Haventech SC-300 Window Intercom

The SC-300 is designed for projects where preserving the glazing is preferred or required. It delivers clear two-way communication without drilling or cutting through the barrier, making it appropriate for new construction, renovation, and specifier-driven retrofit applications.

This no-hole installation approach is increasingly specified where architects, consultants, and facility teams seek to avoid modifications that may affect the integrity, appearance, performance, or acceptance of the window assembly. The SC-300 is well suited for secure counters, protected service windows, and similar transaction points where maintaining the barrier condition is an important project objective.

Optional operating configurations include Push-to-Talk (PTT) and Push-to-Override (PTO). An optional headset jack is also available.

Intercom system only. Window, frame, glazing, and barrier components by others.

Window Intercom — No Hole in Glass

The SC-300 Is Built for How Windows Are Actually Specified Today

Architects, specifiers, and contractors are moving away from cutting holes in glass and possibly voiding the warranty or integrity of the glass. At Haventech, our order volume of this unit has nearly doubled since January 2025.

  • No hole required — glazing stays fully intact
  • Nothing is mounted to the glass to distract from customer interaction
  • Preserves ballistic ratings and window warranties
  • Clean, counter-mounted installation on both sides

Why That Matters
You’re not fighting the spec—you’re working with it. The result is a cleaner installation, fewer approval issues, and a system that fits how modern facilities are designed.

Specified correctly. Safe to recommend. Installed cleanly. Performs as intended.

The SC-300 is built around a commercial-grade audio circuit board using high-quality electronic components for consistent performance and long service life. A high-output speaker is securely mounted to the internal assembly, ensuring reliable audio output.

All components are fastened to a rigid metal chassis with organized wiring and plug-in connectors that simplify servicing if maintenance is ever needed.

The electronics are protected by a heavy aluminum enclosure, reflecting the system’s durable, professional construction.
