Acoustic Scope

Public Address Systems & Emergency Voice Evacuation (EVCS)

PSG ENGINEERING PTE LTD delivers commercial PA system installations engineered for high speech intelligibility and seamless background music (BGM) paging. In compliance with Singapore SCDF Fire Code, our Voice Evacuation Systems interface directly with Fire Alarm Control Panels (FACP) to trigger automated emergency evacuation announcements.

Multi-Zone Commercial Paging & BGM Matrices

Zone-selectable paging microphones, digital signal processors (DSP), ambient noise sensing microphones, and high-fidelity ceiling/wall loudspeakers.

SCDF Emergency Voice Evacuation (EVCS) Interfacing

Direct relay integration with Main Fire Alarm Control Panels (FACP) to instantly override background audio and broadcast phased emergency evacuation messages during fire alerts.

Speaker Line Impedance & Acoustic Intelligibility Tuning

100V line impedance monitoring, speaker loop short-circuit protection, and STI (Speech Intelligibility Index) audio calibration.
