6.4 Alarm Buzzer
The alarm buzzer produces three types of sounds:
• Single beep - when any Control button is pressed
• Single beep repeating every two seconds - the system has a general alarm
• Continuous - the system has a serious fault
If the alarm buzzer makes no sound, the system may be operating properly or the alarm may have
been silenced manually.
