Let’s Get GreenBack in the early 80s, energy prices were thought to

be on the verge of a steep and never-ending climb.

Economic gurus warned of future shortages of coal,

natural gas, and fuel oil. Thus, an entire industry was

born to attack energy waste, lest we run completely

out and be forced to usher in the next millennium

in a cold and dark world with no power.

As effective players in this new industry of energyconservation, building automation system (BAS)contractors can look back over the past 25 yearsand be proud. Innovation, engineering, and a lot of hard work by Kele’s customers not only helpedavert an energy crisis, but continue to lead theway to a sustainable environment for our future.

Today our systems are being incorporated intonearly every construction project, and the greatmajority of application mysteries have beensolved. Perhaps it’s time to devote a little of our industry’s considerable innovation and engineering talent to our own equipment. In other words, let’s have a look inward:

• In performing its energy-saving functions, how much energy does a typical BAS consume?

• How much of that energy could be saved with reasonable, cost-effective changes in the way we’ve always designed our systems?

This article is not an attempt to answer thesequestions in a definitive way – the examplesincluded are small, isolated parts of a complexproblem. Rather, this is an attempt to get us all thinking toward the future. Government regulations are already putting pressure on the consumer electronics industry to reduce parasitic energy consumption. It won’t be toomany more years before the pressure spreads to BAS designs, so it would benefit us all to have a head start in the thought process.continued on page 4

Think green – and always think of Kele for the widest relay selection in the industry from Idec, Omron, Magnecraft, and Functional Devices to eliminate wasted control power!

Green Controls: ProLet’s start with a look at control transformers and the peripheral devices to which they provide power.Unlike large utility transformers that have efficienciesgreater than 99 percent, transformers in sizes we use to power our BAS systems and their peripherals(40 to 500 VA) aren’t as efficient as one would think.Power converted to heat by these devices can rangefrom two to five percent of nameplate full-load watts– even with no load connected to the secondary –and can approach ten percent at full load.

We recently metered a 300 VA transformer that drewalmost 15 watts at no load. It serves to power a groupof controllers and actuators for condenser water mixingvalves. The facility has full-economizer air handlingsystems that only operate weekdays from 8 a.m. to 8 p.m. Thus, in a typical year this transformer is onlyon duty (chillers running) about 2,000 hours. The other6,760 hours per year, the controllers idly consumeenergy at a rate of 35 watts, and the transformerwindings (at 35-watt load) consume energy at a rateof 20 watts. Add in 10 watts’ worth of pilot lights,and total input power to the panel is 65 watts. At $0.08 per kWh, that’s $35 per year of electricity –certainly not a budget-busting amount. But that $35savings will easily pay the marginal cost of adding adigital output, to snuff power to controls when they’renot needed. And that $35 will keep being saved, year after year, for the life of the system.

How many installations can you think of in which control power is wasted for significant periods of time?How many VAV terminal unit controllers out there aredoing nothing, idly consuming power while the airhandler that feeds them is shut down for the night?How about big transformers that kick the mechanically-held lighting contactors on and off twice a day for a couple hundred milliseconds, then sit idle while generating waste heat for the other 23:59:59.8?

People who design battery-powered devices learnedlong ago that conservation is key to the success oftheir products. We in the BAS industry have beenspoiled by the ease with which we can grab controlpower capacity – and by the fact that nobody hasfocused in on the energy we routinely waste.

I had a boss back in those turbulent early 1980s who kept his office thermostat set on 65˚F (cooling in the hot Memphis summer) even though we wereadvising all of our clients to save energy or we wouldall be doomed. He claimed that, as the front-line warriors in the battle to save energy, we were exemptfrom the conscience of the public we were fighting to save. It sounds just as silly and embarrassing todayas it did back then. But aren’t we just a little less greenthan we should be, too, if we wire up transformersthat spend lots of their time doing nothing but creatingwaste heat and an unpleasant hum?

FIGURE 3: The Kele model 1.5KE56CA bi-directional Transzorb surge suppressor can be placed in parallel with the 24 VAC secondary wires at the first load connection downstream from the transformer.

spike that results from opening the primary. A secondoutput or a more expensive time-delay relay wouldbe needed to ensure coordination.

A less costly method of protection is one we shouldall know well by now. A Kele model 1.5KE56CA bi-directional Transzorb surge suppressor can beplaced in parallel with the 24 VAC secondary wiresat the first load connection downstream from the transformer (FIGURE 3).

FIGURE 2 shows how the Transzorb takes the top off the spike, dissipates the excess energy, andkeeps the voltage from reaching damaging levels.For larger transformers, multiple Transzorbs may beconnected in parallel to contain the spike’s energyand keep bouncing back for more. In our experience,one Transzorb per 100 VA of transformer nameplate capacity has proven to be more than adequate when primary switching occurs.

