1 Scope

1.1 These requirements cover the design, manufacture, implementation, and support of automation system units and accessories intended to be used in central-stations and proprietary stations for the reception, processing, dispatch, responses, and record keeping of property protection and life safety signals. Automated monitoring systems are a combination of computerized automation software and subsystems, including LAN/WAN network communications under control of the central-station. The monitoring system units and accessories and subsystems provide all the monitoring, control, communications audible indications and visual display functions of the system and shall meet all applicable requirements as specified by this Standard.

1.2 These requirements also cover special considerations for proprietary and national industrial security system application software.

1.3 These requirements do not cover hardware receiver units that are evaluated under separate equipment standards such as the Standard for Proprietary Burglar Alarm Units and Systems, UL 1076, the Standard for Central-Station Burglar Alarm Units, UL 1610, the Standard for Control Units and Accessories for Fire Alarm Systems, UL 864, and the Standard for Digital Alarm Communicator System Units, UL 1635.

1.4 These requirements do not cover the building needed to house the automation system, the staffing requirements, the power system(s), wiring expectations, spare parts, support policies, the specifics required by the Monitoring Equivalent Weight (MEW) factor, and any other requirement that falls outside the specifics of this automation standard. This information can be found within the latest edition of Standard for Central-Station Alarm Services, UL 827.

1 Scope

1.1 These requirements cover computerized central-station automation systems intended for use in central-station, proprietary, remote and subsidiary burglar-, and fire-alarm applications for the purpose of automating the signal handling and processing of change-of-status signals generated by receivers. In case of failure of an automation system, the receiving equipment is relied on for receiving and recording change-of-status signals and the provision of an audible and visual signal that identifies the source and type of signal that requires operator attention. These systems are intended to be installed in accordance with the following:

a) The National Electrical Code, NFPA 70;

b) The National Fire Alarm Code, NFPA 72; and

c) The Standard for Central-Station Alarm Services, UL 827.

1.2 A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
