Hardwired Lighting System Using Cat5

If anybody wants detailed pictures of the ALC modules (I have the ELK interface, ALC expansion, Distro module and the 'normal' hub) then let me know and i'll post some. The ALC documentation available from SETNET covers it it pretty well already.
 
When I wired, I figured I could use one run of cat5e to a lot of locations. For instance, a 3-gang box with 3 dimmers, 2 of which will need aux control will work fine. 2 conductors service the ALC network for all three switches in the box. That leaves 6 conductors, three for each aux-controlled switch.

Well, that's a good point. I think the only area I really have a problem is this gang of 3 switches. Even if they were all aux switches, that'd still be 9 wires.

Tony, are you sure that these aux switches can't share a common? They're just detecting the closed circuit, right?

They do not share a common. But I have not tried to share a common anyway. I'll get back to you after I share one...

Am I screwed??

I ran a single cat5 to several switches, everywhere. And then I homeran everything. I didn't run any wires from switch to switch for auxillaries, as I figured I could do that down in the basement.

Because auxillary switches are also punched down in the branch hub, I thought that the aux was affecting the switch via controller commands. In other words, that I WOULDN'T have to connect the aux wires from the master switch, just the + and - wires.

Now looking at the diagrams again, am I seeing it correctly that being connected on the branch hub does nothing more special than just make the same physical connection as if the aux was wired directly to the switch?

So in other words, each aux-controlled switch requires a full 5 of the 8 cat5 wires. So a single cat5 cable will not be able to serve 2 switches that also have aux controllers (3 or 4-way).

if so...then I am totally screwed. Or at the very least, GREATLY screwed.

:)

AceCannon is right on target.

Aux switches are brainless. You do not provide power to them and as such, they are dry contact closure devices only. So... no +, no - just 3 wires for the on/off
Aux switches are dry contact closures (2 per aux). This takes one wire for on, one for off and these two share a common (2 aux switches do not share commons).
Aux swithces have no ALC address and as such need no polling loop communications.
You can link an ALC aux with it's addressed ALC switch by running wires between the two (3 conductors). Or by connecting them back at the panel or on a hub.
Although we promote a homerun for every single switch (now you know why), you can "Daisy Chain" up to 31 distinct ALC addressable switches (not Auxes) on the same cable run. This would take a total of 2 conductors leaving 6 conductors for use with 1 aux switch.
Why one??????? It's because in the case of a Daisy Chain loop you will need 3 conductors from the aux and 3 conductors from the matching addressable switch. So...... daisy Chaining is not the way to go. So, the correct way to wire a aux is....
Run a 3 conductor (most people use cat5) from the aux to the matching addressable ALC. Or run a 3 conductor to the panel or to a hub.

And yes, the branch hub just provides a neat place to connect your aux, it does nothing else to the aux at all.

This thread is quite long and as such many details and discussions are lost in the past. But each ALC comes with instructions. Better yet, feel free to call and let's talk. 864-663-0011

Ughh :-( I hate to be the bearer of bad news.. And Tony can confirm.. But I think you are right.. I am pretty sure, almost positive, that you need 5 wires for a 3 or 4 way switch for the actual switch ;)

I think that was discussed earlier in this thread - or maybe I read it in the OnQ docs :-(

Are you able to pull more cat5 to any of these locations?

Three wires. On/Off/Common (no power, no polling loop communications).

Well, damage control is beginning.

The worst spot is by the front door, which currently has 3 switches in it, 2 are 3-way, 1 is 4-way. Even if I put all AUX switches there and found room for the main switch in another box, that'd still require 9 wires for all the auxs.

*sigh*

With all the mayhem of construction and wiring, I just figured I'd take care of wiring the auxs down in the basement later. I didn't want to have to decide where the main went and where the auxs went (which you'd have to decide if you were to wire them directly). I just figured since the auxs were also wired into the branch panel that they could control the light directly through the ALC controller, instead of from the switch itself. Of course (now) that doesn't make sense, since those auxs wouldn't work if the controller was down then...which we know they do. I just didn't do enough investigation I guess.

The wire for the front door box comes from directly below in the basement, so there's a chance of adding a wire. I think I can make all the other boxes work with some thought about arranging where the main and aux switches go.

:)

I am sure it isn't optimal.. And I am not sure the hardware needed but I would think you could get a device to detect a dry contact and with that and elk or CQC control the switch. Tony says not to use the elk directly because its measurement time for contact is slower than a standard button press. However, I would think someone has made a board that will not dry contacts, and open an output which you could feed into the elk.

If you can learn to press the button and hold it in a little longer than normal (a bump don't register) then you can still use the Elk M1 to read dry contact closures from an aux or any contact closure scene/mode switch.

However in the issue of solving the problem of not running enough conductors, you still need to install an add-on scene switch and run it's cable. So, you may not be much better off.

I will ask Spanky at Elk to think about letting each zone have an adjustable response time. Then you can speed up the response time of scene swtich contact closures whiel keeping alarm zones slower. Maybe they can add this in an upcoming firmware release.

Your front door would have been a great place for a quad aux. It would have needed to be in a single gang box of it's on, but would have reduced the total number of light switch "acne" points in that location.

beelzerob:

sorry to hear about your situation...hopefully it won't be too painfull to run the extra wiring.

My install will start this weekend...hopefully i wont have a similar OOPS.....at least we can all learn from each other...

See my smaller OOPS below...i suspect many will be running into this.



I finally came home from my business trip and found all the ALC stuff that was shipped. Due to time difference it is now 4am and i am in the basement trying to put this stuff into the structured wiring panel.

To others:
THE ALC MODULES INTENTED FOR STRUCTURED WIRING PANELS DO NOT FIT IN A LEVITON SMC!!!!