Green Controls: Consensus?The short answer is “no consensus yet.” Everyone agrees that minimizing wasted energy by reducing or eliminating unneeded operation of our BAS components is a goal to which we should all aspire. It probably won’t reach the mainstreamthough, until regulations are put in place throughrevisions to the energy codes. Now is the time tobegin devising reliable ways to do so – and we at Kele would like to hear about the innovative solutions that our customers create. Call KeleTechnical Sales today to discuss your applications.

Let’s Get Green from page 3

Let’s think about adding some controls to our controls.There is economic incentive, to boot – you’ll sell a fewmore relays (which you’ll of course buy from Kele) andyour customer will have a reduced electric bill. Everyonecomes out ahead but the electric company. So, let’s get green.

Green Controls: ConAfter presenting all of these good arguments to a panel of engineers, the first response from the anti group wentsomething like this: “Now, wait just a dadgum minute! Being green is all well and good, but if you’re planningto shut down the primary side of all those controltransformers on a regular basis, you’d better budget fornew controllers on a regular basis, too. Powering themup and down like that’ll kill ‘em, sure as I’m sittin’ here!”

After debate, all agreed that precautions must be taken if one intends to cycle power to control transformer primaries. It’s common knowledge that interrupting the primary current to a loaded transformer may havebad consequences. All of the energy stored in thetransformer’s magnetic field will zip down the wires to the only thing that will accept it – the load that isstill connected to the secondary. Electronic controllersand even some of the smaller relay coils may succumb if not properly protected.

FIGURE 1 shows a trace of such a secondary voltage spike at the instant the primary is opened with a smallload on a transformer. One sure-fire solution would beto include another relay to shut down the secondarypower first. The primary relay would then only be requiredto break the no-load current of the transformer, and nosensitive devices would be subjected to the voltage


Q: What, exactly, is allowed to be installed above a lay-in ceiling when that space is also used as a return-air plenum? I have an enclosure that is rated UL94V-0, is that good enough?

A: We could give you a many-page answer to that one, but the correct answer most often is, “Either ask the local inspector or find another place to mount that thing.” That’s based on experience and a strict interpretation of the 2005 NEC®, in which paragraph 300.22(C)(2) limits equipment to:“Electrical equipment with a metal enclosure, or with a non-metallic enclosure listed for the use and having adequate fire-resistant and low smoke-producing characteristics, and associated wiring material suitable for the ambient temperature…”

It’s that “…listed for the use…” part that makes nearly all combustible materials taboo in plenum applications. In order to be listed, UL requires combustible materials to meet some stringent requirements for heat and smoke release. The testing is described in several standards, including UL 723, ASTM E84, NFPA 255, and UL 2043. Passing all of the required tests and achieving listing for use in plenums is quite a feat. The UL94V-0 you cited is a vertical flame spread rating, which is a completely separate issue. It should not be considered permissible in plenums, but it often is accepted by local authorities.

The main reason we urge you to ask the local inspector (authority having jurisdiction, or AHJ as described in the codes), is that local codes have begun to adopt their own restrictions for equipment and wiring in plenums, over and above the requirements of UL and the NEC®.

A notable example is that the 2005 NEC® explicitly permits flexible metallic tubing or flexible metal conduit to be installed in above-ceiling return air plenums. But, you’ll pay dearly if you do so in Chicago without checking the local requirements first. There are special ratings for flexible metal conduit that were developed for the city of Chicago,and other municipalities are taking steps to adopt them or are considering doing so. It’s just too risky to spend money on anything questionable without asking! If you can mount the equipment elsewhere, then do so. If you can’t, get permission.

Q: I enjoyed your article in the last issue of Kele Insights regarding temperature sensor spotting. We’ve never taken the time to make a nice checklist like that, and we plan to make it a standard. Can you go one step further and give us a suggestion for those super-tough installations where there just isn’t any good spot on the wall? We’re still seeing architects hand us all-glass areas and clear-span areas that are way too big for a single zone.

A: There will always be challenges, won’t there? For those instances where wall mounting a temperature sensor is just out of the question, here are three Kele alternatives that have been proven in the field:

SHOPTALKQ&A From the Field

Products Shown: (left to right)

BAPI Wireless Room Temperature and Humidity Transmitter(Model BA/BS2-WT, Kele 2008 Catalog, page 505)

Yamatake Radiant Room Temperature Transmitter(Model TY7321A1009, Kele 2008 Catalog, page 799)

Kele KTV Series Duct Temperature Sensor (Model KTV3 shown in FIGURE 1, Kele 2008 Catalog, page 733)

• Kele Frontier or BAPI Wireless temperature sensors, battery-powered and ready to mount on furnishings if needed (folks use everything from Velcro® to Gorilla Glue® to stick them in place, depending on security needs). They’re in stock at Kele, too, for same-day shipping to help you when that tough application rears its ugly head at the last second. See pages 481 and 505 in your new 2008 Kele Catalog for ordering information.

