Acceptable resistance when adding resistance to supervisory inputs

Issue

What is the acceptable range of tolerance for resistance on a supervisory input.

Product Line

Andover Continuum

Environment

  • i1 controllers
  • i2 controllers
  • b3 controllers
  • I/O modules

Cause

Doors are being retrofitted, and the resistors that are installed are not 10K ohm and are inaccessible.

Resolution

The tolerance for the resistance on supervisory inputs is +/- 3%.
