Can I output an alarm (close the alarm terminal) on a power failure?

If not using relay contact output for control, you can use it as a 4th alarm. This alarm would be the C contact type, therefore by connecting it to the N.C. (normal close) side you can use it as an alarm terminal. Note that when changing the basic specification of the UM33A to 4 relays, the 4th is C contact.
