Lifeline 2-Hour Fire Rated Cable Omni Cable introduces a cost effective means for two-hour protection against fire and water.

Draka Lifeline cables are designed for use in critical circuits where the cable must be able to function under conditions of direct exposure to fire and water. Lifeline safeguards critical fire alarm systems and emergency circuits by providing complete cable operation to fire pumps and power panels that provide lighting and other powered functions.

Most of the electrical systems that we use today are powered by standard electrical cables. Even the systems that we depend on in times of danger and emergency are powered by standard interconnect, control or power cables. Most of these cables do not have a tolerance for high temperature or fire, which is exactly why Draka Cableteq USA introduced a cost effective means for two-hour protection against fire and water.

Unlike other protective cable, Lifeline is a flexible, non-armored cable that allows fire controls and alarm circuits to continue to function in extreme environments. Lifeline Cables are also designed for critical circuit applications in fire alarm systems including detection, notification, signaling line circuits and communications. Lifeline Cable provides for active surveillance and data retrieval, firefighter communications and firefighter elevators.

Ceramified Silicone Technology The Lifeline family of cables are produced with electrical grade ceramified silicone rubber which is proven to protect the critical circuits for your emergency systems against attack by fire and water. Under the conditions of fire or extreme heat, the ceramified silicone rubber hardens into an insulating glass-like

structure, which protects the conductors against fire and water which may be present during firefighting efforts.

To ensure the quality and reliability of Lifeline cables most critical component, all silicone rubber is compounded in-house at Draka Cableteq USA utilizing proprietary formulations. All Lifeline cables utilize ceramified silicone technology to achieve their fire rating. The use of silicone ensures that each Lifeline cable is flexible and has equivalent or improved electrical performance over its non-fire rated counterpart.

All Lifeline cables are two hour rated per UL 2196 Standard for Tests of Fire Resistive Cables.

There are three main types of Lifeline cable.

Lifeline RHW, Lifeline CIC, and Lifeline CI.

• • •

Lifeline RHW - 600 volt power cable for use in feeder or branch circuits Lifeline CIC - Type FPL & NPLF cable for use in Fire Alarm Systems Lifeline CI - Type FPLR-CI cable for use without conduit in Fire Alarm Systems

Lifeline RHW is a composite insulation system that achieves the smallest diameter and highest temperature rating of any ceramified silicone fire rated cable. Without the need for additional fire barrier tapes, Lifeline RHW is UL listed as type RHH/RHW-2 for 90°C and UL classified with a 2-hour fire rating per UL 2196 - "Standard for Tests for Fire Resistive Cables"

Innovative and Flexible for the most demanding applications

Lifeline RHW replaces Mineral Insulated (MI) cable, concrete encasement or construction of unnecessary fire barriers as the optimum way to protect critical circuits against fire and water.

Lifeline CIC is a cost effective means of providing survivability as required by the National Fire Alarm Code (NFPA 72).

Additionally, it can dramatically increase the reliability of any fire alarm system when it is exposed to fire and water.

Lifeline CIC is flexible and easy to install without the need for any special tools, hardware or instructions.

Another benefit of the fire rated construction is extremely low capacitance improving system performance and eliminating the need for special midcap cables.

All Lifeline CI cables are qualified to UL 2196 - "Standard for Tests for Fire Resistive Cables" which includes a two hour fire exposure (accepted as representing an intense, fully developed fire within a building), water exposure and several electrical tests and monitoring to assure its circuit integrity performance.

All of this in a robust non-armored fire alarm cable that is flexible, easy to install and requires no special procedures to meet code requirements.

SHEALY ELECTRICAL TURNS SUNLIGHT INTO ENERGY SAVINGS New Columbia and Corporate campus uses daylighting as a natural solution Daylighting is recognized as a best practice in energy codes and industry standards due to its potential to generate high energy savings using a control strategy called daylight harvesting.

The concept of daylight harvesting is simple.

Digital photo sensors detect daylight levels and automatically adjust the output level of electric lighting to create a balance. The goal is energy savings.

