Alarm Configuration
7.1. The Output Contacts
In addition to providing notification when an alarm is generated, the Over Temperature
Alarms, Ping-No-Answer Alarm, Invalid Access Lockout Alarm and Monitor Input Alarm
all offer the option to switch the output contacts on the Control Module AUX Connector
when an alarm is triggered. The output contacts can then be used to activate an
audible alarm or other device in response to these alarms.
When the Contact Output Enable parameter is enabled for any of these alarms, the
Common line will be switched from the Normally Closed contact to the Normally Open
contact in order to drive an attached device.
Figure 7.1 above shows the location of the Normally Closed, Common and Normally
Open contacts on the Control Module AUX Connector.
