Alarm Configuration
7.4. The Lost Voltage (Line In) Alarm
The Lost Voltage (Line In) Alarm can provide notification after the power supply to the
VMR/NPS unit has been interrupted.
Notes:
• The Lost Voltage (Line In) alarm is only available on VMR/NPS units that
include two input power lines.
• The Lost Voltage (Line In) alarm will provide notification when one of the
available power supplies is lost or disconnected. This alarm will not function
if all input power to the VMR/NPS unit is lost. To provide notification when
all input power is lost and restored, please use the Power Cycle Alarm as
described in Section 7.7.
• In order for the VMR/NPS to provide alarm notification via Email,
communication parameters must first be defined as described in
Section 5.9.11.
• In order for the VMR/NPS to provide alarm notification via Syslog Message,
Syslog parameters must first be defined and Syslog Messages must be
enabled as described in Section 5.9.2 and Section 11.
• In order for the VMR/NPS to provide alarm notification via SNMP Trap, SNMP
parameters must first be defined, and SNMP Traps must be enabled as
described in Section 5.9.7 and Section 12.
To configure the Lost Voltage (Line In) Alarm, you must access the VMR/NPS command
mode using a password that permits Administrator Level commands. The Lost Voltage
Alarm Configuration menu offers the following parameters:
• TriggerEnable: Enables/Disables the trigger for this alarm. When Disabled, this
alarm will be suppressed. (Default = On.)
Note: To cancel an alarm without correcting the condition that caused the
alarm, simply toggle the Trigger Enable parameter Off and then back On again.
• ResendDelay: Determines how long the VMR/NPS will wait to resend an email
message generated by this alarm, when the initial attempt to send the notification
was unsuccessful. (Default = 60 Minutes.)
• NotifyUponClear: When enabled, the VMR/NPS will send additional notification
when the situation that caused the alarm has been corrected. For example, when
Notify Upon Clear is enabled, the VMR/NPS will send initial notification when it
detects that one of it's power supplies has been lost or disconnected, and then
send a second notification when it determines that power has been restored.
(Default = On.)
• EmailMessage: Enables/Disables email notification for this alarm. (Default = On.)
Note: The Email Message parameter offers four different options: On, Off, On
(Copy to All Triggers) or Off (Copy to All Triggers). If either of the "Copy to All
Triggers" options is selected, then email notification for all other alarms will be
switched On or Off as indicated by this parameter. For example, If "Off (Copy
to All Triggers)" is selected, then Email notification will be disabled for all other
alarms too.
