the remote access feature with T1.317 commands or with
EasyView. There are no visual or audible alarms on the CPS shelf

The contact closures must be isolated from frame ground. These
connections are not fused, and improper use may result in damage
to the CPS shelf and/or the ES648 control unit.
Examples
A fan that generates an isolated contact closure because it has failed or
