Planning the Installation Before you begin the installation, consider the major factors discussed in the following sections to ensure that the installation of the VoiceLift System is as smooth and trouble free as possible and that the result meets the needs of the users. Placement of the receiver (sensor location) is very important for optimal performance of the VoiceLift System.
Room Considerations The following room factors are important to consider when you are planning the installation of a VoiceLift system: Interference and noise sources Infrared and radio frequency noise can reduce the performance of the microphone system. To minimize noise in the system, avoid mounting the VoiceLift receiver near the following items: • Lighting, fluorescent or incandescent — Keep the receiver at least 2 feet (61 centimeters) away from a light source.
Line-of-sight obstructions between microphone and receiver A clear line of sight between the microphone and the receiver is critical for best performance.
Reflection Line of sight from the microphone to the receiver is ideal; however, reflection of the IR signal also plays a part in the coverage for most rooms. For example, if the speaker with the microphone is facing a screen, the IR signal may reflect off the screen surface to the receiver in the middle of the room. Ideal conditions for reflection are light colored, smooth surfaces (for example, white drywall).
Receiver Location The best location to mount the receiver is on the ceiling in the center of the classroom. If the receiver is wall-mounted, center it on the wall between 6 feet (1.8 meters) and 12 feet (3.6 meters) from the floor. These locations maximize the coverage and line of sight to the microphone. Avoid the corners of the room, alcoves, bays, or sheltered areas that can restrict coverage. If the ceiling is over 12 feet (3.
PoleVault Switcher Location The PoleVault switcher can be mounted anywhere in the room, because the volume controls are on the microphone. However, placing the switcher near the ceiling makes cabling and upgrading to a full PoleVault system easier. WARNING: Structural ceiling failure could cause serious injury or death. Check the structural ceiling to ensure that it can handle a load four times the weight of the final setup.

Stage 1: Mounting the Receiver This stage consists of installing the VLR 102 receiver in a drop ceiling or on a wall. Receiver Housing and Back Plate Back Plate Conduit Knockouts (2) Raceway Knockouts (2) Receiver Housing Figure 9. Receiver Housing and Back Plate Where it goes: The housing attaches to the receiver dome, and the back plate mounts to a ceiling tile or a wall. What it does: Protects the receiver base plate and connectors.
Stage 1a: Installing the VoiceLift Receiver in a Drop Ceiling (page 17) Stage 1b: Installing the VoiceLift Receiver to a Junction Box (page 18) Stage 1c: Installing the VoiceLift Receiver to a Wall (page 19) Stage 1d: Installing the VoiceLift Receiver on a Pole (page 21) Figure 11. Diagrams of Stage 1 Mounting Options NOTE: Observe all local and national building and safety codes to ensure that the installation meets all regulatory standards.
Stage 1a — Installing the Receiver in a Drop Ceiling 1. Cut a hole in the ceiling tile. a. Remove the ceiling tile in which the receiver will be installed. b. Determine the receiver location, then cut a hole in the ceiling tile 2 to 3.5 inches (5 to 9 cm) in diameter, using a circular (shown at right) or other type of saw (saws are not included).
Stage 1b — Installing the Receiver to a Junction Box 1. Install the junction box. • Install the junction or ceiling box (not included) flush with the mounting surface (follow the instructions provided with the junction box). • Use a one-gang plaster ring (Raco 772) if the junction box is larger than one‑gang. WARNING: Risk of electric shock. Improper installation may result in electrical shock or serious injury.
Stage 1c — Installing the Receiver on a Wall or Other Hard Surface 1. Install a raceway if needed. If using a raceway for the cables, install it at the appropriate location on the mounting surface. NOTE: Raceway knockouts on the receiver housing fit common types of raceways such as the Wiremold 500/700 series and the Wiremold 2400 series. Follow the instructions provided by the manufacturer to install the raceway. a Install the raceway (if needed). b Mark mounting screw locations in the surface. 2.
