This document is the user manual for the SM 40 Surveillance Centre, which introduces the basic use and operation process of the surveillance centre.
The SM40 Surveillance Centre monitors amplifiers, loudspeakers and cabling in large public‑address systems, detecting faults and generating error messages that can be displayed, printed or sent to external warning devices. It supports up to 4096 monitoring devices, pilot‑tone testing and automatic switching to spare amplifiers.
The system is rack‑mounted, microprocessor‑controlled and expandable with optional Extension Frames (LBB 1360). Installation guidelines cover unpacking, wiring, power requirements, connector checks and safety precautions.
