Introduction

A Rule Disarm Check can temporarily disable a rule for a configured period of time. For example, a technician may be sent into an Area to perform some maintenance, and they can press an external trigger to disable an alarm whilst they are doing their work. This alarm will then be enabled automatically after the configured period of time.
