Alarm Contact Connection
There is one Form C alarm contact. This contact has three connections: COM (common), NC (normally
closed) and NO (normally open). 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 NC or NO.