• The Yamatake TY7321A1009 infrared radianttemperature transmitter can be mounted in a ceiling tile and its optics can then be directed at a surface that’s indicative of space temperature.These are also in stock at Kele. See page 799 in your 2008 Kele Catalog for more details.

• Finally, one of our favorites (thanks to Jean Haydel with Haydel Associates LLC, in River Ridge, LA) comes into play if the space supply air diffusers are of the common primary /room air induction type.Mount a Kele KTV duct sensor (see FIGURE 1)and you’ll get fast-responding temperature indication from well-mixed room air, with no influence from radiation (unless the sun can hit it directly, too). Mount the sensing tip of the KTV just five inches below ceiling level. It’s unobtrusive and just a dab of paint on the bolt heads to match the diffuser will keep the architect happy, too.

FIGURE 1: This diagram shows an installed Kele KTV3 duct temperature sensor, with the sensing tip extending below the ceiling level. The diagram also depicts the supply air flow and the induced room air flow to and from the ceiling diffuser.

Just use my simple, two-step door handing method to determine

the “outside” side of any door.

Let’s start with the two types of lock configuration you'll encounter –mortise and cylindrical. In carpentry, a mortise is a cavity that’sbeen chiseled or routed into the edge of a piece of wood. Mortiselocks are generally rectangular in shape and they slide into justsuch a cavity in the edge of a door that is opposite the edge withthe hinges (the strike side). If you have a steel security door on theentry door to your home, it probably has a mortise lock. You’ll findthem on most metal-frame glass doors and commercial businessdoors as well.

Cylindrical locks on the other hand, are inserted into a cylindricalhole that is bored through the door near the strike side. You’reprobably more familiar with these, since they’re almost alwaysused with wooden residential doors of all types.

Open Up!More of your customers are going to ask you to integrate physical security

with the BAS systems you’ve been providing them for so long. It’s important

then, to become familiar with some terms from the somewhat arcane world

of the locksmith. Why? Your customers will be asking you to automate the

action of securing their doors and you’ll need to describe locking scenarios

to a Kele Sales Associate in order to get the right parts.

Fundamental Fred Unlocks the Basics of Doors and Locks


Now that you know these mostly-universal terms, you’re on your way to being able to describe a locksetto someone over the phone. Combine these with yourknowledge of door handing (see Fred’s method in thesidebar right) and you’ll be ready to select and order theSecurity Door Controls electric cylindrical or mortiselockset you need from Kele. Of course, we’ll be glad to help! When replacing existing locks, Kele TechnicalSales folks are used to receiving digital photos by e-mail.Call us – we’ll be glad to help you find the perfect lock.

“Whaddaya mean is my door

left handed or right handed?

It doesn’t have hands, it’s a door ...

oh, you mean which side of the door has

the hinges? That depends on whether

you’re standing inside or outside.

Wait a minute, Fundamental Fred

has the key to help you out.”

Fundamental Fred’s Simple Two-Step

Door Handing MethodDetermine which side of the door is “outside.”– For exterior doors, outside is literally outside.– For room doors, outside is the hallway side.– For simple communicating doors (like from one

hall to another), outside is the side from which the hinges are not visible when the door’s closed.

– If it’s a closet or storage room door, outside is the hall or room to which it is attached.

Choose from four possible handing options:

Both mortise and cylindrical locks can have a variety of configurations. The locking mechanismprotruding from the door into the jamb can be alatch, a deadlatch or a deadbolt. Depending uponsecurity needs, a door may have more than onetype of mechanism. Briefly, a latch is a simple,spring-held piece of metal that is sloped on oneside in order to depress itself into the door as itslides across the strike plate. It then falls into thebored (or mortised) latch hole (sometimes called a keeper) in the door jamb. It’s not a very securedevice. Unguarded simple latches can often easilybe depressed back into the door while it’s shut,with a knife, a small screwdriver, or (as JoeMannix taught us long ago) a credit card.

A deadlatch, in addition to a sloped latch, contains a second, spring-loaded metal pin that abuts the non-sloped edge of the latch. This second piece isdesigned and installed so that it does not fall into the keeper hole in the door jamb when the door is completely shut. When the latch is in the keeperand the deadlatch pin is not, the latch cannot beforced back into the door. It’s a much more secureset-up. However, a trickier-than-average thief canoften still find ways to defeat the deadlatch.

Finally, a deadbolt has a non-spring-loaded metal rod (the bolt) that must be manually pushed into adeadbolt hole in a door jamb in order to secure thedoor. At the end of its travel, a pawl engages the boltand prevents it from being forced back into the door.
