I think point is gsm doesn't always work, I had a community centre with this problem dialler dialling out but poor signal occurred on there gsm so did nothing for a day until signal returned , in that case it polls once a day that's how they noticed
Dialler on its own is an issue but it's what people are prepared to pay, better to install a gsm unit along side and also use it to flag line failures etc , if prepared to pay , but most don't
Let me know what you need clarifying?
Are I see previous post, I still stand by my statement , perhaps rephrase a little "most diyers won't use all the outputs and will simply use one output from the panel to activate a dialler for notification, outputs on diallers are rare to be used by diyers , maybe a few do but most don't "
Only in my limited opinion and perhaps on the grand scheme of things that's what I have seen
If system is setup so zones can be omitted then yes , entering user code and looking through menu for omit , it may come up with no entries, if so then you must call an engineer
Naa man , you need internal sounders , bells can't be always heard outside , inside you want them to leave asap , although they know they have a little time , noise inside will hopefully annoy them
He won't be guessing much with a light beeping keypad , probably thinking ok I got 10mins to grab something as its quiet
Need noise man
Nah man some pir false alarm for all kinds of reasons , some cheapy ones can do so with interference , poor installation ie plastics bent seen all sorts
But I never had a problem with Honeywell pirs dualtec or standard
I thought this bell won't sound unless you connect the +12v?
Disconnect bell for a while, then leave plus 12v to bell disconnected at panel, reconnect at bell end , move link , close all tampers at bell , ie close covers put screw in , then last reconnect +12v at panel end
Something like that
I have the virtual keypad running on a dimension , they use it in combination with remote cctv , works well
Costing biggest issue , £50 for a card £5 for the app , cheaper than the other cards
