Piro fire alarm system

[Curve]

Hi Im new to this site and have enjoyed reading some of the posts, I was wondering if any1 knew the minimum resistance reading for a new fire alarm system wired in 2core 1mm piro cable, I have wired and made of the ends and tested them at 500v and they are 600/700Mohms but the bosses say they want it upto >1000Mohms. I thought for a new installation the readings had to be >200Mohms but i wasnt sure, Just want to know if I have a leg to stand on if I argue with the gaffers Cheers [/i]

above 0.5. altho for new cable is should be very high/infinity

you could have got the end damp hence the lower readings. try leaving it a day or 2 and test again
