The Alarm Relay Card

Overview	The Alarm Relay Card mounts on, and is driven by, the SPS. It has 3 relays each
	providing one set of voltage-free contacts.
	The relays are able to be configured under custom control, but the default operation is for
	system status, i.e. Fault (Trouble), Isolate (Supervisory), and Alarm, respectively. These
	are commonly used to drive the Brigade signalling.
