Suitable for retail sales or contractor installation, this low-cost, multi-configurable five-part modular system protects sensitive equipment from lightning damage more completely than the limited ability of surge protectors, in homes, boats, offices and industrial applications. A wall outlet connected module can function by itself as a very capable lightning arrestor for 120 VAC power connected equipment. It also can provide protection to surge protectors as well as other modules, if employed. In the other system modules, an AC connected detector control module and three singularly optional accessory modules, permit advance warning, timed interrupt of AC power as well as coaxial or phone line connection control. Reacting to electromagnetic energy bursts up to approximately two miles away, only very local lightning causes system timer operation, avoiding unnecessary shutdown and resetting of equipment. The calibrated trigger range is adjustable down to approximately +E,fra 1/2+EE mile and a manual reset feature allows restoring all equipment operation should a threat quickly pass.
