Kidde | Genesis WG4 Outdoor Speaker/Strobe, Selectable 15-87 cd, White, Clear Lens, No Marking | EWGSVWN

The Genesis WG4 outdoor speaker/strobe handles fire alarm and mass notification signaling in parking garages, loading docks, process areas, and other wet or harsh environments where standard indoor appliances won't survive. Rated from -31°F to 151°F with a full backplane sealing gasket, it installs to recessed or surface-mounted boxes and wires entirely from room-side.

Built for the commercial installer

Dual-voltage speaker (25V or 70V, switch-selectable) with four wattage taps from 1/4W to 2W covers a wide range of signaling zones without swapping hardware. The standard-output strobe is field-configurable across four settings - 15, 29, 70, or 87 cd (UL 1971 indoor) or 6, 12, 28, 35 cd (UL 1638 outdoor). All settings stay visible through a sealed viewport after the cover goes back on. Synchronization-compatible with Genesis protocols and all Kidde VM, VS, and FX Series panels.
