  8. http://www.powerstream.com/cr123a-tests.htm
  9. The problem is a litium cell will loose approx 0.5 - 2% of its capacity a year depending on brand. Couple this with the low power draw of wireless devices the curve just drops of completely very quickly. The difficulty for the manufacturers is at what point do thy report a low battery. Too early and it looks like its running out of batteries, too late and the low battery running time is either very short of non existant. The low voltage volts will depend on the manufacturer and cannot imo be the same for all manufactures. I suppose the answer is to have it programmable so the maintainer can choose when it goes into low battery and how long it will function for in tht state before the supervision failure
  10. means nowt as yu know
  11. would an enforcer perform any better in that way than say a yale? and that's cheaper
  12. technically yes, most councils will give retro planning permission. But as dudley (mine) said depends on the numbers
  13. as h, its an illuminated sign blank ones ok. As such needs planning permission
  14. a volt check means nowt, you never did that on the sla as a good test. Depends on the gear experience will out.
