The police department shall take every reasonable precaution to assure that alarm notifications received are given appropriate attention and are acted upon with dispatch. Nevertheless, the Town shall not be liable for any failure or neglect to respond appropriately upon receipt of an alarm notification, for any failure to discover, after reasonable diligence, a criminal background of an applicant for an alarm license, or the failure or neglect of any person with a license issued pursuant to this chapter or with a franchise in connection with the installation and operation of equipment, the transmission of alarm signals or the relaying of such signals and messages. In the event the Town finds it necessary to order the revocation of an alarm license, the Town shall incur no liability by such action.
