PERIODIC ALARM
General Description
This feature can indicate the alarm on the Dterm function key or external alarm display panel for
periodic inspection.
The PBX controls the time of periodic inspection, and when the time (assigned by CM43 Y=2)
comes, indicates the alarm.
Figure 1-2  Periodic Alarm Indications
Service Conditions 
(1) Use CM43 Y=2 to assign the time (year, month, date, time) of periodic inspection; for 
example, battery exchange.
(2) When the time of periodic inspection comes, the D
term alarm function key lights when the 
setting is the MJ alarm, or flashes with 60 IPM when the setting is the MN alarm. At the 
same time, the alarm display panel can indicate the alarm.
(3) Up to two D
terms in a system can indicate the periodic alarm.
(4) The alarm indication can be cleared by assigning CMEA Y=1 from CAT/MAT.
