The LCS 2-D Relay Processing Panel (RPP)

Product Overview

The LCS 2-D is the latest generation of computerized lighting control systems utilizing microprocessor technology. The LCS 2-D offers effective control of the energy consumption in large and small buildings.  The LCS 2-D system is designed for standalone operation, which is programmed through the LCD display on the CPU Board for smaller applications and in a network for larger more complex applications.

The LCS 2-D control system central component is the Relay Processing Panel (RPP). The RPP is capable of supporting up to 32 inputs (e.g., switches) and 32 relay drivers each capable of driving 2 relays. The output relay design will accommodate SPI HID, Panasonic HID or GE-RR7 lighting relays. Inputs are powered by the RPP therefore, no external power is required.  The inputs accommodate contact closure devices such as switches and motion detectors. The LCS 2-D product line includes momentary contact lighting switches.  Each switch has a Dual color LED for on/off status, which is powered by the RPP.

The RPP is designed for flexibility in configuring the inputs and outputs. Output relays can be programmed separately or programmed to “follow” a relay. Inputs are programmable to control multiple output relays. As a network, all inputs and outputs are addressable and programmable from any RPP. Creating a seamless network of panels. Programming is accessible through an RPP (LCD Display), or a laptop plug-in, or a networked PC, or modem. This system’s features include an optional modem connection for off site control, monitoring and troubleshooting.

The scheduling function features a 9-day format. Days 1 to 7 are defined as Monday to Sunday and days 8 and 9 as Holiday schedules. Each day schedule can perform 10 “on” and 10 “off” commands. Every output relay has 9 day scheduling capability.

Scheduled “off” commands can activate a “flicker warning” feature. The “flicker warning” will alert the occupants that the lights are scheduled to turn off.  This allows the occupants time to override the “off” command using a wall mounted switch. The zones controlled by the switch are fully programmable. The extended occupancy time can range from 1 minute to 2 hours.
