Don't have any Pre Elite panels they're for the bin if they get ripped out TBH.

I'd be asleep by 3

I can't see it being supported configuration at all but plausible that the expanders could be "understood" by both panels they wouldn't be "linked" in that sense tho.

Most likely two separate systems. Connecting two via data isn't a thing AFAIK, certainly not supported if somehow that is the case.

Ideally you would have the system serviced annually and as part of that the batteries in all the devices would be replaced as required, I assume there was a reason for cancelling that? ADT Visonic systems use components that run on a different frequency so support for replacement parts would be limited to ADT without buying second hand. While it's possible any engineer maybe able to get you sorted if it's simple or just batteries, but your going to get limited support and may not be able to get the app back online. One thing that may point you in the right direction if you keep pressing the "i" button it should point you towards the faults stopping it from arming.

I thought you where better than that?

Does look like the safety of the shed now to be fair...?

Been a while and only played with one but don't you use the last 4 digits of the account number on the panel with dial capture? It may well be just something not setup on CSL end tho

Not saying it wasn't good well built kit and worked well, that doesn't take away it was overpriced that was confirmed to me by an ex-DM guy.

DM was overpriced and look what happen to them for not innovating and trying to compete.

Especially ADI

High and low sensitivity in panel end and pulse count is per sensor, they are completely different things.

Nope on the PIR's

I wouldn't if you can avoid it, inertia things with 1/2AA batteries they're expensive for what they are too. In practice it's the right idea to go perimeter, just unfortunate the kit your working with.

You can lower the pulse count but you'll loose the pet friendly mode. Yes they are one way, so also sleep for a few minutes in normal operation mode. It's one way and pet friendly I wouldn't expect much guaranteed protection from it.

They're are not great pickup on the default settings and are useless outside the strict mounting height in the manual.

The intruder panel would control the heating from the systems set status not the beams. You can open a can of worms here, every installer would use different kit from different manufacturers to do the same job, difference is if you know how to install and program it. Most top end commercial panels are capable of controlling auxiliary kit if you know what your doing.

Security is about layers start from the core and work out. If the perimeter system fails to operate or false activates and cries wolf all the time your left with nothing for your investment (both time and money). You can buy all the "best kit in the world" and apply it wrong you'll still have a poor system.

I wouldn't class anything Hik "premium" myself. They don't sell/support proper Hik to end users so they can't aim to confuse end user, even if they change the model numbers all the time. Agree with above, there are so many mistakes to fall into with DIY CCTV, maybe have a look at some of the other CCTV threads here.

Ding! But I prefer beams over beans tho

Spotted your initial post but I wouldn't personally use hardly any of the kit you posted about. It also seems like a bit of an odd setup to be asking these questions. Sounds like some early warning system that may false alarm a lot, as above. I can help with the Optex beam question a little, the SL version comes with an extra external housing and has more power options (i.e you could wire power). Would say all the extra features would be unnecessary for domestic situation tho, they are both decent wireless beams with more than enough beam range for most domestic applications.

Box cameras are all designed to be standard fit to a box housing, assuming the heater functions and there's no corrosion on the housing no need to swap it. They have two types of lens mounting C and CS if you are reusing the lens.

Assuming everything else is fine it's just a simple but possibly awkward to get at box camera swap?

I am glad you found the forum useful, forums are generally for discussion on topics which you were a part of over your 10 posts. Multiple people in the trade answered your initial question within 1 hour during the weekend, which you would do well to find anywhere else. If you would like some over-opinionated social media bull, lecturing, false information or useless memes, feel free to ask your questions on twitter or facebook in the future.

There maybe a clause in the employers contract to waiver the work time regulations due to unforeseen circumstances where necessary by the company. Nationals would normally be flexible enough to allow at least part of the next day in lieu, smaller companies wouldn't normally have the resources. It shouldn't be us versus them when it comes to employers and employees, it's an unprecedented situation. Working together with everyone to find balance between making sure you all have a company to go back to and not breaking these regulations will benefit everyone.
