Electro-Voice EVID Installation and Wiring, RR Series Mounting Plates, RPK Series Kits

Installation and Wiring

The EVID™ mounting system has been designed so that, if necessary, the installation can be done from beneath the ceiling. In some cases with a suspended ceiling grid, however, it may be easier to access from both the top and bot- tom of the ceiling tile during the installation process.Typical installation hardware needed for either suspended ceilings or sheetrock ceilings is included.The ceiling speaker assembly is held in place by mounting tabs that securely grip the ceiling material. Input wiring is attached to a removable terminal block connector that can be pre-wired if necessary before speaker installation to speed up the installation process.

INSTALLATION NOTE: USE OF OPTIONAL ROUGH-IN ACCESSORIES

For most installations, no additional hardware is needed. However, a two-step installation proce- dure that is sometimes used for installation into sheetrock ceilings can be made easier by the use of the optional RR and RPK series of rough- in accessories before the ceiling material is installed.The rough-in accessories provide a cutout guide when many holes are to be made in a production-line style installation and to ensure the speakers are positioned correctly as the holes are cut in the sheetrock. Depending on the requirements, two types of rough-in accessories are available.

RR Series Mounting Plates

RRseries plates are made of flat sheet metal with holes to attach to the joists or trusses of a build- ing structure.The holes are drilled for nails or screws at 16 inches (406 mm),20 inches (508 mm) and 24 inches (610 mm) on-center.The installer can drill other holes as needed up to a maximum of 24-3/4 inches (630 mm) apart.The sheetrock installs over the plate,and the plate pro- vides a template for a blind cutout of the hole in the sheet rock.The ceiling material is generally cut with a router-type cutting tool,using the plate ring as a cutout guide.The mounting plate is illus- trated in Figure 4.

RPK Series Kits

The RPK series rough-in kit contains a RR series plate with a standard 2 gang electrical box mounted on the top with an attached short length of flexible conduit which connects to the ceiling speaker conduit clamp on the speaker’s rear terminal cover.This accessory allows for rigid conduit to be run to the box on the rough-in plate before the speaker or any sheetrock is installed.After the sheetrock is installed the speak- er can be wired up and mounted all from below the ceiling.The RPK mount system is shown in Figure 5.

INSTALLATION NOTE: CONTROLLING VIBRATION

Because of their high performance, EVID ceiling loudspeakers can generate substantial vibration, which can cause buzzing in loose sections of the ceiling structure. Depending on the charac- ter of the ceiling tile and related components, dampening material may need to be used under the tile rails or the edges of the tiles to eliminate rattles.
