Id was/is clever but basic and doesn't handle any interference. It not data as such In 100ms the panel would pulse between 2.85v to 6.5v 1 pulse for biscuit 1 10 pulses for biscuit 10 and so on. Each biscuit counts the pulses and draws a different current if open or closed after its pulse count has occured After all 30 have done this the panel rises the line to 11.25v which resets the counters and tells the biscuits to start counting again. All in 100ms. If a biscuit reports open for 3 scans (300ms) the panel then reports alarm. Later panel had this programmable though You can imagine how any sort of interference would cock up this scanning

No its way different. Old ID was designed for very short cable on relatively big cables. It was for cars. It was then given to us in bigger lengths. Hkc use a completely different system but it's limited to 10 addresses on a single core. Mixing it on cores is not supported but I've done it on old ID systems I have

Upload a pic of the panel and detector so we can which colours are being used

there are many topics on apps and free vs charged. Nothing is free and usually free stuff tends not be much use

agreed but the market demands this doorbell height nickable tech. Ive already been asked to use the alarm to protect it after its nicked. Issue I have is that people think its better than an IAS then the low level 'security system' is stolen before it can upload anything now its the IAS problem to solve. Just have decent cctv that doesnt wait till the perp presses a button (that has to be in easy reach) or just have a door bell. Few nicked the old friedland bell push

i assumed they had pulled them all

I have used the takex pir externally with success not for alarms as such but for alerts At home I also use takex external 12m pet tolerant pir ms-12te

Thanks I love historic stuff, that's all proper interesting. But most is British by the looks

So to summarise all adt systems need a kill code, this code will only be used at end of support? Burglars can't wait for that, look for a tired, non maintained bell, break-in then enter this kill code. What a superb idea all we need is some kind of sign on the outside Oh wait does this mean anyone with an adt bell outside could use a code to......

Agreed, you own the equipment. You can do with it as you wish. Using your car theory you have paid all the payments and now own it. If you want anyone to work on your car its not going to be for free.

eol resistors are in the wrong place and is non complaint. If its wired with a tamper loop and be looking at that first

and you definetly dont have a tamper issue?

Hi there

sounds like high res then. Whats the loop resistance of the circuit. Im assuming its double pole. You shouldnt have 16 of anything on 1 circuit tho

its a gross attack. your panel will report that its different to a pulse attack. Basically means 1 big impact rather than a few smaller ones but depends how you have it wired if you have a contact in series with the shock sensor or did you bang the window to open it?

It's a switched mode psu I'd check it still has output with load. Unplugged even if knackered it will give voltage, check it on load

Be cautious though as you said they only do ooh to contracts only. I'd agree with that. But if you have no contract you also have insurance issues

Hello there

Best of luck, what did you do before?

On a bell the tamper isn't a switch it should be 0v if the tamper is ok Meter between tr and ho + you should get >12v

Agreed on the above a well maintained system should not activate the external bell however it should inform 'a level 2 user' that it has an issue. As pj says all those alarms that activate externally show that they are not looked after, maintained or bothered about. So never armed if functioning at all. Never let your external sounder activate without decent cause or some might think its just a power failure

To be fair they have a point.

imo you want to avoid network for the core system. It should function on its own routers need power etc so i wouldnt worry about the network side, just use it for notification etc
