INA 15092:I 05/30/01

3.3 BLOCK ACKNOWLEDGE

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.
