V. Control ? Emergency Lighting Circuits
700.20 Switch Requirements.
The switch or switches installed in emergency lighting circuits shall be arranged so that only authorized persons have control of emergency lighting.
Exception No. 1: Where two or more single-throw switches are connected in parallel to control a single circuit, at least one of these switches shall be accessible only to authorized persons.
Exception No. 2: Additional switches that act only to put emergency lights into operation but not disconnect them shall be permissible.
Switches connected in series or 3- and 4-way switches shall not be used.
Does this mean that a hall light in a hospital that is on the emergency generator can not be on a 3-way switch?
