Simplex 4905-9997 — white replacement cover with red FIRE lettering for wall-mount TrueAlert speaker/visible (S/V) notification appliances.Simplex lists this part in Table 4, Wall mount S/V replacement covers, of the TrueAlert Multi-Candela Notification Appliance datasheet. The wall-mount S/V housing is a one-piece assembly supplied complete in red or white; the cover is removed with a tool and is sold separately so an installed appliance can be converted to the other color or have a damaged cover replaced. It is a cover only — no speaker, strobe or lens assembly is included. White cover, red FIRE lettering 7 1/4 × 5 × 1 3/8 in. (184 × 127 × 35 mm) For wall-mount multi-candela S/V models 4906-9151 and 4906-9153 TrueAlert non-addressable generation, not TrueAlert ES Check the appliance family before ordering. The red version of this same cover is 4905-9996. The visually similar 4905-9995 (white) and 4905-9994 (red) are covers for the 4903-94xx TrueAlert audible/visible horn/strobe appliances, not for S/Vs, and TrueAlert ES 49-series appliances use their own 49xxC covers instead.
