Security for Remote Places
« on: April 01, 2007, 02:16:24 PM »

As most of the regulars know I have a place totally off the grid running on solar and wind,
this is to be a retirement place (hopefully) ;)
After setting up my electrical I soon discover that my x10 gear was useless running a modified sine wave inverter! Pure sine wave inverters are expensive(especially large ones)
I thought my hopes of protecting this remote place were gone until I found this Post: 6-watt security system to run off your battery, bank, or powerpack
After reading it I realized this was possible! ;) :D ;D
I ordered my unit right away! Not wanting to damage the unit with the modified sinewave, I wired a 9v Wallwart to the unit.
Motion sensors ,Door/Window sensors all work fine as they send the information to the unit RF
My unit dials out and informs me of any intrusion and resets, Of coarse I'm limited to not having any extra sirens or lights turning on/off but I'm working on that! ;) :D ;D
A true sine wave inverter is on my wish list but a security system no longer is!
A true test will be if I ever have a break in and hopefully that never happens!

Great work around Tuice and I hope you never have to find out if it works or not. True sine wave inverters are expensive but with any luck as technology marches on so will the dropping in price.

Well it works but Not sure if it will deter a thief, If not I've rigged up a wired cam (embedded into the logs) and a VCR Commander so I will know who they are and they won't get away with it!(for long) ;) :D
The siren will mask the sound of the VCR Commander coming on if they get any farther into the home! ;)

Interesting discovery by wctadmin!

I'm amazied on how much functionality remains WITHOUT 120VAC. The fact that it resets after 4 minutes and then REARMS is great!

I re-read the article (and follow-up posts), but I didn't see what wctadmin was plugging the GE Converter into. ???

But thinking (out loud) about rechargeable batteries (at 1.2VDC per cell - burned into my brain) and solar cells (which I have NOT researched), given that the control center works so well at 9VDC and minimum current draw, what is the feasibility of assembling a 9VDC Gel Cell and constantly trickle charging it via a solar cell pack? 8)

wctadmin was plugging the GE Converter into a 12 volt system.
he is slowly moving to low power devices to run off a solar 12 volt system.

A typical 9 volt battery will power the unit for 12 hours according to the manual(less I assume if an alert is triggered) Just trickle charging a 9volt rechargeable would work as long as you didn't have any lengthy days without sun. ;) :D

Look again, Good Buddy! :o I wasn't talking about a 9VDC, 150mAh NiMh or NiCd, but a 9VDC, 10Ah Gel Cell! (Like the ones in your UPS. ;) IIRC, they're 12VDC @ 7Ah though. I *KNOW* that they also make 6VDC, but gotta SEARCH GOOGLE to see about 9VDC, or 3VDC. )

Yes I know, I haven't put a meter on mine yet to see what it uses during an alarm trigger.
 If that was the only thing running from it you probably wouldn't have a problem but with all solar stuff you need sufficient storage for those cloudy days! We can get 5 or more in a row up here! Usulay only during the winter months thought! ;) Just like to point out any draw backs one might en-cure. My system consists of 10 or 12(can never remember) 6 volt batteries @ 220ah each but then I'm running a house! ;)

I'll bet *THAT* could get a Craftsman wrench glowing! :o

What composition are they? Lead-Acid Deep-Cycle Marine?

Would you, or anyone else following this, know the range in Ah of available automobile batteries?

I was just roughly extrapolating out from what we already know (too lazy to build a 'pretty' table right now :P ):

  • 0150mAh: 012 hours
  • 0300mAh: 024 hours - 01 day(s)
  • 0600mAh: 048 hours - 02 day(s)
  • 1200mAh: 096 hours - 04 day(s)
  • 2400mAh: 192 hours - 08 day(s)
  • 4800mAh: 384 hours - 16 day(s)
  • 9600mAh: 768 hours - 32 day(s) on 9.6Ah


...you need sufficient storage for those cloudy days! We can get 5 or more in a row up here!

Yeah, so?? ???  How many cloudy days? ;)

Automobile batteries are rated differently although you could use one for this application they aren't meant to be discharged then recharged to the extent of a deep-cycle battery Most have the rating printed on the battery!

And that is without an alarm condition that just keeps the information in tack!
I'm not trying to shoot down your Idea if thats how it appears!
I don't know much about the small solar chargers other then they don't weather well!
It may be cheaper to trickle charge a 12volt battery and convert it to 9 similar to the way wctadmin has done ;) :D ;D

I don't have one handy here in my den - would you mind reading off the label on yours?  ;D

Naw, I'm not thinking you're shooting it down - I'm thinking you're not understanding it. ;)

My understanding is, supplying the correct voltage is always more efficient than regulating a higher voltage (i.e. heat equals wasted energy). So, strictly for the Security Console, I'm thinking a 9VDC @ 7Ah Sealed Gel Cell with one of those 'inexpensive' 12VDC Solar Cells that you can place on the dashboard of your car and plug into the cigarette lighter.