Shealy Electrical Wholesalers’ new corporate campus has taken advantage of daylight harvesting lighting controls, as well as a variety of other technologies, in an effort to make daylighting a sustainable design strategy.

As daylight increases, photocontrols and occupancy sensors switch the controlled lights off or send signals to the dimming ballasts to automatically adjust indoor lighting to match changes in ambient daylight. This strategy is estimated to save 40 to 70% of energy. Accomplishing this type of energy savings has been made possible through the combination of Lutron and Wattstopper/ Legrand products.

Shealy Electrical utilizes Lutron’s revolutionary light control called EcoSystem. Ecosystem is a lighting control system that is comprised of digital dimming ballasts, controls and environmental sensors. Together, those components increase space flexibility,

increase occupant comfort and productivity, and reduce maintenance costs.

EcoSystem is designed for office spaces and K-12/university classrooms, where lighting accounts for 30% to 44% of electricity usage.

These applications benefit from EcoSystem’s energy savings through personal controls including wall stations in combination with environmental sensors such as daylight and occupancy/vacancy sensors. EcoSystem allows Shealy Electrical to take advantage of available natural light and adjust electric lighting smoothly and continuously throughout the day. Occupancy/Vacancy settings slowly dim lights to low levels or turn lights off when a space is unoccupied.

Selected indoor lighting and all outdoor lighting systems at Shealy Electrical are controlled by the Wattstopper/Legrand Lighting Integrator Complete Control (LIC) system. LIC is a low voltage, relay based lighting control panel. Panel interiors are configured as 8, 24 or 48 relay capacity.

Each LIC panel stores the user generated programming in non volatile memory housed within the Complete Control intelligence card.

This controller monitors all inputs and uses a unique priority based logic engine to generate the appropriate load response (relay control) based on combinations of input triggers that can include schedules, override switches, occupancy sensors, photocells and signals from other building systems.

The LIC system is a full featured networked control system that provides the maximum flexibility for lighting control by providing both panel based and distributed load control options.

A digital communication bus allows user programming generated at the WinControl workstation to be transferred to the panels where it runs autonomously. Once loaded into the panels, the lighting automation features operate without the need for an online PC. This distributed processing capability ensures a high degree of reliability.

“We are excited about our new location, but even more excited about the innovative, energy efficient systems that are being utilized.” says David White, Executive VP of Shealy Electrical Wholesalers. “You have to walk the walk if you're going to talk the talk. Every day we sing the praises of energy efficient lighting products in an effort to help customers reduce energy costs, become "greener", and stay current with lighting technology. Now we speak from experience and are anxious to have customers visit our new location and witness firsthand the benefits of these innovative products.”

Needless to say, Shealy Electrical‘s new Corporate campus is a sight to see. For more information about innovative energy solutions and systems, or for a campus tour, contact your Shealy Salesperson today!

PAGE 6 SHEDDING LIGHT ON LIGHTING AUDITS

FALL 2009, VOL. 3, ISSUE 2

Maximize your energy savings while maintaining and improving lighting and operational quality Building owners are always concerned about upgrading facilities and decreasing operating costs. The most important facet of reducing operating costs may be upgrading the lighting system that most people outside of the building never see.

The largest single component of a commercial building’s electricity bill is lighting. Overall, utility costs are the largest expense per square foot for commercial buildings when compared to cleaning, repairs/maintenance, roads/grounds, security and administration.

Lighting audits are the simplest and most effective way to evaluate the current lighting system and identify methods of reducing long-term operating costs. A lighting audit provides detailed retrofit, conversion or replacement fixture recommendations complete with the cost of the project, payback analysis and annual energy savings. If required, task-specific light level readings before and after a retrofit may be required to ensure levels are adequate after the lighting system is changed or modified.

For more details about lighting audits, please contact your Shealy Salesperson today.

Lighting retrofits provide a multitude of benefits Energy Savings Lighting retrofits can greatly reduce energy consumption and lower your energy bills while maintaining light levels and quality by upgrading light components to more efficient and advanced technologies Improved Lighting Quality Lighting retrofits can improve lighting quality by targeting problem areas with specific design considerations to overcome lighting issues. Newer technologies also add increased reliability and longevity to the lighting system.

