From single-room setups to campus-wide IP PA systems — reliable public announcement systems for schools, offices, factories, and malls.
TrustNet Consultancy designs, supplies, and installs public address systems for corporate offices, schools, factories, malls, and public buildings across Kolkata and India. Whether you need a simple public announcement system for a single floor or a fully zoned IP PA system spanning an entire campus, we build it around how your organisation actually communicates day to day.
Our public address systems combine wired and wireless microphones, ceiling and wall-mounted speakers, and centralized control panels — so announcements, emergency alerts, and background audio can all be managed from one point. For larger sites, our IP-based PA systems let you address individual zones or floors independently, without running new cabling through every wall of the building.
Every installation is designed around your building's layout and acoustics first, then built with equipment that's easy for your own staff to operate day-to-day — no specialist training required. We also provide ongoing maintenance and support, so your public address system stays reliable for emergency notifications as well as everyday announcements, for years after installation is complete.
Every element below can be deployed standalone or bundled — designed, installed, and supported by the same TrustNet team.
