Physical status

Knowledge Base - Visualization alarm system in keymap™

The physical status states which resistance the system measures in the detector circuit:

Example values are valid for a DEOL 4k7k

The physical status can be separated thus into 3 groups:

  • Extreme resistance values which can only be explained by sabotage of the detector (‘Sabotage closed’/ ‘Sabotage opened’), this alarm situation will be notified with the highest priority – independent of e.g. the detector operation
  • Unusual resistance values which cannot be explained by normal detector operation and e.g. can hint on cable contact (‘Low resistance’/‘High resistance’)
  • Resistance values, which the detector can assume at regular function (‘Normal’/ ‘Open’)