These newer technologies provide better lighting quality characteristics such as improved color, reduced flicker and greater light output.

Reduced Maintenance and labor costs Improvements in lighting technologies have led to increased lifetimes for components that will result in fewer failures and lengthen the time between maintenance activities Pollution Reduction By consuming less electricity, your facility will help reduce the demand and associated emissions from off-site power generation. These harmful emissions include CO2 and various other greenhouse gases.

Common lighting problems Incandescent Bulbs Incandescent lamps are one of the most inefficient lighting sources available. Old-fashion incandescent bulbs can be replaced with compact fluorescent lamps (CFLs) to achieve a 75% energy savings. CFLs last 8-10 times longer than incandescent lamps, which will reduce maintenance costs, labor and inventory demands.

Source Efficiency Lamp Life $/Year* A-Lamp 15 Lumens/ 1,000 $23.36 Watt hours CFL 60 Lumens/ 10,000 $5.84 Watt hours *Cost/year based on a comparison of a 100W Incandescent bulb and a 25 W CFL, 8 hours per day, 365 days a year, at a utility rate of $.08 per kWh T12 Fluorescent lamps T12 Lamps are an older technology and should be replaced with T8 lamps. T8 lamps provide superior lighting quality and last longer, while improving efficiency by 30%. They also operate on electronic ballasts that are more efficient and produce much less heat than older magnetic ballasts.

Lighting left on when the space is unoccupied Areas where lights are often left on while the space is unoccupied should have an occupancy sensor or a timing switch installed. These control devices are relatively simple retrofits and can represent large energy saving opportunities.

Lights Flicker Flickering lamps often indicate a faulty ballast or lamp.

Before replacing the ballast, determine whether or not it is utilizing T12 lamp technology. If it is, this might be an opportune time to implement a retrofit.

Old Exit Signs Exit signs offer one of the easiest ways to reduce costs and save energy due to their long operating hours and traditionally poor source efficacy. It is strongly recommended that exit signs that utilize either incandescent or CFL sources should be replaced with LED-sourced exit signs.

Integration of a photocell into the lighting will turn the lights off when daylight reaches a present level. A timer switch can also be integrated into the exterior lighting circuit and will turn the lights on and off according to an inputted schedule.

Simple change-outs and lighting control options Dimming Lighting accounts for about 44% of electricity used in office buildings and 56% of electricity usage in education buildings.

Dimming your lights 25% saves 20% in energy, incandescent bulbs last 20 times longer if dimmed by 50%, and replacing a standard light switch with a dimmer can save up to $30 per year.

Wireless Occupancy Sensors An ideal solution for retrofit applications, a completely wireless system can cost up to 50% less than a conventional hard-wire system. Occupancy Sensors detect motion that keeps lights on while the space is being occupied. An automatic shutoff time can be adjusted to a user’s personal requirements.

Traditional Technology Occupancy Sensors Traditional occupancy sensors do a good job of simply turning lights on when a room is occupied and off when it is not. Time and sensitivity adjustments fine tune them.

Daylight Harvesting An easy-to-use means of automatically achieving a comfortable level of illumination throughout the work day and driving energy savings by maximizing the incorporation of natural light levels. Pairing daylight harvesting controls with electronic dimming ballasts will help optimize performance and sustainability. Combining use with energy-efficient fluorescent T8 or T5 lamps will further maximize performance and efficiency.

Compact & Regular Fluorescent Lamps Compact fluorescent bulbs are now available for almost every socket.

LED Lamps LED lamps and fixtures are becoming more prevalent. LEDs last 10 times longer than compact fluorescent lamps and

133 times longer than standard incandescent lamps. LED lamps run cool, and because they don’t contain mercury, they are easy to dispose of and environmentally safe.

Ballasts Reliable and energy efficient, high frequency electronic ballasts for T8 and T12 Fluorescent lamps offer energy-saving properties. Ballast change outs are ideal for general office lighting, conference, meeting and board room applications, indirect and decorative lighting.
