• To silence the panel sounder and any activated outputs that are programmed as silenceable:
Press the
The control panel sends an Signal Silenced message to the remote annunciators, history buffer,
installed printers, and CRT-2s. The figure below shows a sample Alarm Silenced message.
1. Check the Alarm message for the location and type of trouble.
2. Correct the condition causing the alarm.
3. When you finish correcting the alarm condition, press the
control panel to normal operation (indicated by the "System Normal" message). The control

3.3.3 Interpreting Fire Alarm Type Codes
The Type Code that displays in the Alarm message indicates the function of the point that initiates
the fire alarm. For example, a monitor module with a
monitor module connects to a manual pull station. The table below lists the Type Codes that can
appear in an alarm message:
