Installation
The OCS1 can be installed in a variety of ceiling environments.The use of the TBCR (Tile Bridge Support Ring) accessory may be desired for many of these environments.
For suspended ceilings, the use of a TBCR is strongly recommended to help support and distribute the weight of the speaker.
In new construction installations, the TBCR, installed before sheetrock, acts as a routing template that ensures an accurate and neat hole for installation. The TBCR can also be used as a support ring in retrofit applications to better distribute the speaker’s clamping forces.
