5. Final testing
5.1 Alarm test / testing of smoke transport time
and symmetry
•
Introduce a puff of smoke (or use an environmentally friendly test
gas) into each pipe.
•
Note the time it takes to give alarm (= smoke transport time).
The time lapse should not exceed 120* seconds. If the exceeds 120*
seconds for one of the pipes, a larger hole can be made in the end plug
to this pipe.
* For agricultural applications the maximum transport time is 60
seconds.
5.2 Testing of air-flow monitoring
5.2.1 Introduction
This test will activate an error warning. If the test fails, check that the
error monitoring function is correctly calibrated and that the pipe
system has been installed correctly.
5.2.2 Simulated break in a pipe
•
A break in the pipe system is simulated by disconnecting the pipe
from the detector.
An error warning will be given.
5.2.3 Simulated blockage in a pipe
•
A break in the pipe system is simulated by disconnecting the pipe
from the detector.
An error warning will be given.
