Alarm Ports

The switch has four alarm inputs and one alarm output. The alarm setting is open or closed.

•Open means that the normal condition has current flowing through the contact (referred to as a normally closed contact). The alarm is generated when the current stops.

•Closed means that no current flows through the contact (referred to as a normally open contact). The alarm is generated when the current flows.
