Red for bed..

PIR type sensors should be mounted facing perpendicular to the risk not at it.

Maybe Bosch BluLine Pet DT's right through so you have options? You can then choose either pet alley mode or do perimeter protection in pet areas which is the preferred.

I only use Optex or Bosch myself therefore minimum quads as standard in any "living" rooms. Dualtech for harsher environment like garages etc. Sensors would normally cover a full 12mx12m room so two in one room is unnecessary unless you have blind spots. Consider ditching the tiny internal sounder built into the Poly cab and fitting a proper one elsewhere, something like a CQR Alto extension speaker or the like. Contacts minimum on any entry door others optional unless in pet areas. Wouldn't recommend glassbreak, better with shocks if your doing windows but consider bird strikes on large bi-folds and windows. If you have any sense your unlikely to have much of an issue screwing whatever to the wall it's the design, knowing how it all programs and fits together you would likely come unstuck on. Expect may hours of reading manuals, pressing buttons and terminology only alarm monkeys speak before you get something near working.

I would fit a Poly panel in this instance. I have used an expander for short wires but I fail to see how it would help in this case. While the Metal cab has more room inside looking at the distance from the cable entry to the PCB you would be better with the Poly Cab IMO.

I wouldn't extend them there is enough there for a Premier. Just open up the plaster and containment for what you need then mount the panel to cover the hole.

Thought the old school engineers did the spark and rattle test?... I think ACT is pretty much industry standard TBH, Yuasa one is a lot more expensive.

Also I wouldn't bother with 4 or 6 any more. Much easier to standardise on 8C, spare cores can always be useful.

It's cheap CCA Type 3 garbage, you get what you pay for. Only use CQR pro here.

I was just going to say Greggs have there own facility company do it.

Most companies will put your company logo on for free if you order a batch

Bellboxes take a beating; either by weather, temperature or burglars. Discrete components are more resilient to this.

Bentley Symphony was the first microprocessor IIRC?

24 would be fine

It's like an "international" version of a Premier, not so popular over here but still produced AFAIK. No prox tags on any version, I imagine unlikely to be able to upgrade it to the latest version with such old hardware either. Most are easily replaced with a PE48 as only go upto 832. Check for a plug on expander and remote expander versions for compatibility tho.

Can't beat a wired system, I'd at least choose something hybrid so if you have an issue with the wireless you have options.

They are a pretty basic panel you have to wire the sensors into the correct zones. Zone 4 is likely just un-configurable, so full alarm all the time.

Are the tampers on the box closed correctly? Don't know the panel or the bell too well but seems right.

Don't link them out, program them out. You should get resistors with the kits and they are DEOL default normally.

When it's comes to business banking I have heard bad things from a variety of businesses about all the high street ones. Can't say much about Metro tho which are down south.

I would say you maybe worth considering a partnership type deal where you pass security to someone and they pass you electrical and minor works for spurs. They are two completely different disciplines IMO and although there is overlap like with all things in BS7671, generally for most places it's not beneficial to do both.

The dinosaurs died out, alarm monkeys are now the rare species...

Poor installation of the cable doesn't mean that it wasn't tested tho. There is a big difference between wiring eight core or flex straight off the back of a socket (both I have seen) and a well installed 3A spur without a MWC IMO.

You'd be amazed what creatures get through a 20mm cable opening on the back of the cab.
