LCP128
TM Setup and Maintenance Guide 5
Introduction
System Specifications
LCP128 is a lighting control system designed for commercial buildings. It consists of up to 8 dimming panels
and up to 32 control stations. Control stations can be wallstations, key switches, contact closure input and
output devices (OMX-AV), contact closure output devices (OMX-CCO-8), or building management system
interfaces (OMX-RS232). All panels and control stations are connected by a digital communications link. Refer
to the LCP128 Installation Guide for wiring details. Other system specifications are described below.
Time Clock
• 7 weekly schedules.
• Up to 40 holiday schedules.
• Each holiday schedule can be 1-90 days.
• Up to 500 time clock events.
• Maximum of 25 time clock events per day.
• Up to 32 scenes and 1 Off scene.
• With each time clock event or control station input, you can select which circuits turn on or off and, for dimming
circuits, set specific dimming levels.
• Time clock events can occur at a fixed time of day or at a time relative to sunrise or sunset (astronomical).
• Events can be placed on either a weekly schedule (for example, occurring every Monday) or a holiday schedule
(for example, occurring only on January 1).
• Holiday schedules override weekly schedules.
• Time clock events can start and end afterhours mode. Afterhours is an energy saving mode where lights that
are set to be off will automatically, after a period of time, turn themselves off. Afterhours mode can be
temporarily overridden by any control station action. See STEP 5 for more information.
• Time clock events can enable and disable control stations.
Control Station - Wallstation
Wallstation buttons can be individually programmed to:
• Select a scene or custom scene. A scene is a combination of preset lighting levels used to automatically turn
on, off, or dim a circuit or group of circuits. Each time the wallstation button is pressed, the circuits go to the
programmed scene settings.
• Raise or lower circuits. Dimming circuits progressively raise or lower as long as the button is pressed. Circuits
stay at this setting until another event or control station input occurs.
• Toggle circuits on and off. Each press of the button alternates between turning the circuits on and off. If the
circuits are in a mixed state (some on and some off), the lights turn on.
• Turn off with a time delay. When the button is pressed, the circuits turn off after a preset amount of time.
• Enable or disable time clock.
Control Station - Key Switch
• The key switch (NTOMX-KS) can be programmed for clockwise and counterclockwise turns and with the same
functions as a wallstation button.
Control Station - Contact Closure Inputs
Two contact closure inputs are available on each LCP128 controller – more are available by purchasing a Lutron
OMX-AV control station (five inputs per OMX-AV that can be added anywhere on the digital control station link).
• The contact closure inputs can be programmed on the open and/or closure of the contact to perform the same
functions as a wallstation button.
