Colour-matched plate for black installations. Gent gives the black as the natural colour of the moulding rather than a coating, and publishes no other difference from the white part: same 136 mm diameter, same 8 mm section, same obligation under any strobe or sounder head.
Specify it wherever a black base is specified: the plate is the wider component and shows at the ceiling line if colours are mixed.

Compatibility
Pairs with the S4BK-700 base under black alarm heads, principally S4BK-711-V and S4BK-711-V-VAD-HPR. Since no black version of the S4-701 combined pack exists, a black alarm device is always three lines on the order: head, base, plate. The white equivalent is S4-705.
Installation
Fits like the white plate, to the back box ahead of the base. Count carefully at estimate stage: five plates per pack against one base per pack means the two black numbers never divide evenly.
