2-28 Operating 15088: K 3/21/01
Section 5.5A Acknowledging Troubles in Receiving Unit Mode
(Block Acknowledge Disabled)
The receiving unit mode of operation is required for all NFPA proprietary supervising station and central station
receiving units.
To acknowledge a device, zone, system or annunciator module trouble condition:
ACK
STEP
Push
and the TROUBL status will change to
ACK TB
(Acknowledged Trouble).
When the trouble condition clears, the panel will display CLR TB and the piezo will sound again. To
acknowledge the clearing of a trouble condition:
Push
ACK
STEP
and the CLR TB status will change to
ACL TB
(Acknowledged Clear Trouble).
When multiple events have occurred, the AM2020/AFP1010 will display the first event that occurred (with the
exception that the first fire alarm will always override any previous trouble). When the ACK STEP key is
pushed, the operator will have acknowledged the highest priority event,
not necessarily the event that is being
displayed
on the CRT Monitor and DIA. The acknowledged message for the first prioritized event will be
displayed for several seconds, followed by display of the next priority unacknowledged event.
NOTE
The piezo sounder will be silenced only after all events have been acknowledged.
Section 5.6 Displaying Current Alarms and Troubles
To display alarms and troubles that have been acknowledged but not cleared:
Push and the next event in AM2020/AFP1010
memory will be displayed on the LCD. All
events in memory can be reviewed by repeated
depression of the
ACK STEP
key.
