Lamp selection and spacing between units is closely tied to mounting height. Once the mounting height ofthe application has been determined, use the chart below to select the lamp that optimizes the layout. Thefixture spacing for each mounting height is given for both one footcandle average requirements and onefootcandle minimum requirements, depending on your local code requirements.

Assumptions to arrive at these spacings: 6' wide path of egress in 15' wide aisle of 200'X200' open warehouse with reflectances = 10/10/10. One footcandle averagerequirement also meets .1 footcandle minimum and 40:1 max. to min. ratio as required by Life Safety Code. Visit our website at www.lithonia.com/indura for IES formatted filesused to generate the spacing listed above.

Composite VersusSealed-Beam Lamps

Sealed-beam lamps have long been thespecified lamp choice for optimumperformance in the emergency segment of thelighting industry. In the past, composite lampshave offered reduced performance at aneconomical price.

Indura composite lamps offer the best value bysignificantly exceeding the performance ofsealed-beam lamps at the composite lamp price.High performance krypton composite lampsprovide 20-37% more light output than theequivalent incandescent lamps. Halogen 12W-50W lamps are available for applications whereeven higher mounting heights are required.

In addition, the beam pattern for the compositelamps is field adjustable to a spot, medium orflood setting by simply adjusting the bezel ofthe lamp. The adjustability is somewhatanalogous to the adjustability of a Mag-Light®

(see picture at top right). The adjustibility of thelamps allows customers to optimizeperformance for different mounting heightsand code requirements.

Beam Pattern Adjustability

The composite lamps can be adjusted by simplyrotating the lamp bezel past the appropriatestop. After analyzing the spacing informationfor most composite halogen lamps, the spotposition normally will work best for onefootcandle average requirements, and themedium position normally will work best forone footcandle minimum requirements. Thecomposite krypton lamp performs best in themedium position. The flood position normallywill be reserved for composite incandescentlamps.

Advantages of Utilizing RemoteHeads

Remote heads reduce the number of units,minimizing the number of batteries on the job,resulting in lower maintenance costs.

Remote heads are smaller and less obtrusivethan a complete unit. This is important ifaesthetics are a primary concern.

In addition, remote heads can reduce initialproduct cost, especially in environments thatrequire special ratings such as wet location or inareas where ambient temperatures can diminishbattery capacity or life. In many instances, theunit with battery and electronics can beinstalled in a “normal” or controlledenvironment with the remote heads located inthe areas that require special ratings.

Remote Heads

Advantages of UsingSelf-Contained Units

If remote loads are not required, product costcan be reduced by using 6-volt self-contained(with battery) units. In most instances, a 6-voltproduct is less expensive than a 12-volt or 24-volt product. Choose the capacity to operate thetwo lamps selected from the lamp chart (seepage 4) that maximizes spacing.

Self-contained units diversify your emergencypower sources. If a self-contained unit fails, itaffects a much smaller area than if a unitrunning several remotes fails.

In addition, self-contained units may reduceinstallation wiring costs by eliminating the lowvoltage circuit required to connect the remoteheads.

Selecting 6-, 12- or 24-Volt Units

If remote heads are to be incorporated, firstdetermine the number of remote lamps to beoperated by each unit. Choose a 12-volt or 24-volt product according to circuit run length andload requirements. Reference the voltage dropinformation supplied with this guide (see page7). The length of run is increased approxi-mately four times by using 12-volt instead of 6-volt. It is increased another four times by using24-volt instead of 12-volt.

Terminal Blocks

Terminal blocks are provided to simplify theconnection of remote heads to the emergencyunit. Units of 100-watt capacity or less (smallhousing) are equipped with one terminal blockcapable of accepting up to 10-gauge wire. Unitsof 150-watt capacity or greater are equippedwith two terminal blocks capable of acceptingup to 10-gauge wire.

Fuses

Per UL requirements, Indura units with batterycapacities greater than 20 AH have fused DCoutput.

Voltage Drop Tables

The following information is provided to assistin planning layouts for emergency lightingsystems. The National Electrical Code limitsvoltage drop to a maximum of 5 percent ofnominal. Thus, circuit runs must be of sufficientsize to maintain operating voltage when remotefixtures and/or exit signs are connected to theemergency lighting equipment. The table belowshows the length of wire run based on systemvoltage, wire gauge and total wattage on therun.