K.I.S.S. from an "Old Tinkerer" - that's all. 8)

I believe their is a site that breaks down a normal car batteries cranking amps into AH But for the price difference A deep cycle battery is the best .
I found this clip from Northern Arizona Wind & Sun
Starting, Marine, and Deep-Cycle Batteries
  • Starting (sometimes called SLI, for starting, lighting, ignition) batteries are commonly used to start and run engines. Engine starters need a very large starting current for a very short time. Starting batteries have a large number of thin plates for maximum surface area. The plates are composed of a Lead "sponge", similar in appearance to a very fine foam sponge. This gives a very large surface area, but if deep cycled, this sponge will quickly be consumed and fall to the bottom of the cells. Automotive batteries will generally fail after 30-150 deep cycles if deep cycled, while they may last for thousands of cycles in normal starting use (2-5% discharge).

  • Deep cycle batteries are designed to be discharged down as much as 80% time after time, and have much thicker plates. The major difference between a true deep cycle battery and others is that the plates are SOLID Lead plates - not sponge. Unfortunately, it is often impossible to tell what you are really buying in some of the discount stores or places that specialize in automotive batteries. The popular golf cart battery is generally a "semi" deep cycle - better than any starting battery, better than most marine, but not as good as a true deep cycle solid Lead plate, such the L-16 or industrial type. However, because the golf cart (T-105, US-2200, GC-4 etc) batteries are so common, they are usually quite economical for small to medium systems.

  • Many (most?) Marine batteries are usually actually a "hybrid", and fall between the starting and deep-cycle batteries, while a few (Rolls-Surrette and Concorde, for example) are true deep cycle. In the hybrid, the plates may be composed of Lead sponge, but it is coarser and heavier than that used in starting batteries. It is often hard to tell what you are getting in a "marine" battery, but most are a hybrid. "Hybrid" types should not be discharged more than 50%. Starting batteries are usually rated at "CCA", or cold cranking amps, or "MCA", Marine cranking amps - the same as "CA". Any battery with the capacity shown in CA or MCA may not be a true deep-cycle battery. It is sometimes hard to tell, as the terms marine and deep cycle are sometimes overused. CA and MCA ratings are at 32 degrees F, while CCA is at zero degree F. Unfortunately, the only positive way to tell with some batteries is to buy one and cut it open - not much of an option.

each size has a different rating it will be stated as cranking amps for a starting battery and Amp Hours on a deep cycle.
There are limitations to running the DS700 on 9 volts (you can't activate lights and no extra siren)
Although SmartHome does sell an extra weather resistant wired siren for their (Smarthome SecureLinc II Wireless Security) System I'm not sure if it will work with the PowerHouse PS561 ( that may be my next mod) ;) :D ;D

Update:
I had my sisters and their families up for a few days!
I have the system set to chime when a door /window is opened and that didn't seem to catch anyones attention.
latter that night while sitting around the fire place(was raining outside) the unit chimed!
 Almost every one asked "What is that?"
 I responded with "The security system is telling me someone left the door open!", as I got up and closed the sliding door.
Everyone was amazed,  I told them it would even phone me in the event of a break-in and allow me to listen in ,their eyes widened even more!
When I told them there was no monthly charge for that they were more amazed!
"Wow High tech features in a log home miles from nowhere" was one comment. ;D :D
This unit continues to bring a smile to my face as well as peace of mind! ;)

Very cool Tuicemen,
           This is kinda off topic. You had noted earlier that you use wind as well. My question is how much of your place does the solar run? And if you don't mind me asking. Your square footage? I live in Florida and have been thinking getting into solar. But so far Ive been hearing prices of 30 to 40 (to get off grid). I think 12 would be well worth it. The generator (whole house) Ive been looking at is around 9. But then you have to have a propane tank and then insurance goes up bla..bla..bla. Anyway any info you care to pass along on this issue would be appreciated. thanks

Sorry tinnman.... I know your question is to Tuicemen. Your post just caught my attention.

I lost power to my home 5 times the 1st summer we moved in, so I bought a back-up generator. That was nearly 6 years ago, and I haven't lost power since I got it. Now I see where Sam's Club (on-line) has a "back-up" solar system, I could use to replace the generator. Of course, the "back-up" solar system wouldn't replace the grid...... but it could shave down the electric useage.... as well as be there in an emergency.

No problem Dave,
              Thanks for the tip on the solar b/u from Sam's. I will have to look into that.
