2.3 ALARM FUNCTIONS
The alarm function can be enabled or disabled in the
alarm profile. When motion is detected by a camera or
when an alarm is triggered by an Action/Alarm box
(optional), the alarm function is activated.
In case of an alarm:
Monitor in day mode:
• The monitor selects the respective camera input of
the Alarm/Action box.
• The blinking alarm symbol is displayed on the
monitor screen.
• The power LED starts to blink.
• The alarm output contact is activated (horn, siren or
telephone selector) and a buzzer sounds for default
30 secs (programmable range from 5 sec. to 15 min.).
• The history table is updated with the alarm event.
• Alarm event string is visible at the bottom of the
monitor screen until alarm is acknowledged. You can
manually acknowledge alarms or select auto
acknowledge.
Monitor in night mode (display ON):
Same as in day mode with the exception of:
• An alarm generated in this night mode will be
processed by the system after the entry delay time
has expired. If the system switches over from night to
day during the entry delay time the alarm will not be
processed. Exceptions are special alarms, like tamper
and system alarms, which will always be processed.
Monitor in night mode (display OFF):
Same as in night mode (display ON) with the exception
of:
• The buzzer does not sound.
• To show or reset alarm, switch over from night mode
to day mode.
Monitor in night mode (display ON AT ALARM):
Same as in night mode (display OFF) with the exception
of:
• Monitor display is switched ON if an alarm is
activated and it will display the image of the camera
that has been activated.
• If there is no user activity, the system will
automatically switch back to night mode display
OFF within 15 minutes. If there is user activity, the
user must switch the display off by pressing the Day/
Night Switch.
2.3.1 Reset Alarm
The alarm can be reset in two ways:
Manual reset:
Resets the alarm whenever the ROTARY wheel is
pressed. The monitor returns to the status before the
alarm occurred.
When the cause of the alarm has not been eliminated,
the monitor continues to display the alarm symbol.
When the ROTARY wheel is not pressed during an
alarm, the monitor automatically acknowledges the
alarm after default 30 secs (programmable range from 5
sec. to 15 min.). The monitor returns to the status before
the alarm occurred. The blinking alarm message is dis-
played until the ROTARY wheel is pressed.
Auto acknowledge:
When there is an alarm, the system automatically
acknowledges the alarm after the programmed alarm
duration has expired (can be set from 5 sec. to 15 min).
Note
If the display is in sequence mode during an alarm, it
automatically returns to sequence mode, starting with
the next image after the alarm image.