Formula: As per National Electrical Codestandards,

VD = 2 x L x I x R 1000

Where: L = length of run in feetI = currentR = resistance of material at 750CVD = voltage drop

Example 1:A 12-volt system using a 10-gauge wire willoperate four 12-watt lamps. Total watts on thewire run is 48, length of run from table is 70feet.

Longer Wire RunsIf loads are uniformly spaced along circuit path(equal watts, equal distances), lengths in thetable can be increased by certain values.

Example 2:Remote heads from Example 1 will be uniformlyspaced. Multiplier is 1.6 for four fixtures.Maximum permissible length of wire run is 70'x 1.6 or 112'.

Number of fixtures 2 3 4 5

Multiplier 1.33 1.5 1.6 1.67

To determine multiplier for six or morefixtures, use the following formula:

Number of fixtures = n

Multiplier = 2n n+1

Standard Control Panel

A status LED and test switch are provided on allunits. To begin a test, press the test switch andthe lamps will come on. The status LEDindicates that the AC power is applied and theunit is charging. The color of the status LEDindicates the charging state of the unit.

Self-Diagnostics(Available with the Select, Premium and Ultimate Option Packages)

The NFPA 101 - Life Safety Code requiresemergency lighting to be tested for 30 secondsevery 30 days and 90 minutes once a year.While the annual test has to be manual, themonthly test is allowed to be an electronic self-test (a monthly visual inspection is stillrequired).

One benefit of the automatic test is lowermaintenance cost because maintenancepersonnel no longer need to use ladders andlifts to manually test the units on a monthlybasis. Only units that indicate a failure willneed to be inspected. A second benefit isgreater performance and reliability of the unitsbecause manual testing is rarely performed.Self-diagnostics assures that units are testedand problems are identified.

Control Panel

Manual TestTo manually test, press the test button, lampswill come on and a 30-second diagnostic testwill start. The status LED indicates the unitscharging state if diagnostic failures are notdetected during the test.

Note: Unit must have adequate charge level to run test. If the unitindicates inadequate charge when the test button is pressed, the unitwill need to be charged longer before a manual test can beperformed.

Remote Test(Available with the Extra Option Package)

When remote test is ordered, the unit isequipped with a radio frequency receiver thatis designed to activate a 30-second test from upto 35 feet away with the use of the hand-heldremote transmitter (ELA RTT). This eliminatestime spent climbing ladders or riding lifts totest equipment. The ELA RTT must be orderedas a separate accessory. A minimum of one perjob location is required.

ELA RTT

Self-Test ScheduleThe unit automatically performs a five-minuteself-diagnostic test every 30 days. The unit alsoautomatically performs a 30-minute self-diagnostic test every six months.

Self-Test ReschedulingIf a self-test occurs at a time when it is desiredthat the lamps not be on, the automatic self-test can be delayed for eight hours by pressingthe test switch once during the self-test.

Automatic Load Learning FeatureAll self-diagnostic units are capable ofautomatically determining the total connectedlamp current during the first scheduled self-test. After the unit saves this information, alamp failure will be indicated anytime a greaterthan 10 percent reduction in total load currentis detected.

The load learn function can also be initiatedmanually by pressing and holding the testswitch for 15 seconds, during this period thelamps will be on. The unit will signal that thetotal lamp current has been saved by turningoff the lamps at the end of the 15 secondperiod. This manual load learn feature shouldbe used whenever the total connected lampload to the unit is changed.

Note: Manual load learn functions will not function if there isinadequate charge on the battery. If this is the case, wait until thebattery enters trickle charge mode and then initiate manual loadlearn function.

Clearing Failure IndicationsOnce the failed component has been replaced,press the test button once to clear the failureindication.

NEMA 4XNow available with a NEMA 4X rating, Indura4X provides protection against falling dirt, rain,sleet, snow, windblown dust, splashing water,hose-directed water, corrosion, and the damagecaused by the external formation of ice on theenclosure.

What is NEMA 4X?NEMA is an organization responsible for settingenclosure standards. UL has adopted thesestandards; thus the term "NEMA 4X." ULprovides a UL50, 4 and 4X listing based on theproduct passing the below tests:

1. Hosedown test - a 1" diameter hose delivers65 gallons of water per minute at a distance of10-12 feet.2. Corrosion resistance - the product itself issubjected to a salt spray for 200 hours.3. Icing Test - the product is put in tempera-tures of -6.70C and sprayed down, thus causingice to develop on the lens and housing. Productis acceptable if while ice laden, the product isoperable and remains undamaged.4. Gasket test - gasket must maintain strength ofnot less than 75% when subjected to circulatingair in a temperature of 69-700C.

