I have an old Elite Version II security alram (Arrowhead? or Crow?), and it was without power for few days as the section of the house was isolated for few days. It was on battery backup, but the battery ran out after few days. After I opened the panel and checked the battery, the unit went in Tamper state and would not accept the code as well. As of now I have taken out the fuse and the battery, so no power at all. Searched the net for installation manual, but could not find it. Arrowhead's website requires login for any downloads, and not even sure if the manual is on the site.
Would anyone have the manual or can offer to help?
