• 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.
Installing the Door Station
• Run CAT-5 wire from the Door Station to the Central Controller location.
• The recommended height for Door Station rough-in box is 48-inches from the ground to the bottom
of the box.
• An ME 3 back box is required for new construction. It is shipped separately.
