King's Chapel auditorium lighting

A failing dimmer system replaced with SpaceLogic C-Bus, a DALI-2 gateway and a custom touchscreen, controlling twenty new LED high bays and two blue stage floods at The King's Chapel in Wellard.

The brief

An old dimmer board, lamps nobody makes, and a room that had outgrown four zones.

What the church had
  • A Dynalite dimmer board that was failing and no longer split the room the way it is used
  • Twenty 400 W metal halide high bays, with replacement lamps no longer available
  • Four zones, controlled from an old panel
What they asked for
  • Dimmable LED lighting across the whole auditorium
  • Five zones, so the lights over the projector screens can be dimmed on their own
  • Controls staff and volunteers can use without training
  • The work done over the school holidays
How the system fits together

One C-Bus network, one controller doing the thinking.

Logic on the controller

The system does the thinking, so nobody has to.

Automatic blue stage lights

Two blue floods behind the stage, switched by a C-Bus relay, come on with any row. Only All Off or Stage Blue turns them off.

Screen and keypad stay in step

The scene highlight follows the lights, whether they're set from the screen, a slider or the wall.

Fault banner

A driver or network fault reported by the gateway puts a red banner on the screen.

Yearly service reminder

An amber banner each October from 2027 prompts the annual service call.

The new enclosure replaced the old Dynalite dimmer board on the same supply. The system was built and tested on the bench at our Osborne Park office before it went to site.

The wall keypad

Quick control by the door, without unlocking the screen.

KeyControls
Row 1Whole front row
Rows 2 to 4Each row on its own
Full HouseAll twenty high bays

Both control points drive the same C-Bus groups, so whatever is set on one shows on the other. Every key dims: tap to switch, hold to dim, with a bar graph and a four-second ramp.

Built on the bench
