Intercom Upgrade – Christchurch Block of Flats

Faulty Speech Module Call-Out • Recommended System Upgrade • New Fermax Skyline Installed

We recently attended a service call at a residential block of flats in Christchurch where the existing intercom speech module was reported as faulty. On inspection it was clear that the unit was aged and no longer reliable, and due to the system’s condition we recommended a full upgrade to a more modern and maintainable solution.

What Was Done

To restore full, dependable visitor access and resident communication, we carried out the following works:

  • Removed the old, faulty speech module that was causing unreliable operation.
  • Supplied and fitted a new Fermax Skyline 5-button trade entry panel — a robust and user-friendly intercom panel with clear button labelling and professional finish.
  • Installed 5 x new handsets, one for each flat, to provide consistent audio performance and reliable communication from the entrance panel.
  • Tested the entire system to ensure all buttons, handsets and the panel operated correctly after the upgrade.

Benefits of the Upgrade

✔ Dependable communication: New panel and handsets give residents reliable entry control and peace of mind.
✔ Modern and serviceable equipment: Fermax Skyline systems have good parts availability and are easy to maintain or expand.
✔ Improved resident experience: Clearer audio and fresh hardware reduce mis-dials and no-response calls.
✔ Future-ready: System is now ready for future panel expansions or handset replacements as needed without awkward legacy interfaces.

If you’re experiencing unclear intercom audio, failing speech modules, or legacy equipment that’s becoming unreliable, an upgrade like this not only restores functionality — it often improves user satisfaction and makes future servicing far easier.
