Note:

The loss of -48 volt power prevents detection of an external device alarm. 
AC-POWER, CARR-POW, and DC-POWER alarms could indicate the loss of the 
external device alarm -48 volt power source. ALARM-PT alarms may also 
indicate a loss of power. When analog line ports are administered as analog line 
external device alarms loss of -48 volts prevents detection of an external device 
alarm.

Always investigate tests in the order presented in the table below when inspecting errors in the 
system. For example, by clearing error codes associated with the Battery & External Device 
Alarm test (#120), you may also clear errors generated from other tests in the testing sequence.
