No.2 fire alarm control panel to the No.20 fire alarm control panel) will execute the
corresponding operation; and if the said key on an zone fire alarm control panel is
pressed, only the state of the zone fire alarm control panel will be changed. If the
RESET key on the concentrator is pressed by an operator when an zone fire alarm
control panel in the networked system is in the set state, the zone fire alarm control
panel will immediately respond to the restoration command and the file is set by it at
that time will lose the content updated this time, namely the data newly set after the
last time saving will not be saved automatically. Therefore, when the networked
system is debugged by several debugging personnel at the same time, it is
necessary to disconnect the networking cables of the set fire alarm control panel
temporarily before inputting mass data.
