The alarm relays of external devices can be either normally opened or normally
closed. The Stinger unit can be configured to sense an alarm condition for the
opening of a normally closed relay, or the closing of a normally open relay. For
information on the configuration of these parameters, see the information about
SNMP alarm support for input relay alarms in the
Stinger Administration Guide
