Parameter Alarm Connection
The Parameter Alarm Form C alarm provides notification if a monitored parameter exceeds any of the
programmed thresholds. This contact has three connections:
•
NC (normally closed)
•
NO (normally open)
•
COM (common)
Connection can be made directly to the facility's alarm reporting system. If multiple units are used, then
these contacts can be connected in series or parallel, depending on the requirements for the facility's
wiring of NC (normally closed)or NO (normally open).
