     WESTERN RESOURCES CONSIDERING ALTERNATIVES 
     TO TYCO OFFER AND RIGHTS AS ADT SHAREOWNER
     
     WESTERN RESOURCES MAILS OFFER 
     TO ADT SHAREOWNERS
     
        TOPEKA, Kansas, March 18, 1997 (7:00 am CST) -- Western Resources 
     (NYSE:WR) announced today that it has mailed the details of its offer 
     to acquire ADT Limited, to the ADT shareowners.  
        In response to questions yesterday concerning the announcement of a 
     proposal by Tyco International Ltd. to merge with ADT, Western 
     Resources chairman and chief executive officer, John E. Hayes, Jr., 
     said, "Over the next few days we will be reviewing the Tyco offer.  We 
     are also considering our alternatives to the offer and assessing our 
     rights as ADT shareowners."
        Western Resources has scheduled a special meeting of its 
     shareowners for April 24, 1997, to consider the ADT acquisition.  ADT 
     has scheduled a meeting of its shareowners on the Western Resources 
     proposal for July 8, 1997, but Western Resources has asked a federal 
     district court in Florida to order that meeting held sooner.
