Oxo Posted June 22, 2013 Share Posted June 22, 2013 Active beams are very stable, only thing id say that is more stable is a door contact. I wouldn't use them to activate an full external alarm. Nut i have used them like this and fitted local sounder, low output, to show the perp if it is one that something has detected them. Volume isn't really required in this type of system imo Seen contacts to be poor and cause issues. Anyone going to post here now how they never fail? Only times I have seen beams fail is physical damage or power outages. FA`s, none as they are/were set up and positioned correctly....................Always inform the customer that "small" Rosebush/Triffid does walk about at night Link to comment https://www.thesecurityinstaller.co.uk/community/topic/34810-back-yard/page/4/#findComment-329067 Share on other sites More sharing options...
norman Posted June 22, 2013 Share Posted June 22, 2013 Not worked on Top end circumstances then. Would have thought "aunty" had a few. Yes and never seen anything external perimeter linked to a main system. Bad practice imo. Nothing is foolproof to a sufficiently talented fool.

Oxo Posted June 22, 2013 Share Posted June 22, 2013 Perhaps for you. As you say "IMHO". Sorry your "IMO" Been asked and done it. Royal families of more than one nationality seem to think what they want goes and not what the so called expert thinks. So beams used with the main system externally yes.

Oxo Posted June 22, 2013 Share Posted June 22, 2013 Fairy Muff. You accept the fact perimeter is an integral part of specialised detection. Thus can be and is integrated Into the main system of the protected premises. Next you`ll be saying CCTV integration and monitoring combined with perimeter isn`t right when connected,,,,,,,,,,,,SORRY integrated.........???

bee_man Posted June 23, 2013 Author Share Posted June 23, 2013 OK, thanks all. Many differing opinions, but I don't think anybody has really given any reasons other than misalignment. Is it possibly not OK to give reasons in public for fear of informing he of the black and white striped tee shirt and swag bag? bee Link to comment https://www.thesecurityinstaller.co.uk/community/topic/34810-back-yard/page/4/#findComment-329135 Share on other sites More sharing options...
