  1. There isn't an ideal way. Loading a battery and Volt testing will show accurately but doing that on a primary cell will affect it's life so all you can really do I Volt test. But I don't know that much about batteries in the level required
  2. its doable but its the data demand on the sim you want to worry about
  3. you want to use wireless to router or 3/4g?
  4. sla was sealed lead acid. Any cell wil only give a decent reading under some load.
  5. yes its a circuit on the gal but still id use technistore
  6. thats it its your sdp but with the device types locations etc as fitted rather than planned, if any different
  7. the galaxy supports it directly just enable it
  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. would an enforcer perform any better in that way than say a yale? and that's cheaper
  11. technically yes, most councils will give retro planning permission. But as dudley (mine) said depends on the numbers
  12. as h, its an illuminated sign blank ones ok. As such needs planning permission
  13. a volt check means nowt, you never did that on the sla as a good test. Depends on the gear experience will out.
  14. no its a software thing i cant think of the name of either ill have a look
  15. is that the actual keypad or a google. Honeywell had a system before the 2-20 after the 16+
  16. there is that german one. plus ispy as a cheapo option. Genie also rebadged one assuming windows based
