Operation of the Control Panel Overview
22 IFC-3030 Operations Manual — PN 52026:C 08/05/2005
soft keys displayed on the screen is ACKNOWLEDGE. Use this key to respond to new alarm or
trouble signals. When this key is pressed, the control panel does the following:
• It silences the piezo sounder on the panel if it is enabled
• It transfers the event to the history buffer
• If the panel is networked, it will send a network message.
There are two types of acknowledge; point and block. Point acknowledge is for fire alarms: fire
alarms are acknowledged one at a time when the Acknowledge soft key is pressed. Block
acknowledge is for all other types of off-normal events: these events are acknowledged all at the
same time, with a single stroke to the Acknowledge soft key.
Note: If Local Control is disabled, acknowledgements can not be made by pressing the
ACKNOWLEDGE soft key on the panel display. Events must be acknowledged from a
preprogrammed remote location. When DCC (Display and Control Center) participation is enabled,
panel acknowledgement can be performed when it is the DCC. When it is not, permission must be
granted from the DCC before the panel can make an acknowledgement. Pressing the
ACKNOWLEDGE soft key will automatically request permission from the DCC.
Note: If the panel is programmed for Receive Mode, events and the clearing of events must be
handled one at a time: each event must be acknowledged, and each clear (whether the clear occurs
automatically or as the result of a panel reset) must be acknowledged.
