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.
The following brief checklist allows quick setup of the detector. This procedure will be
adequate for most standard installations.
1. 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. Any damage caused by mis-connection of the detector is not covered by
warranty.
2. 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 7.3).
3. Verify that the time and date are correct (see section 3.1)
4. Set an appropriate alarm factor for the protected environment. The detector will
perform a FastLearn for the new alarm factor. (see section 3.7)
5. Whilst the detector is still in FastLearn mode set the detector into demonstration
mode (see section 3.10). 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.
6. 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
(within 120 seconds for LPCB compliance), and let the smoke fully dissipate.
7. 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.
