Default Which Home alarm system?

TBH I can't remember what came but I know there was a lot of EN
compliance stuff on many of the parts. CPC are bad for not updating mfr
part details like that on a developing product and I wouldn't be surprised
if it is ENs that get shipped when UKs have filtered thro the stock.


It may well be.

I think it's one where a laminated crib sheet is more useful
than the user manual.


Very much so, indeed that goes for several consumer devices (the absolute
worst being DVD recorders which as a rule have simply ghastly interfaces :-)

Ability to label zones in alpha (so that it shows 'back door' rather than
zone05).


An improvement that should have been done even to the LED ones.
A simple slide-in letterplate backlit by the LED if necessary.

But there are weaknesses:
Counter intuitive user reset after alarm/power fail etc: Enter code a second
time and hit Tick for Yes to reset (I was used to No to reset).


I do wonder if they actually bother to flowchart them.
Then again I've wondered that about the programming industry for years :-)

In common with seemingly all cheaper panels low power feed from panel
(1A), fine for accessories but I like a lot of sounders and the limit was
busted. I know I could use SCB set sounders instead of SAB but I put in a
separate fused feeds direct from the battery to spread the load.


As a rule treat it as 0.8A, because at 1A the regulation can go to pot.
Easy enough to add a second PSU - but it adds another box, space etc.

Also the higher the current draw, the higher shorter the battery life on
standby;
and battery life also diminishing with time which can lead to odd behaviour.

Thanks.
