resets, the following occurs:
• The buzzer remains silenced.
• Common Alarm LED turns OFF.
• Individual zone LED (if programmed) turns OFF.
• Cancels the alarm event with no log reference.

following occurs:
• Common Alarm relay activates if Aux disconnect is not active.
• The Auto Signal Silence timer activates (if configured).
• The Signal Silence Inhibit timer activates (if configured).
• If Aux disconnect is not active, activates all non-disconnected indicating circuits
programmed to the input.
• Activates non-disconnected strobes associated with the input.
