The AMD8TC Series Poke-Thru Devices are UL Listed and Classified to U.S. and Canadian safety
standards to the following conditions:
The AMD8STC Poke-Thru stem with the AMD8CTC service head fitting, the AMD8ATC factory assembled Poke-Thru device,
and the AMD8APTC abandonment fitting are for use with 1, 1-1/2, or 2 hr rated unprotected reinforced concrete floors and 1, 1-1/2
or 2 hr 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 Poke-Thru fittings).
The assembled Poke-Thru stem and service fitting or the abandonment fittings will not reduce the ratings of the floor assembly
when the thickness and type of concrete (required for the specific rating) are within the specified limits and the fittings are
installed as specified:
1. – Spacing – Minimum of 2' [610mm] OC and not more than one unit per 65 sq ft [6 sq. m] 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 in. thick reinforced concrete slab. Unit weight of concrete to be 110 to 155 pcf.
3. – Installation – Mounted in a 4" [102mm] diameter core-drilled hole in concrete per installation instructions accompanying
the fittings or abandonment fittings. For use with power circuits, date and/or telephone cables as tabulated below:
The “TC” suffix letters indicate that device may be installed on tile or carpet covered concrete floors. All catalog numbers may
have an “RT” suffix to indicate units supplied with Ortronics, Inc. communication modules and accessories.
(A) Maximum number of 22 AWG conductors in low-voltage compartment of Poke-Thru fitting (4 pair cables have 8 conduc-
tors). When conductors larger than No. 22 AWG are used, the aggregate cross-sectional area of the copper conductors
shall not exceed the aggregate cross-sectional area of the 22 AWG conductors permitted in the low-voltage compartment.
FLOOR COVERINGS: The Poke-Thru device is fire rated for carpet or wood covered floors, tile floor coverings up to 3/4" [19.1mm]
maximum thickness, and linoleum floor coverings up to a maximum 1/8" [3.2mm] thickness. For other floor coverings not listed
above, consult factory.
