the MANUAL key on any other fire alarm control panel is pressed, only the manual control state of
the fire alarm control panel will be changed. The manual control state will be saved upon a power
failure. In other words, if the system suffers a power failure and is then powered on again, the
manual control state before the power failure will be restored.
5) LOCAL MUTE function key
Pressing the LOCAL MUTE key can mute the alarm sounds given by the buzzer and fire display
panel in the fire alarm control panel and the graphical display device in the fire control room. Upon
a new alarm under the mute state, the buzzer and other audible alarm devices will be restarted.
The LOCAL MUTE key is the only key not under the password protection in the system and it can
be operated no matter whether the keyboard panel is opened or closed.
6) OUTSIDE MUTE function key (with a light)
Pressing the OUTSIDE MUTE key can mute the alarm sounds of external equipment (including
the alarm bell and the audible and visual alarm). If there is a fire alarm, this key can disable or
enable the alarm sounds of corresponding alarm devices. After this key is pressed, the alarm
sounds will be muted and the OUTSIDE MUTE light will be lit. Upon a new fire alarm discovered
in the system when the alarm bell or the audible and visual alarm is linked, the OUTSIDE MUTE
light will go out and the alarm sounds of the corresponding alarm devices will be enabled again.
This key can be operated after the user logs in the system only.
7) ISOLATION function key (with a light)
If the ISOLATION key is pressed, all the bus equipment (it may be any bus equipment in the
networked system) currently under the alarm state (the fire alarm state, the feedback state or the
fault state) will be isolated. If a piece of bus equipment is isolated, the system will not give any
audible/visible alarms for the alarm information of the bus equipment. The fault information of the
interface boards, the power supplies, the printer, the display panels and the communication of the
fire alarm control panel should not be isolated. If any bus equipment in the system is isolated, the
ISOLATION light will be lit.
User’s Tip: Only the superuser is allowed to use this function. Isolation involves
displayed information. The isolated bus equipment can run normally. Only a current
alarm key will be available on the panel in this case. Isolation operations like
ISOLATION QUERY and CANCEL ALL ISOLATIONS may be done through menu
operations.
8) SELF-TEST function key
After the SELF-TEST key is pressed, the system will enter the self-test procedure: All the lights
will be lit for a light inspection; the buzzer will try multiple sound modes (fire alarm, fault,
feedback); and the screen will light the dot matrixes in order. After the self-test, the system will
exit automatically. If the SELF-TEST key is pressed during the self-test, the system will exit the
self-test state.
△
Caution: Under the self-test state, the system will not receive alarm signals.
!
9) RESET function key
After the RESET key is pressed, all the present alarms will be eliminated and the system will
be restarted. The entire process needs about 30s to 60s. If multiple fire alarm control panels are
networked and the RESET key on the No.1 fire alarm control panel in the network is pressed, all
the networked fire alarm control panels will execute the reset operation; and if the RESET key on
any other fire alarm control panel networked is pressed, only the fire alarm control panel will be
reset.
△
Caution: If multiple fire alarm control panels are networked and the No.1 fire alarm
control panel is the concentrator (the system’s principal fire alarm control panel), then,
when the RESET key, the ISOLATION key, the LOCAL MUTE key, the OUTSIDE
MUTE key, the INTEGRATION key, the SOUNDER key or the MANUAL key on the
concentrator is pressed, all the other zone fire alarm control panels networked (the
