I am working on a job with a few exterior doors that will not be used as egress/emergency exits. Therefore it is my understanding according to NFPA 188.8.131.52 (see attached) that I need to provide an Illuminated NO EXIT sign above these doors. However every engineer I have talked to has never heard of this rule and I am having trouble finding one of these NO EXIT signs online that conform to these rules? Could anyone point me to some documentation that may clear things up for me?
