Siemens FDO241 Guideline

Introduction
This document should therefore be regarded as a guideline. The fire size
specifications are reliable if such factors as room dimensions and exchange of air
in the room are taken into account. When this document is revised in the future, it
is, however, important that the experience gained from your practical tests in the
field is incorporated.
We are interested in hearing about your experiences!
We would be pleased to receive your comments and any data which deviates from
our own for inclusion in the revised version of this document. Please report your
experiences to the Application Manager at HQ.
1.3 Acceptance test fire
1.3.1 Type
When selecting an acceptance test fire, always compare the fire characteristics
with the fire detection principles of the fire detector. The following table shows
which acceptance test fires are suitable for testing the respective detectors.

Tab. 1 Suitability of the acceptance test fires
When selecting an acceptance test fire, side effects such as the generation of toxic
gases and soot, unpleasant odors etc. must be taken into account in addition to its
suitability. Furthermore, a fire must be selected which triggers a fast response in
the detectors. A detector which does not react promptly makes a negative
impression on the customer.
The following should be taken into account when selecting an acceptance test fire:
Aerosol generator SG3000
Demonstrating the function of a fire detection system using a "paraffin aerosol
generator" is very effective. The SG3000 produces easily visible "smoke" to which
the optical detectors react promptly without causing any other unpleasant smoke
effects. -> This acceptance test fire is the preferred option for smoke detectors.
Pyrolitic smoldering fire (TF2)
This is a very suitable acceptance test fire for testing the response of smoke
detectors in rooms with a maximum height of 7 m in which it is permitted to
produce smoke.
