SCHEDULE 13D/A

This Amendment No. 1 to the Schedule 13D (this “Amendment”) is being filed on behalf of Prescott Group Capital Management, L.L.C., an Oklahoma limited liability company (“Prescott Capital”), Prescott Group Aggressive Small Cap, L.P., an Oklahoma limited partnership (“Prescott Small Cap”), Prescott Group Aggressive Small Cap II, L.P., an Oklahoma limited partnership (“Prescott Small Cap II” and, together with Prescott Small Cap, the “Small Cap Funds”), and Mr. Phil Frohlich, the principal of Prescott Capital, relating to Ordinary Shares, NIS 0.1 Par Value (the “Ordinary Shares”), of Magal Security Systems Ltd., an Israeli company (the “Issuer”).

This Amendment relates to the Ordinary Shares purchased by the Small Cap Funds through the account of Prescott Group Aggressive Small Cap Master Fund, G.P., an Oklahoma general partnership (“Prescott Master Fund”), of which the Small Cap Funds are the general partners. Prescott Capital serves as the general partner of the Small Cap Funds and may direct the Small Cap Funds, the general partners of Prescott Master Fund, to direct the vote and disposition of the 524,927 Ordinary Shares held by the Prescott Master Fund. As the principal of Prescott Capital, Mr. Frohlich may direct the vote and disposition of the 524,927 Ordinary Shares held by Prescott Master Fund.

The Ordinary Shares held by the Reporting Persons (as defined below) reported on this Amendment were previously reported on a Schedule 13G/A filed with the Securities Exchange Commission on February 9, 2009. This Amendment is being filed to report that the Reporting Persons no longer own 5% of the outstanding Ordinary Shares of the Issuer.

Item 1. Security and Issuer

Securities acquired: Ordinary Shares, NIS 0.1 Par Value (the “Ordinary Shares”).

Issuer:	Magal Security Systems Ltd.
	P.O. Box 70, Industrial Zone
	Yehud 56100, Israel

Item 2. Identity and Background

(a) This Amendment is jointly filed by Prescott Capital, Prescott Small Cap, Prescott Small Cap II and Mr. Phil Frohlich. Because Mr. Frohlich is the managing member of Prescott Capital, which is the general partner of the Small Cap Funds (with Mr. Frohlich and Prescott Capital hereinafter referred to as the “Controlling Persons”), the Controlling Persons may be deemed, pursuant to Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Act”), to be the beneficial owners of all of the Ordinary Shares held by the Small Cap Funds. The Reporting Persons (as hereinafter defined) are filing this Amendment jointly, as they may be considered a “group” under Section 13(d)(3) of the Act. However, neither the fact of this filing nor anything contained herein shall be deemed to be an admission by the Reporting Persons that such a group exists.

Page 6 of 10

(b) The principal place of business for each of the Reporting Persons is 1924 South Utica, Suite #1120, Tulsa, Oklahoma 74104.

(c) The principal occupation of Mr. Frohlich is serving as the managing member of Prescott Capital. The principal business of Prescott Capital is acting as the general partner of the Small Cap Funds. The principal business of the Small Cap Funds is investing in securities.

(d) During the last five years, none of the Reporting Persons have been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors).

(e) During the last five years, none of the Reporting Persons have been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and, as a result of such proceeding, were or are subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f) Prescott Capital and the Small Cap Funds are organized under the laws of the State of Oklahoma. Mr. Frohlich is a citizen of the United States of America.

Item 3. Source and Amount of Funds

As of January 28, 2011, the Small Cap Funds had invested $4,762,405 (inclusive of brokerage commissions) in Ordinary Shares of the Issuer. The source of these funds was the working capital of the Small Cap Funds.

