Alarm Indications
Attendant 
alarms
Your SelecSet 500A attendant console can receive various 
alarms, depending on how the system is configured and 
what keys you have programmed. This section describes 
various alarms that may light lamps on your console and 
the action you should take when you receive the alarm.
Receiving a Combined Alarm
Combined 
alarms
This alarm conserves the number of keys that are assigned 
to alarms. The <CALM> (combined alarm) key combines 
the system, PMS and VMS alarms (you can still have 
these alarms programmed on separate keys) and answer 
detection alarms.
The lamp associated with the <CALM> key lights when a 
malfunction is detected in the system, the answer detection 
link, the PMS/PMSHOBIC link, or the VMS link. The 
CALM lamp stays lit until the problem is corrected.
