Exhibit 99.1

Protection One Closes Sale of its Mobile Services Group to ATX Technologies

Both Companies to Collaborate on Promoting Telematics Services

     CULVER CITY, Calif.--(BUSINESS WIRE)--Aug. 25, 1999--Protection One Inc.
(NYSE:POI - news), one of the nation's leading providers of life safety and
property monitoring services and 85% owned by Western Resources (NYSE:WR -
news), Wednesday announced the closing of the sale of its Mobile Services
Group.

     The Mobile Services Group was sold for approximately $21 million in
cash, plus a note and a preferred investment in ATX. The companies had
announced on June 28, 1999, that they entered into a definitive agreement.

     Protection One is continuing to deliver telematics services through a
reseller arrangement with ATX, which was executed contemporaneous with the
closing. Telematics is a relatively new service industry that combines
wireless and location identification technologies with call center-based
convenience. From emergency response services to navigation assistance to
vehicle theft recovery, telematics provides drivers and fleet managers with
immediate access to location-based information.

     ``Our Mobile Services Group is a pioneer in the emerging business of
providing security and information primarily in the OEM automobile industry
and wireless communications markets,'' said John E. Mack III, chief executive
officer of Protection One.

     ``The combination of ATX's expertise in the telematics market and our
Mobile Services Group will position the two companies as a major competitor in
the telematics industry and should result in upside equity potential for
Protection One. In addition to realizing a significant return on our
investment and retaining a modest equity interest, this divestiture of a non-
core asset continues Protection One's strategy to focus on its residential
monitored security services,'' added Mack.

     ``This transaction provides ATX Technologies the base to be the mobile
information service provider of choice to the wireless industry, building on
our pioneering leadership in the automotive market,'' said Steven W. Riebel,
president and CEO of ATX Technologies. ``We look forward to continued
collaboration with one of the largest security firms in the country.''

     The combined company will provide mobile services to a number of major
companies, including Mercedes-Benz North America; Ford Motor Company including
Ford, Jaguar and Lincoln-Mercury; the Infiniti Division of Nissan Motor
Company; Greyhound Lines Inc.; Fujitsu Ten Corp. of America; Mitsubishi
Electric Corporation; and Alpine Electronics of America.


     ATX will maintain Protection One's existing Mobile Services Group
operations in Irving, Texas. Credit Suisse First Boston acted as financial
advisor to Protection One in this transaction.

     Protection One, one of the leading residential security alarm companies
in the United States, provides monitoring and related security services to
more than 1.6 million residential and commercial subscribers in North America
and Europe.

     Western Resources is a consumer services company with interests in
monitored security and energy. Western Resources has total assets of more than
$8 billion. Western Resources' utility companies, KPL and KGE, provide
electric service to approximately 600,000 customers in Kansas.

     Through its ownership in ONEOK Inc. (NYSE:OKE - news), a Tulsa-based
natural gas company, Western Resources has a 45 percent interest in the eighth
largest natural gas distribution company in the nation, serving more than 1
million customers. For more information about Western Resources and its

     ATX Technologies has headquarters in San Antonio, Texas, with offices in
Dallas, Detroit, and Los Angeles. ATX provides leading-edge telematics
services for mobile applications to consumer-oriented and commercial markets
for asset protection, fleet tracking, emergency response, routing assistance,
stolen vehicle tracking and other location-specific information.

     The company pioneered in-vehicle and automotive after-market
applications of telematics beginning in 1996 and in 1999 introduced telematics
services in wireless communications.
