How to Make the Connections
• Carefully strip insulation on wires from 3/16 to 1/4 inch. Do not strip more than 1/4 inch of insulation off
of wire. Strip approximately 1/4 inch of insulation from each wire conductor.
• Attach all wires to their specific location as labeled on the connectors and as shown in the wiring
connection detail.
• DO NOT confuse the 16-gauge power wire with the 18-gauge speaker wires. Crossing these wires will result
in damage to the speakers and zone keypads.
• Insert the Zone Keypad into the rough-in box. Make sure that none of the cables are pinched and all are clear
of the box.
• Screw the Zone Keypad into place using the 4 screws included with each unit.
• Snap the faceplate into place. The faceplates are interchangeable and they snap on and off easily.
Installing the Speakers
Allowable Speaker Configuration
• Use 8-ohm speakers only.
• DO NOT connect more than one pair of 8-ohm speakers to each Zone Keypad.
• DO NOT daisy-chain speakers. Each zone is designed to drive only one pair of 8-ohm speakers at the same time.
• DO NOT confuse the 16-gauge power wire with the 18-gauge speaker wires. Crossing these wires will result
in damage to the speakers and zone keypads.
Location Considerations
• DO NOT install speakers in outside walls.
• DO NOT install speakers in stud cavities that contain 120/240V appliance wiring, or within 18 inches of
dimmers, security wiring, and other control wiring.
• DO NOT place speakers in air return cavities or in walls that contain plumbing.
• Place in-wall speakers six to eight feet apart, but no closer than two feet to any adjacent wall or ceiling.
• DO NOT place in-wall speakers in the same stud space as in-wall speakers for other zones.
• Ceiling speakers should be spaced six feet apart for eight-foot ceilings and eight feet apart for ten-foot or greater
ceilings. Place them no closer than two feet to any adjacent wall.
• DO NOT place in-ceiling speakers close to fluorescent lights.
• Some type of protection is required for the back of in-ceiling speakers if blown insulation is used.
Wiring Considerations
• Use 18-gauge, 2-conductor wires for connecting the speakers to the Zone Keypad.
• Keep all speaker wiring away from 120/240V wires, security, dimmers, and other control wiring.
• DO NOT staple wires. Stapled wires can cause shorts. Also, if a wire has been cut too short at one end, stapling
makes it impossible to pull additional wire through the wall.
• DO NOT splice wires. Splices are unreliable and defeat the signal isolation properties of the wires.
