Is there a UL listed system for elevator call button in shaft wall
I'm installing an elevator call button in an existing 2-hour elevator shaft wall and want to maintain the 2-hour fire rating. Wondering if there's an approved UL system for elevator call buttons.

Hello unfortunately there is not a UL listed system for that. Please see below on how to submit for an Engineering Judgement (EJ).
Thank you,
