FOR IMMEDIATE RELEASE

            PROTECTION ONE REPORTS STRONG RESULTS FOR FOURTH QUARTER
                            AND 1998 YEAR END RESULTS

         Culver City, California, January 27, 1999 - Protection One, Inc. (NYSE:
POI), the second largest national provider of security alarm monitoring and
related services, today announced its results for the fourth quarter and year
end 1998.

         In the fourth quarter, revenues increased to $144.0 million, reflecting
a full quarter contribution from several acquisitions that closed at the end of
the third quarter as well as a continued increase in the subscriber production
of the dealer program. The Company had 1.5 million subscribers and monthly
recurring revenue of $37.9 million at December 31, 1998. Earnings before
interest, taxes, depreciation and amortization (EBITDA) rose to $58.0 million,
or 40.3% of total revenues. The Company reported net income of $0.5 million or
$0.004 per share, for the fourth quarter. Cash flow, defined as net income plus
depreciation and amortization, was $39.3 million or $0.31 per share for the
quarter ended December 31, 1998.

         For the fiscal year ended December 31, 1998, the Company generated
total revenues, EBITDA and cash flow, defined as net income plus depreciation
and amortization, of $421.1 million, $178.4 million and $132.0 million
respectively. The Company reported $10.4 million of net income, or $0.10 per
share for 1998.

         James M. Mackenzie, president & chief executive officer, said "1998 was
an outstanding year for Protection One. Through various strategic acquisitions,
we established a major presence in the multifamily alarm business. We grew our
presence in the Canadian, United Kingdom and Continental European alarm markets
and continued to achieve strong growth in our North American alarm division.
Further, we will become the leader in the high-growth personal emergency
response services through our pending acquisition of Lifeline Systems, Inc. We
anticipate closing the Lifeline transaction in the second quarter of 1999."

         Mr. Mackenzie continued, "During the year, our subscriber base more
than doubled to more than 1.5 million as a result of acquisitions and strong
organic growth through our dealer program. We also made significant strides in
integrating our acquisitions and strengthening our infrastructure. By
successfully accessing the capital markets on several occasions during 1998,
Protection One is well capitalized for 1999 and beyond."

                  Additionally, the Company announced that its chief financial
officer Monty Cornell has given notice of his intent to accept a position with
another company and relocate to his hometown of Chicago. Effective immediately,
the new acting CFO for the Company is John E. Mack, III who is currently
executive vice president and chief strategic officer. Mack is one of the
original founding partners of Protection One dating back to 1991. He has an
undergraduate degree from Stanford University and a Masters Degree in Business
Administration from The Anderson Graduate School of Management at UCLA.

         Protection One, the second largest security alarm company in the United
States, provides monitoring and related security services to more that 1.5
million residential and commercial subscribers worldwide.
