§ 4-2-1 PURPOSE AND DEFINITIONS.
   (A)   The purpose of this article is to provide minimum standards and regulations applicable to burglar alarm systems, holdup alarm systems, alarm businesses and alarm users as defined in this article.
   (B)   For the purpose of this article, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
      ALARM BUSINESS. Any business operated by a person for a profit which engages in the activity of altering, installing, leasing, maintaining, repairing, replacing, selling, servicing or responding to a burglar or holdup alarm system, or which causes any of these activities to take place.
      ALARM SYSTEM. An assembly of equipment and devices (or a single device such as a solid state unit which plugs directly into a 110-volt AC line) arranged to signal the presence of a hazard requiring urgent attention and to which the Police Department may be expected to respond. The term ALARM SYSTEM shall include the terms AUTOMATIC HOLDUP ALARM SYSTEM, as that term is hereinafter defined, excluding smoke detectors and automobile alarms.
      ALARM USER. Any person on whose premises an alarm system is maintained within the village, except for proprietary systems. If such a system, however, employs an audible signal emitting sounds or a flashing light or beacon designed to signal persons outside the premises, such system shall be within the definition of “alarm system”, and shall be subject to this article.
      ANNUNCIATOR. The instrumentation on an alarm console at the receiving terminal of a signal line which, through both visual and audible signals, shows when an alarm device at a particular location has been activated, and it shall also indicate line trouble.
      ANSI. Stands for the American National Standards Institution.
      AUTOMATIC DIALING DEVICE. Refers to an alarm system which automatically sends over regular telephone lines, by direct connection or otherwise, a pre-recorded voice message indicating the existence of the emergency situation that the alarm system is designed to detect.
      AUTOMATIC HOLDUP ALARM SYSTEM. An alarm system in which the signal transmission is initiated by the action of the robber.
      BURGLAR ALARM SYSTEM. Refers to an alarm system signaling an entry or attempted entry into the area.
      DIRECT CONNECT. An alarm system which has the capability of transmitting system signals to and receiving them at an agency maintained by the local government, for example, a police communications center.
      DIRECT LINE. A telephone line leading directly from a central station to the communications center of the Police Department that is for use only to report emergency signals on a person to person basis.
      FALSE ALARM. The activation of an alarm system through mechanical failure, malfunction, improper installation, or the negligence of the owner or lessee of an alarm system or of his employees or agents. Such terminology does not include, for example, alarms caused by tornadoes, storms, lightning, telephone line failure or other violent conditions.
      HOLDUP ALARM SYSTEM. Refers to an alarm system signaling a robbery or attempted robbery.
      INTERCONNECT. To connect an alarm system to a communication link, either directly or through a mechanical device that utilizes a standard telephone, for the purpose of using the telephone line to transmit an emergency message upon the activation of the alarm system.
      LOCAL ALARM SYSTEM. Refers to a signaling system which, when activated, causes an audible and/or visual signaling device to be activated in or on the premises within which the system is installed.
      MANUAL HOLDUP ALARM SYSTEM. Refers to an alarm system in which the signal transmission is initiated by the direct action of the person attacked or by an observer of the attack.

If a PROPRIETARY SYSTEM includes a signal line connected directly or by means of an automatic dialing device to a central station, modified central station or answering service, it thereby becomes an “alarm system”, as defined in this article.
      REMOTE SIGNALING SYSTEM. An alarm signaling system which, when activated by an alarm device, transmits a signal from an alarm signaling device to the Police Department, where appropriate action is taken to investigate and respond to the signal.
      SIGNAL LINE. Refers to the transmission line through which the signal passes from one of the elements of the signal transmission to another.
      SPECIAL TRUNKLINE. A telephone line leading into a communications center of an intermediary service and having the primary purpose of handling emergency signals or messages.
