Esser by Honeywell

(formerly Novar Esser) manufactures fire alarm systems, including the 8000 series. Their software (e.g., 8000 Series Configuration Tool , Esser Design , or Esser IQConfig ) is typically restricted access — only available to certified installers, system integrators, or authorized partners. This is for safety and liability reasons: incorrect configuration could lead to life safety system failures.
