NTP-G72 Provision External Alarms and Controls on the Alarm Interface Controller-International Card
Step 6 In the Alarm Contacts area, click the Add Extension radio button if you are using the AEP. Clicking
this option will choose the External Alarm input/output type and the AEP extension type; it will give
you access to 16 external alarm contacts.
Step 7 If you did not click Add Extension, in the Input/Output area choose either External Alarm or
External Control. (External Alarm will limit your input/output options as explained in Step 6.) Choosing
External Control will enable both external alarms and external controls. This will convert four of the
external alarm contacts to external controls, leaving 12 available external control contacts. The
extension type for both options is AEP.
Step 8 Click Apply.
Step 9 If you are provisioning external alarms, click the External Alarms tab (Figure 8-10). If you are not
provisioning external alarms, skip Steps 10 through 12 and go to Step 13.

Step 10
For external alarms, complete the following fields:
• Enabled—Check the check box to activate the fields for the alarm input number.
• Alarm Type—Choose an alarm type from the drop-down list.
• Severity—Choose a severity from the drop-down list.
The severity determines the alarm’s severity in the Alarms and History tabs and determines whether
the LEDs are activated. Critical (CR), Major (MJ), and Minor (MN) alarms activate the LEDs. Not
Alarmed (NA) and Not Reported (NR) events do not activate LEDs, but do report the information
in CTC.
• Virtual Wire—Choose the virtual wire number from the drop-down list if you want to assign the
external device to a virtual wire. Otherwise, do not change the None default.
• Raised When—From the drop-down list, choose the contact condition (open or closed) that triggers
the alarm.
