All parts of the system are switched on, operational and programmed. The live
image can be seen on the monitor. The green and red LEDs are lit. An operating
mode has been programmed.
Operating mode
Automatic acknowledgement, live image on alarm
If an alarm has occurred, the live image is shown with overlaid masks. The
alarm is automatically acknowledged. If a subsequent alarm is detected, the
previous alarm images are deleted. The alarm memory always contains the
newest alarm.
Manual acknowledgement, live image on alarm
If an alarm has occurred, the live image is shown with overlaid masks. The
system remains armed. A subsequent alarm does not store new alarm images,
but is signaled at the output contact. The alarm image memory always contains
the oldest unacknowledged alarm. The live image appears after manual
acknowledgement.
Manual acknowledgement, alarm image on alarm
If an alarm has occurred, the alarm image (No. 0) is shown with overlaid masks.
The masks will disappear after 5 seconds. The system is still armed. A
subsequent alarm does not store new alarm images, but is signaled at the
output contact. The alarm image memory always contains the oldest
unacknowledged alarm. The live image appears after manual
acknowledgement.
Alarm acknowledgement
If an alarm occurs, the red LED blinks.
The alarm is acknowledged by pressing (> two seconds) the key/rotary switch.
The red LED then switches from blinking to steadily lit (not for AQL).
