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).
