Redundant Power Input ：
The design of the redundant power input allows two power supplies to
deliver power to the NSM-208GP to increase reliability. Each of the power
supplies will have the capacity to run the switch on its own when the other
one goes down. The alarm relay can be used to connect with a buzzer to
produce an alarm in the case of a power failure. It is recommended to use
dual power input if the switch will be used in heavy load applications.
