It won't do anything to unsupported devices.
Thats just the answer I was hoping for. At least the 2 hour away one, I could remote reset it

Hi all,
As the heading suggests, the Government Alert test that will be happening this Sunday. Does anyone know or have any info on what it might do to GSM diallers, or do we sit tight and hope for the best? I personally own & run two units, one is here with me but the other is 2 hours away.
Cheers
Alistair

Lights are applications that don't matter too much for stability they are unlikely to be switched mode more dropper style circuits.
Computer PSU's need to be very stable but are much larger and more expensive. Neither can be compared for the application of an alarm.
A poorly designed SMPS will be noisy and have poor efficiency at a low load for example, linear is much simpler to get smooth supply in a small package.
Linear can also have a better life expectancy due to the lower complexity but that is unlikely to be a huge concern in modern electronics... if you get 10 years out of it.
As I understand it Elmdene make many of the SMPS on behalf of panel manufacturers and even they have had issues during the design process.
As much as copper has increased so have costs for other components and materials relative. You also may have to get your product you have been selling for years re-tested for sale in the market this all adds cost.
There are as always two sides to the story.
sixwheeledbeast, I totally agree with your reasoning, put like that makes sense. I can now stop wondering, and get some sleep!

They are simpler to manufacturer and integrate.
Many later models have switched
Just seems odd. Years ago, simple way of stepping down the mains voltage, but copper has become more and more expensive to produce and manipulate. China is knocking the switch modes out left right and centre on possibly a far cheaper scale. Its happened with Christmas light strings, used to be transformers, older computer psu's are all SMPS now. Alarm panel manufactures still sticking with transformers - must be because they have a very good life expectancy....
-
Hi all, just wondering why manufacturers still use transformers for the step down of AC to the panel instead of a SMPS that is as equally as powerful as a transformer, and possibly gives off less heat (product of inefficiency). There must be a reason, anyone know?

Well its odd, because my first alarm was a TS500, then I had a Melcom (looking back I should have gotten certified!!) Then next property a TS700 was fitted, then went onto a TS900+, the now, next property I put in a M800 and it was good, no problems. Then I went onto the current M2000. I have a SDGSM hooked onto it, outputs control lighting, also Atiny88's that use RF to control those Energenie mains sockets, all the christmas lights inside and out are controlled by them with the system timers. Only thing thats not controlled is the kettle! Its like sticking to your favourite car or van brand I suppose. You know how they work and more importantly how to fix them.

Ok just wondering, thought you might be using an old Nokia
I can tell your trying to tempt me with something ultra modern here al-yeti......... and I don't think your gonna make me crack....

neither, mines an A51 - does what I need without having to fork out £££'s. Its a phone at the end of the day, I have pc's at home and work, where I don't have to wince my eyes to read the screen and my sausage fingers can hit all the correct keys without getting them wrong

Fair enough, I may change one day when and if it packs in.

Yes
I would recommend upgrading panel and battery when you do it .....
Nah, I think I shall stick with the SLA, as its a lot safer or should I say less prone to getting warm and spewing sparks and smoke out. I have progressed from a TS700 years and years ago to my now M2000 which I really like - just wish it had more custom outputs because 8 just isn't enough for me. Do you still play with these al-yeti?

What does your panel manufacturer recommend?
Good point, as Menvier brought out the M2000 they did specify a sla, but in fairness that was recommended over 13 years ago - tech advances have moved on.

Hi all, Happy New Year to you all.
As the title suggests, what's the collective thought of these batteries from Ultramax? I have asked them if they are a direct replacement to the SLA type and they say they are indeed. Are they worth it, will they hold the system tight for much longer with mains failure than an 8 hour stint from SLA? As li-ion is the most unstable battery known to man, would you need to monitor its environment with regards to temperature triggering a zone maybe?
Look forward to your thoughts

Why do you need 22 contacts anyway? You only need to put them on external entries/exits, let the PIR's do their job.

Got an update for you, I think I may have got it....
Whenever I use downloader, I plug into the panel using an external USB socket ( so I dont have to keep removing the cover to make a simple change). However, if i did remove the cover, I would have to put my engineers password in, which would keep the panel silent (no lid tamper). So what I think has been happenenig is I connet to the panel whilst not in eng mode and the panel wont act upon timeswitch changes. So I entered eng mode, connected to panel via external USB, ran downloader and we've been fine ever since. I have also increased the time gap by 5 mins as al-yeti suggested.
I have two timeswitches set up. They trigger a Attiny85 IC that I have programmed via arduino, and it transmits the RF codes through the house and switches all my outside Christmas lights and internal ones via those Energenie wireless mains plug/sockets :o)
Many thanks for all your help, no doubt I will speak again soon.
Merry Christmas to you all

Hi al-yeti
No I haven't, that will be the first thing I will try tomorrow morning, could I ask why you would think that? I cannot work out, if you are after a timed pulsed output, why you need to specify an end (off) time to the time switch??????? All my relay outputs that are driven from my digi outputs have a diode reversed biased, like I say, I can force the output and the relay follows what I tell it to do, but the output doesnt always switch on when the timer actuates. Does the panel get it right 24 hrs later??
I should add for what its worth, the Panel Version is V3.11

I have the output set under System as this shows:
What I cannot understand is sometimes it work and sometimes it doesnt?????
-
Hi, firstly I should have said hello first of all - my sincere apologies.
Yes, I have setup the output to pulse and 1 second long. Sometimes this setup works, and a lot of the time it doesn't. If you have no problems, and you dont use downloader to do it, maybe its that then?

Evening all, can I ask if anyone has had any success with programming times witches with any M series Menviers???
I have an M800 and I am programming (through Downloader) time switch 1 - 1 to come on at say 20:00 and go off at 20:01, just to provide a 1 second pulse to drive a relay. Time switch 1 - 2 to come on at 20:30 and go off at 20:31, again to provide a 1 second pulse to the relay. All the days of the week for ON and OFF are checked. I can toggle the output to drive the relay through Downloader and its works everytime. Am I doing something wrong, and if I am, whet the hell is it please????

Yes its going to flag up a few problems I think. The one I never thought of is the secret phones that venerable people are using in abuse cases, once they start buzzing and reacting to a test message....
