NOTE: The terms "normally open" and "normally closed" correspond to the de-energized positions of the relay contacts.

The relays are energized during normal (non-alarm) channel operation, so the "normally open" position is closed

and the "normally closed" position is open during non-alarm channel operation. The relays are de-energized

during alarms or when power to the channel is interrupted.
