R.I. Gen. Laws § 5-57-27

(a) Within seventy-two (72) hours after receipt of the license certificate, the licensee shall cause the license certificate to be posted and displayed at all times in a conspicuous place in the principal office of the licensee within the state. Copies of the license certificate shall also be displayed at all times in any other offices within the state where the alarm business transacts business with its customers, so that all persons visiting that place or places may readily see the license. Those license certificates or copies shall be subject to inspection at all reasonable times by the licensing authority.

(b) It is unlawful for any person holding a license certificate to knowingly and willfully post that license certificate or permit that license certificate to be posted upon premises other than those described in the license certificate or to knowingly and willfully alter that license certificate. Each license certificate shall be surrendered to the licensing authority within seventy-two (72) hours after it is revoked or after the licensee ceases to do business, subject to § 5-57-20(b). If the licensing authority or a court of competent jurisdiction has pending before it any matter relating to the renewal, revocation, or transfer of a license, the licensee is not required to surrender the license until the matter has been adjudicated and all appeals have been exhausted. When the licensee receives final notice that its license is revoked, a copy of that notice shall be displayed and posted in close proximity to the license certificate until the licensee terminates its operations.
