Hey Guys,
I'm about to bid on a fairly large job for a new customer. Part of it involves providing service for the elevator emergency phones, and that is what I am worried about. There are two issues here:
1. How does the cable get from the hoist room to the elevator car, or should I just provide some sort of termination in the hoist room and leave the rest to the elevator guys?
2. This is in a heavy industrial building that is fairly old. As a result, cable will need to be run along the ceiling and through THICK concrete floors or walls at some points. Obviously I'll be using plenum rated cable for this. There are several other issues through:
- Will I need to use fire block for the holes? If so, please indicate what products you like to use.
- Should I insert conduit into my drilled holes to prevent cable abrasion? (methinks this is a "vibrating building" from heavy forklifts and such)
Any and all comments are appreciated. I'd especially like to know what the NEC says about fire blocking.
Thanks, Jason
