Alarm Configuration

• AlarmSetThreshold: The trigger level for this alarm. When temperature exceeds

the Alarm Set Threshold, the VMR/NPS can send an alarm (if enabled) and/or begin

Load Shedding (if enabled.) For more information on Load Shedding for the Over

Temperature Alarm, please refer to Section 7.2.1. (Initial Threshold: Default =

110°F or 43°C, Critical Threshold: Default = 120°F or 49°C.)

Note: The Alarm Set Threshold value must be greater than the Alarm Clear

Threshold value. The VMR/NPS will not allow you to define an Alarm Clear

Threshold value that is higher than the Alarm Set Threshold.

• AlarmClearThreshold: Determines how low the temperature must drop in order

for the Alarm condition to be cancelled and for Load Shedding (if enabled) to

occur. For more information on Load Shedding for the Over Temperature Alarm,

please refer to Section 7.2.1. (Initial Threshold: Default = 100°F or 38°C, Critical

Threshold: Default = 110°F or 43°C.)

Note: The System Parameters menu is used to set the temperature format for

the VMR/NPS unit to either Fahrenheit or Celsius as described in Section 5.3.

• ResendDelay: Determines how long the VMR/NPS will wait to resend an email

message generated by this alarm, when the initial attempt to send notification was

unsuccessful. (Default = 60 Minutes.)

• NotifyUponClear: When this item is 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 the temperature has exceeded the trigger value,

and then send a second notification when it determines that the temperature has

fallen below the trigger value. (Default = On.)

• EmailMessage: Enables/Disables email notification for this alarm. (Default = On.)

• Address1,2,and3: These parameters are used to select which of the three email

addresses, defined via the "Email Messages" menu (see Section 5.9.11,) will receive

the email alarm notification messages generated by this alarm. The Address

parameters can be used to select one, or any combination of the addresses defined

via the Email Messages menu. (Default = All On.)

Note: If Email addresses have been previously defined, then the text under the

parameters will list the current, user defined email addresses.

• Subject: This parameter is used to define the text that will appear in the "Subject"

field for all email notification messages generated by this alarm. (Default = "Alarm:

Over Temperature (Initial)" or "Alarm: Over Temperature (Critical)".)

• LoadShedding: Provides access to a submenu, which is used to configure and

enable the Load Shedding feature for the Over Temperature alarms. When Load

Shedding is enabled and properly configured, the VMR/NPS will switch specific,

user-selected plugs On or Off whenever the temperature exceeds the Alarm Set

Threshold value. If the Auto Recovery feature is enabled, the VMR/NPS can

also return these user-selected plugs to their prior status, when the temperature

falls below the Alarm Clear Threshold value. For more information on the Load

Shedding Feature and Auto Recovery, please refer to Section 7.2.1.
