A- Foolproof ceiling compatibility

The standard ST series fits in grid ceiling with up to 1½" Tee's. More common in surgery suites, these structural Tee's prevent doors frames in standard troffers, from opening. ST luminaires also can be field converted from grid to flange or flange to grid. Costly problems and project delays associated with the most common ordering errors are thus eliminated.

B- Control of Conducted EMI

Electromagnetic interference can be conducted back through power lines and cause interference with sensitive medical equipment. When a separate protected circuit is not provided, a filter in the luminaire itself is required. ST fixtures use a custom designed filter for each lamp circuit to ensure compliance with the strict 461 C&D military standard for conducted EMI. Up to 3 suppressors can be accommodated in the ST’s unique, dual wireway design.

C- 30 Year Door Lens/Design

ST fixtures are built to last the 30+ year expected life cycle of the surgical suite. A one-piece heavy gauge steel door frame, powder coated after fabrication, is standard on all ST fixtures (frames may also be specified in brushed stainless steel). Alkco’s proprietary inverted "V" profile lens aids light distribution and eliminates sagging. These features, in combination with heavy-duty cam latching and hinging ensure that ST fixtures stand up to repeated cleaning/relamping cycles. In fact, Alkco warranties the frame/lens assembly for the life of the installation.
