3.5.9

Can the operator

  1. silence auditory signals from any workstation
  2. acknowledge alarms only from locations where the alarm message can be read?

It should be possible to silence an auditory alert signal from any set of alarm system controls in the main operating area. An alarm acknowledgement function should cause the alarm's visual coding to change from that indicating an unacknowledged alarm to an acknowledged state. Acknowledgement should be possible only from locations where the alarm message can be read.
