It's around £60 for a 412 with keypad out there if that adds any context. Anyway feel we are sliding off topic, OP feels competent to DIY and is in the DIY section? If you do all the checks i listed above you will have an idea if it's the controls or not then you can proceed from there.

It's all relative tho H, the average salary in SA is around 15000ZAR if your lucky whereas it's more like 30000GBP in the UK. It's not just about the 18% exchange rate. From what I know security is more costly over there, I do agree it's all relative tho if you want the work done you pay the going price.

Looks like a Premier 412 Export. I can only suggest defaulting and programming again, there maybe something you have missed. You need to find out if it's the circuit or the panel is at fault and then from there if the panel detects the zones or if it's programmed incorrectly. If programming it may just be the circuit isn't in the correct area or something similar. We don't see the international series panels over here much so don't know the programming sequence in depth as a "normal" Prem. Also as above the two circuits will not operate correctly in parallel although you say the reed is bust on one so for now it should be ok for the one that works.

Maybe post some pictures of the panel, sounds like an old export model from what you have mentioned.

£150 including the keypad?

All down to how you set it up in the programming.

Prosys is up there with a Sterling too, how relevant.

If biscuits where still around for Grade 3 they would just have 5 legs instead of 3. I think BUS detectors where a better idea, issue is your tied to one manufacturer then.

It could be pretty unreliable I am glad it's not still around TBH.

It's not marketing any more it's Cambridge Analytica style brain washing....

It's a Visonic Powermax Express they are now discontinued

Delay 1 and 2 are likely two different delay timers but yes they are the "entry/exit" zones. Instant is what it says instant alarm. So yes you would have this external sensor on Delay if you wanted time to leave. As I say you would normally have delay on as minimal as possible circuits, just enough to get to the keypad for example a front door.

Adding an exit delay to something that you need to trigger instantly defeats the object of having the sensor. It's going to need the entry delay to expire before the system triggers you should consider other options like resiting or masking the PIR if you have to. It's a bit of an odd setup we wouldn't protect stuff like this in the UK

Exit delay isn't really the best option here can you not reposition the sensor

Don't fit Pyronix never rated it TBH, so not sure about the specific issue. If it's not fit for purpose use something else.

PCU5 is to make a wireless beam powered with a 12v conection

Not a beam but Texecom KIT-0079, 12v buzzer in a 12v boxed PSU. An alarm panel option wouldn't have to be used you enable chime and leave it alone. If you "have to" use the Optex beam I suggest using the transmitter they recommend, normally they have a Inovonics one.

I didn't recommend the beam it's a good product but just explaining the costs. Maybe the Takex is the right product if you know how to put it together. Anyone can throw an alarm panel at it. I have used Ricochet contacts to send signals back for example. Again this all goes back to X Y Problem.

Takex and Optex are similar quality kit. The Takex unit and the Optex with it's separate C form compatible transmitter unit will likely be similar cost wise. The idea with the Optex unit is you can choose any 3.6V C Form compatible transmitter or series a few beams on the same pole onto one transmitter. It also means you can select a radio frequency best suited to the country and application. Again we are talking professional grade perimeter protection here.

Well yes EN50131 refers back to BS4737 in a lot of cases.

We are talking professional grade kit designed to work in all weathers and through dense fog, not a £12 doorbell. Maybe ebay or online electrical retailers have something less pro that will suit your door bell scenario, if your not worried too much about reliability.

Everything gets old eventually

More items are using 868 now as 433 was congested. 868 is now very close to 4G mobile too. Your better to safe your money than fit DIY tat I would normally fit wires where possible but that doesn't mean a professional grade two way security system wouldn't be stable.

Minimum, maximum can be about four years if never activated. The is an option in the Master User Menu it gives you a period of time to replace batteries, TBH I have seen the option but never tried it, not had time to flash the test panel recently. It has to be enabled in the engineers for the option to be enabled to the master user only.

I agree there is XY Problem here. Is it just for chime? Can it be connected to an alarm? If you can only do radio you need some type of receiver house end.
