What to do if the operator alert buzzer cannot be silenced on my Bosch Gateway?

If the operator alert buzzer on your Bosch Gateway cannot be silenced, there are a few potential causes and solutions: * The system may be stalled. Check the watchdog LED inside the door behind the keypad. The LED must flash for a running system. If stalled, try a reset power cycle of the D6600. * The [Acknowledge] key may be defective. In this case, order replacement part P6603. * The user interface card may be defective. If this is the case, return the D6600 for repair.
