Transformers are fitted to match the loudspeakers to 100V line systems.

A fixing bracket is attached to the surface or ceiling; the housing is pushed over the bracket and then held to it by springs.

Omega SurfaceVA - 6W, 100V - Voice Alarm

Similar to the Omega Surface, the VA version is fitted with a ceramic terminal block, DC blocking capacitor and thermal fuse. It has fire retardant linking wires, and complies with BS5839:Part8:1998. The terminal block capacitor and transformer are mounted on the fixing bracket, which has two, side-mounted, cable access points. As a result the bracket may be installed and wired as a first fix and then the loudspeaker housing can be attached later by connecting the three linking wires with push-on connectors. The housing is held to the bracket by fast-fit springs.

Specifications and accessories are otherwise as the Omega Surface, excepting Weight: 1.85kg.
