8.5 Fire Alarm Stop
(1) Start of fire alarm stop
When the fire alarm stop signal is input, the Fire alarm stop operating
message box is displayed. The system sends stop operation and opera-
tion prohibition commands to all the indoor units and disables operation
from the local remote controllers. It also stops the schedule function.
Man-machine operation is also impossible while this message box is dis-
played. However, when the message box is cleared, operation is enabled.
Note:
- When the personal computer, I/O board, IFU, GateWay, etc. is abnormal or the power is OFF, the fire alarm function may
not operate.
- During fire alarm stop input, Fire Alarm is displayed on the message bar.
(2) End of fire alarm stop
When the fire alarm stop signal is reset, the Fire alarm stop operating message box is cleared. An operation prohibition reset
command is sent to all the indoor units and the operation prohibition status returns to its state before the fire alarm stop oper-
ation. The schedule function is restarted and schedule operation groups return to the status in which they were before the
fire alarm stop operation.
Note:
- The unit operation status does not return to the status before the fire alarm stop operation even if fire alarm stop is
reset. Perform running operation from the local remote controller, by man-machine operation, etc.
