CKNOWLEDGE
The function of block acknowledge gives the user the ability to acknowledge multiple trouble conditions with a single
depression of the ACK STEP key. The INA will function as follows:
An INA block acknowledge command is transmitted to every programmed node, including display nodes.
Local INA troubles will also be acknowledged if present.
Upon the initiation of a block acknowledge command, local troubles, including any off-line conditions, will
be acknowledged at all programmed nodes, including display nodes.
Acknowledged messages are not recorded as individual events once the block acknowledge message has
been displayed.
Cleared events will be recorded individually as they occur in the history buffer and on the printer. Cleared
events will not be displayed on the LCD.
Cleared events do not have to be acknowledged.
Signals may come and go without being acknowledged. For this reason, the tracking option in the AM2020/
AFP1010 must not be enabled for security input devices.
Upon completion of block acknowledge, the INA will enter the "display acknowledged events" mode of
operation. Refer to the Displaying Current Alarms and Troubles section within this manual.
The block acknowledge function can be disabled.
Push
to execute block acknowledge. The following message will appear:
NETWORK@BLOCK@ACKNOWLEDGE@INITIATED BY
NODE XXX@@@@@@@@@@@@@@ 04:32P@03/01/00
After a node has completed block acknowledge, a message will be transmitted to the INA. The INA, at that point, will show
XXX to represent the FACP node which completed the block acknowledge. The following message will be displayed for
approximately 1.5 seconds:
BLOCK@ACKNOWLEDGE@@@@COMPLETED BY
NODE XXX@@@@@@@@@@@@@ 04:33P@03/01/00
A separate message will be displayed for every node which completed a block acknowledge.
Note:
When employing
Block Acknowledge operation with the INA, all nodes on the network must be configured for Block Acknowledge to
establish proper network operation.
