuation and alert announce-
ments to be activated, and microphone announcement to be made in emergency situations. By connect-
ing the RM-320F Fireman's Microphone Extension to the RM-300MF, the number of function keys can be
expanded. The zone selection or failure acknowledgment function can be assigned to such function
keys.

NOTE ON REPAIR WORK SAFETY SPECIFICATIONS2 2
RM-300MF
NOTE ON REPAIR WORK SAFETY
Follow the instructions below, both to prevent accidents when making repairs and to ensure post-repair
product safety.
Do not apply voltages other than those specified for the equipment or its compo-
nents.
Applying voltages other than the rated voltage could cause electrical breakdown or over-current, possi-
bly resulting in electric shock or fire. Power is supplied from the VM-3000 System.
After replacing parts, be sure to return the new parts and any other affected parts
to their previous configuration.
Check that all screws, parts, and wiring removed or changed during servicing have been restored to
their original states. Also, confirm that no damage has occurred around the serviced area.
Do not modify the design of circuit boards or other electronic elements.
Modifying circuit boards could cause electric shock or result in a fire hazard due to excessive heat
build-up. User modification automatically exempts the manufacturer from all personal and property lia-
bility caused by such modification, and the user who carried out such modification shall be solely
responsible for such accidents.
Since lead can become an environmental contaminant, this unit has been manufactured using solders
that contain no lead in the printed circuit board.
[While conventional solders are alloys of zinc and lead, lead-free solder is comprisend of an alterna-
tive alloy that contains no lead.]
NOTES
• Circuit boards using lead-free solder bear a lead-free solder designation. To maintain the integrity
of this designation, be sure to use lead-free solder when repairing such lead-free solder circuit
boards. Boards not marked with the lead-free solder designation may legally be serviced using
conventional solders.
• Because the melting point of lead-free solder (approximately 220°C) is 30°C-40°C higher than that
of conventional (lead-zinc alloy) solder, it tasks little longer to melt. It is recommended that a sol-
dering iron with controllable temperature be used and set to 20°C higher than would normally be
used with conventional solder.
Identifying printed circuit boards that use free-lead solder
Printed circuit boards that use lead-free solder have the following designation printed or stamped on
either side of the board.

This microphone is designed to be used exclusively for emergency broadcasts made by firemen or other per-
sons 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 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.
1. Power Indicator (green)
Lights when power is supplied to the unit.
2. Emergency Activation Switch / Emergency
Indicator (red)
Places the system in emergency mode while
illuminated. Also flashes when the emergency
mode is activated by external equipment. In this
event, if the switch is pressed to acknowledge
the emergency activation, it changes from flash-
ing to steady ON mode.
3. Buzzer
Sounds when a failure is detected or when the
emergency mode is activated.
* The buzzer sounds with the same tone in
either case.
4. Buzzer Volume Control [SP]
Adjusts the volume of the buzzer (3).
5. Microphone Volume Control [MIC]
Adjusts the volume of the emergency micro-
phone (20).
6. Microphone Holder
Holder for the emergency microphone (20).
7. CPU ON/OFF Switch [CPU]
Turns the CPU on and off. Normally set to the
ON position. Turning this switch off allows all-
zone calls by the CPU OFF function. To use the
CPU OFF function, Switch 8 of the DIP switch
(22) on the bottom surface must be set to ON.
8. Indication Label Holder
Write the name, purpose, etc. of the indicator
and key on a label and insert the label into the
holder from the top. Labels can be printed using
the setting software. (For more information, refer
to "Printing Remote Microphone Labels" in the
separate software manual.)
9.
Communication Failure Indicator (yellow/green)
Flashing Yellow
Indicates that a failure has been detected in
communications with the VM-3240VA and VM-
3360VA.
Lit Green
Indicates that the unit is in maintenance mode*.
In this event, the unit does not work. To return to
normal condition, set Switch 1 of the DIP switch
(22) on the bottom surface to OFF.
* Unit is placed in this mode if Switch 1 of DIP
switch (22) on the bottom surface is set to ON.
10. CPU OFF Indicator (red)
Lights when the unit is placed in CPU OFF
mode using the CPU OFF switch.
11. RM Reset Key
Resets the unit.
12. Evacuation Announcement Indicator (red)
Lights when Evacuation announcements are
made.
13. Evacuation Announcement Start Key
Plays the Evacuation announcement when in
emergency mode. When the RM-320F Fireman’s
Microphone Extension is used, the announce-
ment is broadcast over the zone(s) selected by
the RM-320F. Pressing this key without first
selecting the zones automatically makes an all-
zone call. To stop the Evacuation announcement,
hold down the key for 3 seconds.
14. Alert Announcement Indicator (red)
Lights when an Alert announcement is made.
15.
Alert Announcement Start Key / Lamp Test
Key
Plays the Alert announcement when in emer-
gency mode. When the RM-320F Fireman’s
Microphone Extension Unit is used, the
announcement is broadcast over the zone(s)
selected by the RM-320F. Pressing this key with-
out first selecting the zones automatically makes
an all-zone call. To stop the Alert announcement,
hold down this key for 3 seconds. Pressing this
key during general broadcast mode allows a lamp
test to be conducted.
16. Emergency Reset In-Progress Indicator (red)
Remains lit while the Emergency Reset key (17)
is pressed.
17. Emergency Reset Key
Terminates emergency broadcasts to return to
general broadcasts.
18. Emergency Microphone In-Use Indicator
(green)
Lights when the Emergency Microphone (20) is
used for broadcasts.

NOMENCLATURE AND FUNCTIONS4 4
RM-300MF
19. External Emergency Equipment In-Use
Indicator (orange / green)
Flashes when external emergency equipment is
used for broadcasts.
Orange: Indicates the mode that disables broad-
casts from the unit.
Green: Indicates the mode that allows the unit to
interrupt broadcasts from external equipment.
20. Emergency Microphone
After the emergency mode is activated, press
the Talk key located on the side of the micro-
phone to make an all-zone call or emergency
broadcast over the selected zones (the RM-
320F is required for zone selection).
21. RM-320F Connector
Connect the RM-320F Fireman’s Microphone
Extension Unit to this connector.
22. DIP Switch
Used to set the unit ID number and equipment
functions.
Switch 1 [MAINTENANCE]
Always set this switch to the OFF position.
Default setting: OFF
Note
If this switch is set to ON, the unit is placed in
the maintenance mode and the front panel-
mounted Communication Failure indicator (9)
lights green, causing the unit not to work.
Switches 2 – 4
Not used.
Default setting: OFF
Switch 5 [UNIT ID]
Sets the ID number of the Fireman’s
Microphone.
Default setting: ON
Switch 6 [COMPRESSION]
