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.
