Trigger: Trigger an alarm output or stop an alarm output. As there is only one alarm 
output available, the “Trigger All” button just triggers the one output. However, if an 
IP camera is connected to the recorder, then the outputs of the camera will also be 
listed. 
Clear All: Stop all alarm outputs at once.

Buzzer settings 
When an alarm is triggered by the system or a camera, the recorder can be set up to 
respond with a warning buzzer. You can modify the time during which the warning 
buzzer sounds for both system and camera alarm. For example, when a physical alarm 
input is continuously triggered, the buzzer will time out after the time specified.  
Select Alarm & Event Setup > Buzzer Settings and select a buzzer time limit for the 
system and camera alarms. Select Mute, 5 s, 10 s, 20 s, 30 s, 60 s, 120 s, 240 s, or 
Constant. Default is Constant. 
Event notification 
You can select the alarm and event notifications to be included in the event hint icon of 
the alarm center displayed in live view. Clicking the icon opens the window of the alarm 
center that lists the detected alarm and event notifications. See “Status information” on 
page 28 for information on the status icon displayed in the OSD.
