Sounds like you may have been too late with the battery replacement, down power power up mains first then battery, but be warned that may get the panel back up and working (if you are lucky) it doesnt mean that the panel is okay. If the battery has been dead for a while then its likely to have done irreparable damage to the charging circuit

QFA Bus detectors or ID detectors from a different brand will not work

AM used to install them but the plastic on them was so thin it used to expand when the sun was on it and cause tamper faults, I told Pyronix but they denied there was a problem.

The only solid state smoke ive come across is when you accidently put the wrong voltage in something. This generally lets the smoke out of it. Ive found that its the smoke that makes electronic stuff work, because once you have let all the smoke out of a component it never works again.

Good luck with trying to get a panel from somewhere though, Ive been waiting months for a Dimension G3 panel and the last update was for an ETA Oct 9. If we were installing Galaxy full time we would go bust. Welcome to the forum

To be fair I have seen false alarms from the sun on glass coffee tables, mirrors on walls, pictures on walls, and this has been regardless of where the detector is facing. Id agree that Fa's the same time everyday is most likely sun this time of year, but I would be surprised if it was direct through the door. Its unusual for the sun to go directly into a detector through a window the sun is usually higher than the window and beaming down not up. Many of the detectors in my offices are facing the window and they are standard honeywell pir not even quad, (they were here when we moved in we just replaced the panel) and we have never a problem with them. You could say thats because we are open everyday, but not weekends bank holidays, we were even closed for a whole week during the pandemic and we never had a FA. Im not saying it cant happen and I respect your opinion SWB, I think its rare and although you saying a quad is a workaround, I say its technology designed not to FA when the sun reflects into it. Having a detector opposite a window also provides a visual deterrent to anyone looking in

Well done, its something your employer should be doing, its good to see that you are motivated to do it yourself though. Maybe you should be looking for a proper apprenticeship with a company that does more than just wireless tat

Before this topic gets any further out of hand: OP you have obviously done some sort of research on this subject or you work in insurance or worse you work for the MoD (Though I doubt its the latter as you would not be using Texecom) Most people think that using G3 components is some how better than using G2 in the same respect that £30.00 is better than £20.00, and in theory you would be correct. However, its horses for courses, you have to look at the complete picture. For example a MoD site holds secrets and designs of equipment that they would not want foreign spys to get their hands on. Spys will try lots of things including bribing or blackmailing, and this means the alarm has to be setup in a way that even the alarm engineer that installed it cant get around it, let alone the people that work there, its a similar story for banks and high class jewellers. The difference between a G3 system is not that it is necessarily any more secure, what it is is more sensitive. Door contacts have to be aligned correctly, detectors have to be positioned so that they cannot be accidentally masked ect ect. There are rules to installing a G3 system and a diy system using G3 components will never be a G3 system it will be a DIY system with lots of headaches. If you asked one of us to take it over I would so no thanks and I am sure most decent approved co's here would say the same, theres a reason that we are not desperate to get any contract at any cost. When an approved installer comes to survey he will carry out a risk assessment, this ra takes into account theft attractive property, how easy it is to break in (flat roofs ground floor ect ect), crime history of the area, what the insurer requires, and a few other factors. This assessment determines the grade of the alarm system, the type of monitoring required, in order to be a G3 system it has to be connected to a monitoring station with G3 or above monitoring equipment. You came here for advice. We have no idea of the contents of your flat or the likelihood of you being burgled, it looks a nice flat from the layout so I would say probably reasonable. I do understand why you want to do it yourself and I dont think that your trying to save money (if you are you are more foolish than I give you credit for). If you still really think you need g3 then my suggestion is that you get three quotes from NSI gold companies they will advise you professionally of what you need, and dont be surprised if they suggest G2 quads and point them at the windows. Since the invention of white light filters on lenses in 1992 I have been successfully pointing quad detectors at windows with no adverse effects. Our false alarm rate is less than 2% 100% of that is customer error and we have around 3,500 contracts, SWB may disagree with me on that one but he wont install wireless either.

Hi and Welcome

Not sure what your point is but if you turn the MW down to the minimum it will see 5 metres (again regardless of walls floors or ceilings)

If the DT says it will see 15 metres thats how far it sees regardless of walls thats how RADAR Doppler works.

My point is if you use PIR instead of DT you can point them at the windows and they wont fa if someone walks past but will pick up an intruder much quicker. I dont understand why you are installing G3 kit either

Exactly what I would recomend, why install DTs its not needed its like using a tractor for your daily commute. It will get you there but slowly The op is already thinking his concrete walls are 15 metres thick, and mw wont see through them

MW will see through the windows and walls the PIR wont

We'll have to agree to disagree there is absolutely no advantages to fit DT's in a dwelling. Especially so in a flat. Definitely not trolling, it is something I would not do, without good reason.

What floor are you on? It looks a nice flat layout I guess the value of the contents are high as you are going a little ott on a diy project.

I would swerve the G3 contacts too, G3 is not necessarily any more secure but they are far more sensitive and will give you more trouble especially with metal doors that can become magnetised over time

Id point the detectors at the windows rather than away from. They will activate much quicker when someone comes in. Dual techs are not a good idea for domestics they are designed for hostile areas. These detectors normally come with a standard pir which are not as good as a decent quad element. The thought is they dont need a decent pir because the use a dual detection system. but because the microwave will see through walls ceilings and floors if not set up correctly they will give you problems especially in a flat where you have neighbours from all sides (another good reason to point them at the windows)

one of your 5 a day?

I know a co that loves Risco the MD would definately wear Risco budgie smugglers if they made them, he is a bit strange

Most good alarm companies wont need the engineers code. It is a lazy way to take on a system, the new company should be defaulting the system and reprogramming it from scratch and a Veritas is not that big a system so should not take 20 mins to default and re-program. Defaulting and reprogramming is the only way to ensure that the system they are taking on is programed as it should be, and it is their own interest to do this as if it fails to perform they could be liable Alternately you can ask ADT to default just the engineers code, but they are entitled to charge for their time

I thought it was only me that did that

Sorry I thought you said you were working in the alarm industry

Maybe work more days rather an just Wednesdays
