7.5 Testing response behaviour in cabinets
The TITANUS
RACK·SENS
®
1U
system must be switched to service
mode for the following tests.
Ensure, that the TITANUS
RACK·SENS
®
1U unit will only be set to “ON”
after the test, if all alarms have cleared out.
The PYS 100 pyrolysis system determines fire alarm system response
behaviour, especially for highly sensitive air sampling smoke detection
systems. The pyrolysis system is designed to simulate an electric fire in a
compressed time period through a reproducible smoke test.
The system generates defined quantities of pyrolysis particles and smoke
to be reproduced under the same ambient conditions, so that changes in
the response behaviour of the fire alarm system can be detected when
the test is repeated.
•
Pyrolysis phase when invisible smoke particles are released.
•
Smouldering fire stage when visible smoke particles are released in
quantities which match the response sensitivity required by system
design.
The pyrolysis box is kept closed when operating in difficult-to-access in-
stallations such as control cabinets as well as false floors and cable con-
duits. The pyrolysis particles produced are then fed in a tube into the
cabinet being monitored.
