System 600 APOGEE Database Dynamos for Intellution's 32-Bit FIX Owner's Manual
4-10 Siemens Building Technologies, Inc.
Alarm Areas
Alarm areas are configured within a node’s System Configuration Utility (SCU). Entering the
letter of an alarm area (letters A through P) specifies the local and remote nodes to which the
block’s alarms will be sent. Alarm areas also route event messages.
• ALL allows alarms from the block to be received by all enabled alarm destinations.
• NONE specifies that alarms will not be sent to any nodes.
•
Priority
Used for filtering alarms according to severity. If the block’s alarm priority is greater than or
equal to the node’s alarm priority, then it is recorded by the node and sent to pre-configured
alarm destinations. If it is less than the node’s priority, it is not sent to other nodes and does
not appear at any alarm or messaging services.
Alarm Limits
Alarm Limits determine when alarms occur. When the current value extends outside the
range of the high and low limits, an alarm is sent to the alarm areas.
For System 600 APOGEE points that are enabled for alarming and NOT enabled for
enhanced alarming, the high and low limits defined in the panel are automatically filled in as
defaults in the process database. For points with enhanced alarming enabled, an Alarm Block
must be used. An Alarm Block and a LAI block are both primary blocks, which require a
Program Block to link them
.
Security Areas
Provides write protection for the block. A user must have access to the security area to
change the value of a write-protected block.
• ALL assigns the block to every security area.
• NONE does not assign the block to any security area. If there is no security area, the
block is not write-protected.
