HARDWARE COMPATIBILITY
Note for ULC Listed installations:
Products or components of products, which perform communications functions only, must
comply with the requirements applicable to communications equipment as specified in CAN/
CSA –C22.2 No. 60950-1, Information Technology Equipment-Safety - Part 1: General
Requirements. Where network interfaces, such as the following, are internal to the subscriber
control unit or receiver, compliance to CAN/CSA –C22.2 No. 60950-1 is adequate. Such
components include, but are not limited to: Hubs; Routers; Network interface devices; Third
party communications service providers; Digital subscriber line (DSL) modems; and Cable
modems.
Note for UL Listed installations:
Packet switched data network interface equipment, manufactured by other than the burglar
alarm equipment manufacturer, that is not required for the processing of the signals must be
evaluated to the applicable requirements of the Standard for Information Technology
Equipment – Safety – Part 1: General Requirements, UL 60950-1, either as burglar alarm
equipment or communication equipment.