Item 4. Purpose of the Transaction

The Small Cap Funds (together with Phil Frohlich and Prescott Capital, the “Reporting Persons”) purchased the Ordinary Shares based on the belief that such securities, when purchased, were undervalued and represented an attractive investment opportunity. Although the Reporting Persons have no specific plan or proposal to acquire or dispose of the Ordinary Shares, consistent with their investment purpose, the Reporting Persons at any time and from time to time may acquire additional Ordinary Shares or dispose of any or all of their Ordinary Shares depending upon an ongoing evaluation of the investment in the Ordinary Shares, prevailing market conditions, other investment opportunities, liquidity requirements of the Reporting Persons and/or other investment considerations.

The purpose of the acquisition of the Ordinary Shares was for investment, and the acquisitions of the Ordinary Shares were made in the ordinary course of business and were not made for the purpose of acquiring control of the Issuer.

Also, consistent with the investment purpose, the Reporting Persons may engage in communications with one or more shareholders of the Issuer, one or more officers of the Issuer and/or one or more members of the board of directors of the Issuer and/or one or more representatives or regulators of the Issuer regarding the Issuer, including, but not limited to, its operations. The Reporting Persons may discuss ideas that, if effected, may result in any of the following: the acquisition by persons of additional Ordinary Shares of the Issuer, an extraordinary corporate transaction involving the Issuer and/or changes in the board of directors or management of the Issuer.

Page 7 of 10

Except to the extent the foregoing may be deemed a plan or proposal, the Reporting Persons have no plans or proposals which relate to, or could result in, any of the matters referred to in paragraphs (a) through (j), inclusive, of the instructions to Item 4 of Schedule 13D. The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto.

Item 5. Interest in Securities of the Issuer

(a) The aggregate percentage of Ordinary Shares reported to be owned by the Reporting Persons is based upon 10,546,548 Ordinary Shares outstanding, which is the total number of Ordinary Shares outstanding as of December 21, 2010, as reported in the Issuer’s Form F-1 filed with the Securities and Exchange Commission on December 21, 2010.

As of January 28, 2011, the Small Cap Funds beneficially owned 524,927 Ordinary Shares, representing approximately 4.9% of the issued and outstanding Ordinary Shares of the Issuer.

Prescott Capital, as the general partner of the Small Cap Funds, may also be deemed to beneficially own the 524,927 Ordinary Shares held by the Small Cap Funds, representing approximately 4.9% of the issued and outstanding Ordinary Shares of the Issuer.

In addition, Mr. Frohlich, as managing member of Prescott Capital, the general partner of the Small Cap Funds, may also be deemed to beneficially own the 524,927 Ordinary Shares beneficially owned by the Small Cap Funds, representing approximately 4.9% of the issued and outstanding Ordinary Shares of the Issuer.

Prescott Capital and Mr. Frohlich disclaim beneficial ownership of the Ordinary Shares held by the Small Cap Funds except to the extent of their pecuniary interest therein.

(b) By virtue of his position with Prescott Capital and the Small Cap Funds, Mr. Frohlich has the sole power to vote and dispose of the Ordinary Shares owned by the Small Cap Funds reported in this Amendment.

The filing of this Amendment shall not be construed as admission that Prescott Capital or Mr. Frohlich is, for the purposes of Section 13(d) or 13(g) of the Act, the beneficial owner of any of the 524,927 Ordinary Shares owned by the Small Cap Funds. Pursuant to Rule 13d-4, Prescott Capital and Mr. Frohlich disclaim all such beneficial ownership.

(c) Annex A attached hereto lists all transactions in the Ordinary Shares during the past sixty (60) days by the Reporting Persons. The transactions in the Ordinary Shares were effected in the open market.

(d) No person other than the Reporting Persons is known to have the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, the Ordinary Shares.

Page 8 of 10

(e) As of January 26, 2011, the Reporting Persons ceased to be the beneficial owner of five percent (5%) or more of the Ordinary Shares of the Issuer.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer

Other than as described herein, there are no contracts, arrangements, understandings or relationships among the Reporting Persons, or between the Reporting Persons and any other person, with respect to the securities of the Issuer.