They have 2 tabs on the left and the little punch tinghy on the right, but the thingy on the right is vertically halfway between the 2 on the left whereas a Leviton SMC has horizontal rows of buttons. I suspect this means it wont fit in a Channelvision either. I havent seen Legrand structured wiring panels, but their hole pattern must be different the Leviton/Channelvision.

I am contemplating 2 solutions:
- remove the ALC modules from the mounting plates they came with and get some ELK mounting plates (SWP3) and transfer them to that. Physically they would appear to fit, but it would require drilling of holes into the ELK SWP3. Removing the ALC modules from their mouting plate looks doable but a pain (lots of individual screws).
- drill new holes into the Leviton SMC where they are needed. The tabs on the left side of the ALC modules are also slightly too big to fit into the SMC holes, so one would have to drill out the holes anyway...I plan to drill 2 new holes for the left tabs rather than for the right pushpin. This way all the original holes in the SMC stay the correct size and if i ever reconfigure the original holes can still be used.

How have others dealt with this?

On the upsite and slightly OT ...the 8811 protocol adapter from Aprilaire initially appear to be surface mount only, but if you put SMC pushpins where the screw are supposed to go then it goes into the SMC easyilly. The 8811 that i received doesnt look like the picture on the various websites though and does have the 2 RJ45 connections i was hoping for. For those that have one...what does your 8811 look like? I was expecting the red box. Maybe SETNET has the wrong picture up?

FYI
The Structured Wiring Industry has two schools of thought for enclosures. Many brands (OnQ, Open House, Strcutured cabling Products and quite a few other) use 6" on center mounting. This approach appears to be the standard if such a thing exists. The other manufacturers tend to stay on the proprietary side with little industry wide compatibility.

As for mounting don't overlook the double sided tape from Elk - Part number elk-999.

As for the 8811, it could be the wrong pic. I will contact Aprilaire Monday for a new one.

And by the way... Welcome home....

Tony (and others):

When you don't have any Aux's connected to a dimmer, what do you do with the black/red/green? Do you tape them? Cut them?

Since they come pre-stripped leaving them out in the open would probably spell trouble....if you cut them would you still need to tape them?

Started my first ALC install today. Replaced a set of 3 toggled with 3 dimmers (no auxes involved). All the HV is done and no sparks anywhere..so all good. 3 dimmers in a box does make for a LOT of wires in there since the ALC dimmer don't have terminals on them. ;)

Any bare LV wires that are free to "float" inside the box could touch the insides of an AC HV wirenut in which case you would let the smoke out of any LV device. This is why the code calls for 1/4" seperation. So, keep the seperation and also insulate all bare connections.

Of the last 400+ ALC switches I myself have installed over the last 12 months, I have yet to find a bad one. The real enemy to an ALC switch is improper hookup. I have seen a number of times that the Electrician let bare LV wires touch HV while the HV was turned on and I have also seen Electricians wire nut the tiny LV wires to the Large HV wires thinking that they were HV??????

I just had a Technician (not an Electrician) return 13 ALC switches from an install of 105 total. He stated all were bad. Before we contacted OnQ, we put them on our bench for testing and found ALL of them to be working perfectly. So...... Poor troubleshooting techniques also result in product being condemed as bad.

And even if your AUX wires never come in contact with the HV...all they have to do is make contact with each other, and you'll be getting really fun and annoying on/off/dims going on. I noticed that several times while making the LV connections with the light on, suddenly it would start dimming and go to off. Sometimes I swear I wasn't actually touching the wires, but it made a connection somehow.

All of my ALC switches and auxs all work great. However, one of the first dimmers I ever got had a rattle in it. Not feeling good about that, I took it apart. I'm not exactly sure what it was that was loose in there...but in the process, some of the plastic that held one of the 4 front screws in came off. so, the front of the switch is held in place with only 3 of the 4 screws now....I'm not concerned.

Oh, and it's true...there ARE no use serviceable parts in there. :)

I have also seen the LV wires (the aux wires) get pinched against the metal chassis of the switch. This too will make unpredictable things happen with lights dimming/on/off etc. or even make them "lock" into off or on. And in some occassions, the + LV wire for the polling loop can smoke the switch if shorted to chassis ground. So while handling the switch wiring hot (both HV and LV) take care to avoid these things.

Tony, what is the size of the 12v wall warts for both the Elk module, and the expansion module (1A, 1.5A, etc.)? I have a ton of wall warts that got mixed up when I moved, and am not sure which ones to use for these modules.

Elk silk screens the required voltages onto their circuit boards. And in the case of DC supplies, they even silk screen whether the center pin is positive or negative.

But they do not put the amperages.

The Elk-m1 board uses a 16 volts AC 40 VoltAmp supply. I suggest staying with Elk for this as their supply has short circuit protection and a status LED. It's part number is Elk-TRG1640.

Most of the other interfaces can get their power from the main board supply. However the M1-XEP Ethernet interface has it's own supply.
It is a 12VDC, Center pin Positive. The XEP manual says it uses 300MA.

Hope this helps.

Good information, but I was actually looking for the power supply specs for the OnQ modules for ALC lighting. The ALC-Elk controller module, and the OnQ ALC distribution module, both have power supply connections, but I am unclear on what wall warts ot use with those.
 
I actually have the ELK<> ALC interface running without it's associated power supply. It seems to get it's power from the ELK databus hub. I was a bit surprised when the lights came on without the barrel connector in.

So what is the verdict on the unused LV wires? Cut the stripped part of, individually wrap then and then wrap them together and stick then 'on top of the box' behind the sheetrock with the used wires?
