4.3.7-1 Separate Controls for Alarm Functions

Separate controls should be provided for silence, acknowledgment, reset (acknowledging an alarm that has cleared and returning it to normal), and testing.

Additional Information:
A global silence capability together with separate silence and acknowledge capabilities can be useful during high alarm situations by allowing the user to silence many distracting alarms and then acknowledge these alarms at their respective panels. A variety of controls is possible, such as pushbuttons, function keys, and on-screen controls.
