Setting the alarm threshold without “ASD Pipeflow” calculation
The following describes the procedure for setting the ASD 531 to one of the switch positions with fixed parameters
A/1
to
CC
.
Example
: The ASD 531 is to respond in compliance with EN 54-20, Class B. The sampling pipe is U-shaped with 3 sampling
holes per sampling branch. According to Sec. 4.4.4.1 switch position
B/6
is to be selected.

Notice
If there is a false or invalid entry (e.g. EN-Class A with 9 holes), LEDs “

a delay time. After a second delay time the ASD triggers a fault.
Point of departure: tube system(s) mounted and connected to
ASD. Smoke sensor(s) deployed in the ASD.
