No there is no magic off switch, this would defeat the system. Systems need to be maintained or they will let you down. If the system has lost it's memory the NVM is failing the system should be upgraded.

Most will say the panel has done it's time, I'd agree. You say it's in working order but what tests have you done to prove this? how regular has it been maintained over it's life? Buzzing transformers are often a sign of overloading when it comes to alarms they can go that way with age but usually if you test the panel has too much load. Occasionally it can be the mounting of the panel is uneven and amplifying the sound which can be checked but usually it just a sign it will fail. If you really what you locate a replacement with the same rating you could, but it will not be long until something else will give up.

Yale easy to kill with no sound but it's not graded, just DIY junk.

We don't provide defaulting information or manuals here as per our guidelines. External sounder only lasting 5 minutes means something is wrong. B or A would be the sensible, depends if you actually care and/or if your insurance cares.

I wouldn't pull anything off the wall unless you had a backup plan for if your external sounder will not silence itself; like a set of ladders and basic tools. There is no magic off button or procedure, that could be exploited. If you do pull it off the wall just be aware of the electrocution risks.

If rental I'd be thinking about if its for use by the tenants or if it's for just between tenancy, before making any decision on a new system, installer or not etc.

It's all covered in the thread please read. Please start a new topic.

Does it make any sound or is it only the entry/exit tones? If it's a loudspeaker then you can check it's impedance and wiring from the panel. Either way you need a mutlimeter and some idea how to use one, unless your going to diagnose with trial and error.

Took weeks but here's the statement from the company. https://community.security.eufy.com/t/to-our-eufy-security-customers-and-partners/3568215 Apparently "local only" means use the cloud for messages but not analytics... who knew... Pft joke of a product and company like the rest of this pro-sumer tat.

Zone inputs but you need to program them accordingly.

A Premier 24, £4 W1209 module and custom outputs...

Website says EN50131 (Parts 1,3,5,6,10) but your declaration of conformity appears to not...?

Evidence tracking advertising works then...

I thought you had swapped the RIO?

I am no Galaxy expert but have you done any tests on the bus? I have known people to remove the termination to solve some issues. Is there a ground loop? Resite the RIO adjacent to the downstream one on a metre of cable?

ADE Accenta, all obsolete now. Best to upgrade system of that age. Not working in what way? What is the condition of the rest of the system? You could risk buying used but who knows how long that will last.

I don't fit Ion however... This seems like "Siren battery" so most likely an external siren. Most wireless systems do not alert when they are armed, some panels you can silence these beeps for a short period of time (disarming procedure). Ideally you wouldn't let the system battery get to this point. When was the system last serviced?

I didn't know iron oxide was so expensive... If I leave old metal panels out in the rain do they go up in value?

Depends, I have known panel to sink negative and retrigger the hold off.

That is correct. With a fully operational system if you power down the inside the siren will activate. Fully decommissioning a system usually involves ladders and earplugs. They are designed that way so a burglar can't disable them easily from the inside.

Not the best but not awful if you bin off all the stuff they did fitting the Dualcom.

Issue is when the company goes bust... If you have a service contract you wouldn't make e-waste anyway, your installer would support it or you move to another supported installer. It's stuff that's fitted then not looked at until there is a fault that causes e-waste issue anyway. Installers aren't necessarily to blame. It also can be used to make sure all service contract payments are complete before handing over to another company.

Not the best audio but examples of how poor "pro-sumer" door bell and camera systems can be, despite what the manufacturer claims. https://www.youtube.com/watch?v=qOjiCbxP5Lc https://www.youtube.com/watch?v=etpbq_HH79c

There is a defined line with fire systems and programming, you can service or work on a system and not change how the system functions. If the system isn't operating as commissioned it will throw a fault. The commissioning engineer would remain responsible, that all makes sense. I would say intruder most is not demarked in separate level menus like this and difficult to define like that if it hit the fan. But yes it's how you or the insurance interpret it, I am certainly in agreement you should default on incoming.

You say "unfortunately" being responsible for your work is all part of the job. It's not an issue if it's your own contracted system. I don't see how you have evidence of what was programmed or not to prove liability. There is no written evidence of every programming option. If someone defaults codes only they have changed the programming, if someone changes if chime is on and off or user codes, they have changed the programming...
