Monitor volume control
Adjusts the monitor speaker volume. The volume
increases as the volume control is rotated
clockwise.
Note: Emergency announcements are made at
the fixed volume level regardless of the monitor
volume control setting. Therefore, the volume of
the emergency broadcast cannot be adjusted.
Monitor speaker
Monitors each broadcast and provides voice
operation guides for emergency broadcast as well
as warning tones for system malfunctions. While
the PA microphone is in use, the monitor speaker
is disabled to prevent feedback.
Output level meter
Indicates a signal output level. See to it that the
meter indicator stays within the green area during
system operation.
Liquid Crystal Display
Displays emergency broadcast operation guides,
general-purpose broadcasting status, and system
malfunctions.
CPU control on/off switch
Normally, set this switch to the ON position. When
the CPU fails and cannot be controlled, setting
the control switch to the OFF position permits only
the all-zone broadcast to be made from the PA
microphone.
Interlock mode key
Selects either "fire alarm interlock" or "fire alarm
all-zone interlock" mode. Each depression of this
key causes both modes to alternate.
Memo
Warning Announcement is always made
automatically by being activated by a fire detector.
