CHAPTER 7: Alarm Configuration

Note that both the Initial Threshold menus and Critical Threshold menus offer essentially the same parameters, but the parameters defined for each alarm are separate and unique. Therefore, parameters defined for the Critical Threshold Alarm will not be applied to the Initial Threshold Alarm and vice versa. Both the Over Temperature (Initial Threshold) alarm and the Over Temperature (Critical Threshold) alarm offer the following parameters:

•Trigger Enable: 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.

•Alarm Set Threshold: The trigger level for this alarm. When temperature exceeds the Alarm Set Threshold, the Outlet Managed PDU 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 = 90°F or 32°C, Critical Threshold: Default = 100°F or 38°C.)

•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 = 80°F or 27°C, Critical Threshold: Default = 90°F or 38°C.)

Note:

The System Parameters menu is used to set the temperature format for the Outlet Managed PDU to either Fahrenheit or Celsius as described in Section 5.3.

•Resend Delay: Determines how long the Outlet Managed PDU 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 Outlet Managed PDU will send additional notification when the situation that caused the alarm has been corrected. For example, when Notify Upon Clear is enabled, the Outlet Managed PDU 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.)
