Evolution Series Poke-Thru Devices are UL Listed and Classified to U.S. and Canadian safety standards to the

ollowing conditions:

f

The 8STC Poke-Thru Stem with the 8CTC or 8CT Service Head Fitting, and the 8ATCP, 8ATP, 8ATC or 8AT factory assembled
Poke-Thru devices are for use with 1-, 1 1/2-, or 2- hour rated unprotected reinforced concrete floors and 1-, 1 1/2-, or 2- hour
rated floors employing unprotected steel floor units and concrete topping (D900 Series Designs), or concrete floors with suspended
ceilings. (Fire resistive designs with suspended ceilings should have provisions for accessibility in the ceiling area below the Poke­Thru fittings).

The assembled Poke-Thru stem and service fitting will not reduce the ratings of the floor assembly when the thickness and type

f concrete (required for the specific rating) are within the specified limits and the fittings are installed as specified:

o

1. Spacing – Minimum of 2' [610mm] OC and not more than one unit per 65 sq. ft. [6 m

2

] of floor area in each span.

2. Concrete – Minimum thickness of structural concrete topping of 2 1/4" [57mm] over metal deck or a minimum 3" [76mm]
thick reinforced concrete slab. Unit weight of concrete to be 110 to 155 pcf.

3. Installation – Mounted in a 8" [203mm] diameter hole in concrete per installation instructions accompanying
the fittings. For use with power circuits, data and/or audio/visual cables as tabulated below:
