Kidde WG4WF-HVMHC — Genesis WG4 outdoor-rated horn strobe, white housing, FIRE marking, high-candela strobe.
One low-profile sealed appliance covers wet and harsh locations such as parking garages and process areas as well as ordinary indoor space. A slide switch picks one of four candela steps and stays readable through a sealed viewport after the cover closes.

WG4RF-HVMHC is the identical appliance in red and WG4WN-HVMHC the white unmarked version; every figure above is shared, because the ordering table separates those rows by colour and marking alone. The near-miss is WG4WF-HVMC, standard candela at 15, 29, 70 and 87 cd; WG4WF-H is horn only.
