Dual Redundant System
A Dual Redundant system has two interface cards. The system is intended to provide
a secondary interface card in the event of a failure associated with the primary
interface card. When no fault exists the customer ports 1, 2, and 3 on both cards
provide the same contact and alarm data. Internal events data may be different since
this is card specific.
Dominant X1 and Submissive X2
There are two types of dual redundant interface card Dominant and Submissive,
Indentified on the front handle by the letters X1 and X2 respectively. Selection of these
two card types is via a single link LK7 on the PC104 card within the interface card
module.
Dominant LK7 Not Fitted.
