STT11CPU
STT11 CPU is the main unit of the STT11 system, designed for performing automatic actions (called `fire actuations`) following
the detection of a fire alarm.
It is made up of a physical and logical tree.
The physical component list includes the physical control unit with power supply, the I/O boards, and the local operating
terminal.
The fire system is logically organised in a 4-level structure similar to the one used by AlgoRex.
The structure is based on a geographical and functional tree:
- Area;
- Sections, which can be Security Section or Input/Output Section;
- Functions, which can be Security Function, Input Function, or Output Function;
- Elements, which can be Security Element, Input Element, or Output Element.
System limits:
-1 Area;
-99 Sections;
-192 Functions;
-128 elements.
History:
v1.08 : Elements local properties "fault", "in command", "command OK","fault safety position" and "fault wait position" are now
propagated using new common properties "element..."
v1.09 : Updated to fit CNAP v2.3u
