Commissioning
Before commissioning the detector the local standards of aspirating detection systems must be consulted.
These standards differ widely throughout the world and specific advice for the market in one country may not
be applicable to another.
Commissioning strategy will initially depend upon the environment in which the detector is installed. For
instance, the test for a computer room (which should be a relatively clean environment) would be very different
from, say, a flour mill, which would probably have a high level of airborne particulate content.
A widely accepted standard for computer rooms/EDP areas is British Standard BS6266, equipment
overheating at a stage well before combustion. To perform the test electrically overload a 1 metre length of
PVC insulated wire of 10/0.1mm gauge for one minute using an appropriate power supply. The detector has
two minutes from the end of the wire burn to give an alarm indication.
For areas with higher levels of background particulate matter testing methodology
would be similar to that of standard point detectors.

Commissioning checklist
The following brief checklist allows quick setup of the detector. This procedure will be adequate for most
standard installations.
Before powering up the detector, visually check all cabling to ensure correct connection. If wire identification is
not immediately clear (e.g. by use of different coloured wires or wire identification sleeves) an electrical check
should be made.
Note:
Any damage caused by misconnection of the detector is not covered by warranty.
Power up the unit and connect to a PC and set the address switches on the detector board (see section 7.1)
and APIC board if applicable (see Section 7).
Verify that the time and date are correct (see section 4.2)
Set an appropriate alarm factor for the protected environment. The detector will perform a FastLearn for the
new alarm factor. (see Section 4.6)
Whilst the detector is still in FastLearn mode set the detector into demonstration mode (see Section 4.11). NB:
Aerosol-type synthetic smoke sources should not be used to test the response of the detector as these may
leave acidic residues which could cause damage to the unit.
Wait for the FastLearn to finish and the flashing OK LED indicator will finish and perform any necessary smoke
tests, ensuring that the detector reacts appropriately, and let the smoke fully dissipate.
Perform another FastLearn, this time not putting the detector into demonstration mode. The detector will
generate no alarms during the 15 minute FastLearn period, and after this the detector will operate at a reduced
sensitivity for 24 hours whilst ClassiFire acclimatises to the protected environment and sets up appropriate day
and night sensitivity settings.
