System limits without “HELIOS PipeCalc”calculation
The system limits apply to planning without the“HELIOS Pipe-
Calc” calculation software. There are two areas with the fol-
lowing meaning:
•
Normative system limits
compliant to EN 54-20, Class A
to C (or NFPA 72), switch settings
A11
to
C32
;
•
Non-Normative system limits,
switch settings
W01
to
W48
.
Normative system limits
Switch settings
A11
to
C32
have configured values which are
necessary for alarm response sensitivity and airflow monitoring
compliance with EN 54-20 Class A to C (or NFPA 72). The
switch setting designation is deciphered as follows:
•
First figure
Response class
A
,
b
,
C
compliant with EN
54-20 (or NFPA 72);
•
Second figure System limit
1
,
2
,
3
(pipe topology);
•
Third figure
Number of pipe networks
1
,
2
on the AMX.
Example:
b22
Response class
b
/ system limit
2
/
2
pipe networks.
Non-normative system limits
Switch settings
W01
to
W48
contain system limits which fulfill
only
the alarm response sensitivity for EN 54-20 Class A to C
(or NFPA 72)
but not
the normative limits concerning airflow
monitoring. Since these are identical to system limits
A11
to
C32
concerning pipe topology (pipe network length, number of
sampling holes), switch settings
W01
to
W48
are also included
in the tables below in section 4.4.4.3. Additional information
about switch settings
W01
to
W48
concerning number of pipe
networks and airflow monitoring can be found in Technical De-
scription FHB 34 (908142), section 4.4.4.4.
Switch settings
W01
to
W48
may be used only after
consulting with the manufacturer. The configured va-
lues theycontain concerning airflow monitoring are
not
tested inaccordance with EN (or NFPA 72).
Further information about using the system limits
table is found in Technical Description FHB 34
(908142), sections 4.4.4.3 and 4.4.4.4.
