What does the S4 push button do?

• A. Turns off the audible alarm sonalert LS1 but does not reset the alarm condition on the panel
• B. Resets the alarm condition on the panel
• C. Turns on the audible alarm
• D. Clears the display

Answer: (A)

Silencing the audible alarm is what this push button does. Pressing it stops the Sonalert LS1 sound, letting you work without the constant noise, but it does not clear or reset the actual alarm condition shown on the panel. The alarm state remains active, so you know there’s still a fault to address. To clear the alarm from the panel, a separate reset/acknowledge action is typically required after the issue is resolved. In other words, it turns off the sound without changing the panel’s alarm status, rather than resetting the alarm, turning the sound on, or clearing the display.
