I am trying to find a CT with Normally Open ( NO) auxiliary contacts that is listed for use on life safety systems. This CT will monitor a Smoke Exhaust Fan (SEF) and is linked to the Fire Alarm System. I have been able to locate a Hawkeye 938 Series that will perform the functions I need, but this is not listed. I would deeply appreciate any help that can be provided on this matter.

What listing and by who? Within UL, that is usually referring to Fire Alarm equipment. A CT would not be a specific Fire Alarm device, although it obviously might be used in one. If you are building a system, UL will probably list the entire system, not an individual components within it. Have you asked UL?
