Compliance
Praesideo is compliant.
Using the Open Interface requires access level 2. The
Open Interface functionality is limited to call and BGM
(Background Music) control as well as acknowledge/reset
of fault and emergency states.
Praesideo provides control input contacts with supervision
and control output contacts for external control devices,
with extensive configurable functionality.
The Praesideo system operates as an autonomous system.
All external activations are priority based to control
preference. By proper configuration system behavior is
tightly controlled and the mandatory functions of the VACIE
will not be overridden.
The Praesideo system operates as an autonomous system,
so its operation (functionality) is not affected by loss of
connection to an Open Interface client.
The connection to an Open Interface client is monitored by
means of a keep-alive mechanism; if the connection is lost
the general fault warning indicator is activated and a
specific fault is reported.