Cooler Temperatures LowerDischarge CapacityLead-calcium batteries are designed for drylocations with temperature ranges from 60°-90°F. Since the battery is the main temperature-sensitive element and many industrial environ-ments experience varying temperature ranges,it is important to know the effects on battery lifeand capacity.

Lead-calcium batteries operate on a electro-chemical reaction, which converts chemicalenergy to electric energy. The electrochemicalreaction is reduced as the temperature lowers.Thus, the available discharge capacity in abattery is reduced at lower temperatures.

Hotter Temperatures ReduceBattery Life, Not CapacityWhile lower temperatures reduce capacity withno adverse effect on battery life, warmertemperatures have no adverse effect oncapacity, but they do diminish battery life. Thelife of standard lead-calcium batteries is greatlyreduced when temperatures are consistentlyabove 900F.

The Indura Premium Option package utilizes ahigh-performance nickel-cadmium battery orhigh ambient lead-calcium battery especiallydesigned for environments with extremefluctuation in temperature. The Premiumoption is UL listed from 32oF (0oC) to 131oF(55oC). While battery life is still affected athigher temperatures, a good battery life can stillbe achieved with these batteries. The followingchart reflects battery life at given temperaturesassuming exposure to this temperature 24hours a day, 7 days a week and 365 days a year.

Environmental Conditions Options

Exposure to a given temperature 24/7/365 is extremely unlikely for an unconditioned space.Unconditioned facilities generally experience the same temperature fluctuations as outdoorapplications, except tempered to the warm side to varying degrees, depending on the ventilation of thefacility and the height inside the facility at which the temperature is being measured. Below areexamples of how to calculate the life of the high temperature batteries, depending on the amount oftime during a year that it is exposed to a given temperature. For each application, it is important toobtain the average temperature for each season of the year and measure the temperature variation atthe desired mounting height of the fixture to be able to apply these calculations.

Example 1: The average temperature during six months of the year (May-October) from 8 a.m. - 8 p.m. in a warehouse is 1300F (550C). At thistemperature, the life expectancy would be 1.6 years. The average evening temperature in these same months in the same warehouse application from8:01 p.m. - 7:59 a.m. is 860F (300C). At this temperature, the life expectancy would be 9 years. For the months of November through April duringdaytime hours, the average temperature is 750F (250C) in the warehouse. The life expectancy at this temperature would be 13 years. While in theevening, the average temperature is 500F (100C) and the life expectancy is 13 years. If we look at an entire year, it is 1300F for 25% of the time, 860F foranother 25% of the year, 750F for another 25% and 500F for the remaining 25%. If we average out the life expectancy for each quarter, this will give us atotal life expectancy of 9.15 years.

Time Delay(Available with all Option Packages)

HID fixtures normally require a time period of5 to 20 minutes to re-strike after momentarypower interruptions or brownouts significantenough to cause the HID lamp to lose its arc.Therefore, it is necessary to light the path ofegress during the re-strike time period. Thismay be especially critical in areas thatexperience frequent power interruptions orbrownouts. The time delay option meets thisrequirement by maintaining emergencyoperation for an additional 20 minutes afternormal power is restored.

Other possible solutions to this application areto order the HID fixtures with a QRS (QuartzRe-Strike System) option or QRSTD option.The QRS option automatically switches the120-volt quartz lamp on if there is a powerinterruption or brownout significant enough tocause the HID lamp to drop out. The 120-voltquartz lamp stays on until the HID fixture re-strikes. QRS does not energize during cold startof HID luminaires. Wiring for the quartz lampis internal to the ballast assembly; the 120 voltsrequired to operate the quartz lamp is suppliedby the ballast. Wattage of the quartz lamp(supplied by others) should not exceed that ofthe HID source.

The QRSTD option functions the same as theQRS, except for the quartz lamp whichenergizes under hot and cold startingconditions. The quartz lamp will come onwhen a luminaire is energized and will remainon for two minutes after start-up or re-strike.

Both the QRS and QRSTD options aresignificantly more expensive than the TDoption, especially when you add in the price ofthe quartz lamp. However, depending on theillumination requirements, the fixture, and thefixture mounting height requirements, it ispossible that the QRS option would berequired. Evaluate each particular job todetermine which option provides the bestperformance.

Note: QRS does not provide emergency illumination in the case ofa power failure.
