so its not about cheap, ill exclude the Samsung for now you want good?

what do you drive and what phone do you have?

can I ask a trivial question?

you cant compare the 2. look into wireless security on your 2 systems. but if you want cheap then security and reliability are not top 5 on your list of requirements

or use a panel that knows its been attacked and will fire the bell if the panel is removed

if someone was to force the front door and take out the panel just there in the hallway during entry time then what?

could be a faulty device but id also suspect cable. Test with your meter

intruder is a different output type. Program it as bells from what you have said.

unless your testing resistors then 200 ohms is the setting it should be in

yes if you want to move. assuming its not rented

depends is it a subsidised install cost? there will be a minimum term. some are 12 months some 3 years etc

no the piezos run at high voltage. what happens if you disconnect the battery on the sab that is misbehaving?

I really cant see that can be happening on ac fail if its wired like that Can you replicate it?

I wouldn't do that. I can't see how it can be the bell box. Can you post photos of how they are wired?

It may do but the power from that bell is either coming from somewhere other than the main panel or it is wired of another output. What panel is it?

I dont think that any of those are issues with yourbell. DO you have another power supply etc?

yes

op I was trying to show your theory that all is the same was a folly. You obviously know better and I'm wrong. Sorry I said anything that you don't agree with. Btw how did your a.n.other 868 work?

I want to use a ford key on my Audi, cant see why it won't work.....

yes it will. The more current you pull the more the volts will drop. No current = no vd. If you pull a load then you need to think about it

a. Ideally 13.69 but that is now 13.75 as most diag cant hit that resolution b. Ohms law depends on the resistance and the distance. Resistivity is what matters. If the course is up to date id assume you discussed copper vs cca

flush contacts I like these https://www.securitywarehouse.co.uk/catalog/elmdene-en3qfc-grade-3-flush-contact-green-resistors-p-1620.html

could you post pictures of the doors?

As above in old term its an SAB, sas or scb

before you throw away your meter is the battery ok in the meter itself. When they get low it causes them to over read
