Gentlemen and Ms. Hercot:

      You  have  requested  our  opinion,  as  counsel  to  Shared  Technologies
Fairchild Inc. (the  "Company"),  with respect to certain  matters in connection
with a proposed offering of 250,000 shares of the Company's Common Stock,  $.004
par value (the "Shares"), by the Company,  pursuant to options granted and to be
granted under the Company's 1994 Director Option Plan (the "Plan"). The offering
is to be made pursuant to a Registration  Statement on Form S-8 to be filed with
the  Securities  and  Exchange  Commission  on  or  about  June  27,  1997  (the
"Registration Statement").

      In rendering this opinion we have  reviewed,  among other  documents,  the
Plan documents,  the Company's Restated Certificate of Incorporation and Amended
and  Restated  Bylaws,  as  amended  to  date,  and  certifications  as  to  the
proceedings of the Company's stockholders and Board of Directors relating to the
authorization and issuance of the Shares. We have also considered such statutes,
rules and regulations as we have deemed relevant for the purposes hereof.

      Based on the foregoing, it is our opinion that:

      1. The Company is duly incorporated, validly existing and in good standing
under the laws of the State of Delaware.

      2. The Shares to be sold by the Company,  when issued and sold pursuant to
the Plan and options granted  thereunder,  will be legally  authorized,  validly
issued, fully paid and nonassessable.

      We hereby consent to the filing of this opinion letter as Exhibit 5 to the
Registration Statement.

                                                  Very truly yours,


                                                  /s/ Gadsby & Hannah LLP
