The System can protect up to 4096 units. Running from the computer are 3/8" cables belting the inside perimeters of the storage buildings and connecting up to 512 doors. A pair of wires, in series with a lightning suppressor, rise, from a switch mounted at the top of each door and snap, onto the overhead belt cable in accordance with a preprinted stick-on label. WHAM installation is largely a one-person job. A new installer can wire about 30 doors a day; a more experienced person, twice that.

Unlike any other system, all electronics reside solely inside an PC-based controller. There are no active electronics in the keypads nor enroute to the switches on the storage doors. Electronics are entirely eliminated from building corridors and exteriors where they are difficult to service and vulnerable to lightning, moisture and tampering.

We require observance of U.L and N.E.C. grounding and lightning protection standards for the structures and metal conduits which contain the System. This is a prudent precaution which enhances the ability of your System to survive the worst environmental hazards, electrical storms.
