3.2 Terminal Block Power Connector

A removable terminal block provides both power and alarm (Normally closed) connections. Power can be provided through dual inputs from separate sources. The alarm relay contact can be wired into an alarm circuit which senses an alarm condition when the contact is broken. The alarm relay is normally closed when there is no alarm condition (both power 1 and power 2 have source power). If either or both power sources have no power input, the alarm relay is open.

The following figure describes a typical connection.
