Simplex 49WPBB-AVVOWR — weatherproof surface-mount back box for 49 Series wall audible/visible (AV) and visible-only (VO) notification appliances, red.
An outdoor-listed notification appliance holds that listing only in the back box it was listed with. A standard indoor box leaves the terminals exposed to driven rain and washdown, so on a parking deck, loading dock, covered walkway or plant area the weatherproof box is part of the assembly, not an accessory to it. The part number decodes as 49 Series WeatherProof Back Box, AV or VO, Wall, Red.
- Rated NEMA 3R for outdoor and wet-location mounting
- Serves both AV and VO wall appliances, so one box number covers a mixed site
- Surface mount, red finish; gasketed with conduit knockouts
Back box only — the notification appliance is a separate order. Simplex publishes separate weatherproof appliance families, so confirm the exact appliance catalogue number and its listed back box against the installation documentation before ordering; substituting an unlisted box voids the outdoor designation.
