The DS-KD-ACF3/S is the stainless steel three-module flush mounting bracket for Hikvision's DS-KD8003 modular door station range.
Like the plastic DS-KD-ACF3, it recesses the door station into the wall and supplies the back box. The difference is the front: the cover plate is stainless steel rather than plastic, which is what you want on a street door, a communal block entrance or a commercial unit where the frame edge is the first thing to take a knock. The gang box behind it stays plastic — it is set into the wall and never sees the weather.
Three-module size gives room for a full build: a DS-KD8003 camera module plus two of the keypad, card reader, nametag or display modules. That is the usual arrangement on apartment blocks and offices where visitors and residents each need their own way in. Fit a DS-KD-BK blanking module in any unused slot.
Rated for -40 °C to 55 °C. Cover plate 337.8 × 124 × 11.5 mm; gang box 320.8 × 107 × 45 mm. For surface mounting in stainless, use the DS-KD-ACW3/S instead.
