Siemens FHD2006-U1 — clear-lens window, Siemens part number S54400-C46-A1, for the outer doors of Cerberus PRO fire-alarm enclosures.
A Cerberus PRO enclosure comprises a back box, an inner door carrying the operating unit and LED option modules, and an outer locking door with one or more openings. The FHD2006-U1 is the rugged Lexan lens that fills such an opening, keeping the panel readable with the outer door closed and locked; Siemens designates its two-window 2HU kit as being for use with LEDs. It fits one way only, held by eight #10-32 lock nuts supplied with it. Quantity follows the door: FHD2001 and FHD2002 doors take one, FHD2003 two, and a 3HU IVC enclosure with an FHD2007 door two.
