5 Alarm Relay

The PD-IES008x-DCxx and PD-IES206x-DCxx alarm relay contacts can be wired into an external alarm circuit, which notifies if one of the redundant power sources has no power or a fault. The alarm relay contacts are normally open on proper operation; in an alarm condition it latches into a closed state. An external circuit must consist of a power supply and a load which indicates the alarm condition as a buzzer, lamp and so on.
