I,VE BEEN ASKED TO SOME FIRE ALARM IN A 1 HR RATING,ANY IDEA IF RIGID CONDUIT WILL PROVIDE THIS.
THX NEIL

Don,t know what i was thinking it,s the wire in the conduit that has to be 1 hr rated.

I thought the requirement for fire alarm survivability was 2 hour, not 1. Either way, you are correct, the conduit (regardless of type) will only give you about 20 minutes.
