6 Alarm System
The alarm system is an important part of the BMPC/2 and is needed for the supervision
of the magnet system. The alarm system uses an analog telecommunication network,
based on an analog fax modem (with its own modem controller), and normally is avail-
able for use worldwide.
6.1 Alarm System Function
When the BMPC/2 is working in the Monitor & Alarm mode, all system parameters are
continuously monitored and compared with their limit values. When a parameter
exceeds or falls below a given alarm limit, an alarm cycle will be started.
In the following example the alarm cycle was triggered because of a low helium flow.
The status field shows that an alarm call was activated and the resulting events logged
in the Event Log section.
