My last question (fingers crossed) I have installed all of my Veritas R8 alarm system apart from the external bell box. Will the alarm function correctly without this as I have an internal sounder & wanted to make sure the PIR's were deffinately pet imune before annoying all the neighbours? This is the easiest way I can think of checking it as it obviously needs to be set (I can't ask the cats to do a walk test for me!) and it'll probably be a little while until I get round to fitting the external bell anyway.

it should run fine without an external bell

yes but leave the little link in, so as not to create a tamper.

Another good way to check put the said PIRS in to soak test the texecom r8 has this compatbilty and will just write activations to the log

i would be more tempted to programme a very short bell ring time and no rearm for the activated zone just in case there is a break in

As it was said before the panel will work fine if tamper link is fitted in panel...i would deffo fit external bell a.s.a.p as just seeing it is a deterrant and it may mean your neighbourhood burglar goes on next door/street
