LIGHTNING DETECTION AND ADVANCE STORM WARNING SYSTEM:  SD-250  ELK II

     A unique, state of the art electronic storm warning system which satisfies the requirements of The Bureau of Mines, O.S.H.A., and the U.S. Army Corps of Engineers.                                                Reduces exposure to, and potential hazard for people who are outside such as blasters, construction and mining crews, window cleaners, airport and marina personnel, golfers and swimmers, or anyone who needs advanced warning of  approaching electrical storms. The SD-250 provides this advanced warning by detecting  the electric discharges of lightning.  Proximity of electrical discharges can be monitored as the distance of lightening strikes are indicated by the range lamps and an alarm can be set to go off should the storm come closer than the distance set by the operator. When tripped a built in "squawking" alarm sounds and twin lamps alternately flash until reset by the operator. The system can also be configured to activate a variety of external warning devices such as sirens, strobe lamps, transmitters, computer interfaces, etc.   The system comes complete in a watertight case with a smart battery charger and a system testing generator.
