SETTING UP OR RENAMING ALARMS
The Alarm List pane contains Alarm 01–Alarm 16. You may use an alarm name from the Alarm List, modify the alarm name, or create a new
alarm name. The name must contain fewer than 100 characters and may include only letters, numbers, or spaces. No special characters are
allowed.
To modify an alarm name:
1. Select a name from the Alarms list. The alarm name appears in the “Alarm name” box.
2. Highlight and modify the alarm name or enter a new alarm name.
SELECTING AN ALARM INPUT OPERATING MODE
By default, all alarm inputs are set to operate in the silent alarm mode. This means that the alarm input will not display an alarm message when
triggered.
By default, all alarm inputs are also set to operate in the unsupervised mode. For information about connecting an alarm input to operate in the
unsupervised or supervised mode, refer to Connecting Alarms on page 23.
To enable the alarm input to display an alarm message when triggered:
1. Change the silent alarm mode:
• Turn off silent alarm: If you want to enable the alarm input to display an alarm message, clear Silence Alarm. By default, all alarm
inputs are set to the silent mode (that is, Silence Alarm is selected).
• Turn on silent alarm: If you want to silence the alarm input, click “Silence alarm” to enable the option.
2. If desired, select the specified alarm input to operate in the supervised alarm mode. When an alarm is configured as a supervised alarm,
the DVR5100 maintains a constant electrical current through the alarm circuit. If the resistance changes, the voltage fluctuates from its
normal state, causing the unit to trigger an alarm.
SELECTING ALARM SEVERITY LEVEL
The severity of the alarm determines how alarms are announced and who receives the announcement. To ensure that the correct users receive
information about alarms:
1. Review the Alarm Notification settings on the Users screen.
2. Select the Severity: Minor, Normal (default), Major, and Critical.
NOTE: To receive messages on alarms, the Silence Alarm check box must be cleared.
SETTING ALARM POLARITY
The DVR5100 allows you to set the alarm input’s polarity. By default, the alarm polarity is normally open. You set the polarity to operate as
normally closed. The dwell time is initially set to 5 tenths of a second. Click the Polarity list, and then select the polarity for the specified alarm.
The polarity options are Normally Open (default) or Normally Closed.
