FOR IMMEDIATE RELEASE

PROTECTION ONE REPORTS SECOND QUARTER 1999 RESULTS

CULVER CITY, California, August 12, 1999 - Protection One, Inc. (NYSE: POI),
the nation's second largest provider of life safety and property monitoring
services, today announced its second quarter 1999 financial results.

At June 30 1999, the company's customer base increased slightly over the
previous quarter to 1.65 million and monthly monitoring and service revenue
increased to $42.4 million. Net losses for the second quarter of 1999 totaled
$7.4 million, or $0.06 per share compared to a net loss of $4.6 million, or
$0.04 per share in the first quarter of 1999 (including a non-recurring $2
million severance expense) and net income of $1.4 million or $0.01 per share
in the second quarter of 1998 (including a non-recurring gain of $10.2
million).

Compared to the first quarter 1999, revenues increased 1.5% to $150.8 million
while earnings before interest, taxes, depreciation and amortization (EBITDA)
decreased 5.7% to $58.3 million, or 38.6% of total revenues. The decrease in
EBITDA was a result of higher call center expenses and one-time information
technology expenses both incurred as a result of the company's customer
service initiatives, acquisition and transition expenses as well as a decrease
in the company's rate of growth. Compared to the second quarter 1998, revenues
increased 55.4% while EBITDA increased 73.8%.

Protection One's reported performance was also impacted by increased customer
intangible amortization expense at its European business segment based upon
the results of a recent appraisal. This adjustment reduced Protection One's
earnings by approximately $2.4 million for the first half of the year.
Adjusted net income, defined as net income (as reported) plus goodwill
amortization, was break-even for the second quarter compared to adjusted net
income of $3.9 million or $0.03 per share for the first quarter 1999 and $7.4
million or $0.08 per share for the second quarter 1998.

Cash flow, defined as net income (as reported) plus depreciation and
amortization, was $37.5 million, or $0.29 per share in the second quarter of
1999, compared to $38.1 million or $0.30 per share in the first quarter 1999,
and $29.2 million or $0.31 per share in the second quarter 1998. Second
quarter net annualized attrition was 14.3% and the trailing 12-month net
attrition was 10.5%.

In early 1999, Protection One consolidated monitoring of accounts to central
locations to improve customer service. The execution of this strategy caused
service disruptions that have adversely affected customer service. Protection
One is addressing these customer service issues. In this regard, Protection
One has hired approximately 150 additional service representatives. Protection
One is reviewing the accounting consequences, if any, of this customer service
issue. If a change in the average estimated life of 10 years is determined to
be appropriate, each one year decrease in life would increase annual
amortization expense by about $14 million.

John E. Mack III, chief executive officer of the company, said "Our second
quarter was a transition quarter for us as we continue to evolve toward a less
expensive means of customer creation. We continue to concentrate on lowering
our cost of growth, improving customer service and divesting our non-core
assets. We are making substantial investments in technology and people to
improve our customer service and to reduce attrition."

Protection One received a letter from the Division of Corporation Finance of
the Securities and Exchange Commission on August 11, 1999. The letter raised
questions about the company's financial statements and stated that, in the
view of the staff, there are errors in the financial statements which are
material to Protection One's financial statements. These questions relate to
the methodology used by Protection One to amortize accounts and the allocation
to customers' accounts in the Network Multifamily acquisition. See the
company's annual report on Form 10-K/A and quarterly reports on Form 10-Q
filed with the SEC for further information.

On June 28, 1999, Protection one announced the signing of a definitive
agreement to sell its Mobile Services Group to ATX Technologies, Inc. for
approximately $20 million in cash, plus a note and a preferred investment in
ATX. The sale is expected to result in a one-time approximate $11 million
after-tax gain in the company's third quarter. The company anticipates closing
this transaction by the end of August. Mr. Mack went on to say that
"Protection One is enthusiastic about our continuing investment in ATX as well
as our ability to resell ATX's state of the art telematics product offerings
to our customer base."



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
