j.paul Posted March 29, 2006 Share Posted March 29, 2006 the idea of using pir's in 2 corners (not opposing corners) is that a pir is more sensative passing across its field than approaching/exiting away. so a much larger movement is required to get both pirs to trip. now overlapping the pirs would not be NSI DT254 but then its not monitored system either.regs arfur_mo Sorry if this is of topic, but I think you mean DD243, and it isn't a NSI policy its a draft BS document. There are no stupid questions, but there are a LOT of inquisitive idiots. Link to comment Share on other sites More sharing options...
arfur mo Posted March 30, 2006 Share Posted March 30, 2006 Sorry if this is of topic, but I think you mean DD243, thanks j.paul' its been a long day - but this systems not going 'registered' (i have assumed), so could be treated as BS.4737 Part 1 Bells only. in this case, if any standard was to be complied with, it could even be 38FF but i'm dreaming again so now to address your "it isn't a NSI policy its a draft BS document" remark, do not the NSI Inspectorate base their policies and subsequent site inspections in part at least, on a registered companies 'complience' with said BS.4737 draft documents, or what other standard is in force - if we are to be piccy that is? i was just trying to spoil the fun of the 'lets jump on arfur_mo' brigade and pointing out that it would not comply - as if i did not know it , and keeping the post short as possible - well that worked well did'nt it if we put every thing down to the letter every time it is then patronising to the recipient, so by mking a general remark it keeps the post a bit shorter (and some would love that of me ) and the recipient can always ask for further clarification - ok m8 phew! now i'm of to bed regs arfur_mo If you think education is difficult, try being stupid!!!!

thelockdude Posted March 30, 2006 Author Share Posted March 30, 2006 The system is going to be monitored. I assume NSI DT254, 38FF, and BS.4737 are UK codes and/or standards. We have different codes here in the US, and the systems I install do meet our local codes. (As far as I know, the squirrels are pretty much international).

bellman Posted March 30, 2006 Share Posted March 30, 2006 I have a site here in Sheffield that's plagued with them. I got that fed up with going back to repair chewed cables that I ended up sleeving them with aluminium conduit. They still had a good chew at that but at least it's holding out for now. Perhaps we should petition the cable manufacturers to impregnate the outer sleaving of the cable with a suitable poison Regards Bellman Service Engineer and all round nice bloke ) The views above are mine and NOT those of my employer.
