ALARM OUTPUT
When the alarm output is to be transmitted remotely via outdoor cables, a surge protector for the signal line is required.
Choose a circuit breaker with alarm output. Configure a logical OR sequence so that the alarm trips when both or either
of the MAKF, MAKN or the breaker alarm trips.
