• Do not exceed 300 feet of CAT-5/16-gauge, 2-conductor wire run from the Central Controller to
any Zone Keypad.
• Label all wiring runs. The Zone Keypads and the Door Station both use CAT-5 wiring, but they use
different signals and voltages. Label the CAT-5 wiring, 18-gauge speaker wire and 16-gauge, 2-
conductor power wire to prevent Zone Keypad wires from being connected to the Door Station
port, or the Zone power cable from being plugged into the Zone speaker port.
• 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.
• Keep all system wires away from objects such as heating and air conditioning ducts, metal
construction plates, and anything else with sharp edges that can damage the wires.
