Product Integration Luminaires and other services can be integrated with System 120. Modular luminaires can be supported directly from the soffit. Where maximum point loads are exceeded see installation advice, the load must be supported independently or from the grid. The SAS pattress system allows the integration of heavier items into the system by distributing the load directly back to the Emac channel eliminating the need for complicated support arms. Further details are available from the SAS technical department.

Security Considerations In areas where it is necessary to restrict access to the ceiling void, System 120 offers a downward demountable tile that clips securely into the supporting grid. Tiles can be removed from the ceiling plane by means of an easy access tool. This is ideal for airports and other security driven environments, including schools and lavatories.

Cleanability As the ceiling tiles are clipped into the supporting grid and with closed butt joints; System 120 is particularly suited to areas where cleanliness and hygiene are important. Upward pressure can be applied to the ceiling as part of a cleaning schedule or to remove stubborn marks. In high humidity environments, such as food preparation, tiles can be painted both sides to ensure tile performance is unaffected.
