6 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.
6.1 Commissioning Checklist
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 (for example, by use of different coloured wires or wire
identification sleeves) an electrical check should be made. Any damage caused by misconnection 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 4.1) and FIRElink-APIC board if applicable (see section 4.3).
3. Verify that the time and date are correct (see section 1.5)
4. Set an appropriate alarm factor for the protected environment. The detector will perform a FastLearn
for the new alarm factor. (see section 1.6.6)
5. Whilst the detector is still in FastLearn mode set the detector into demonstration mode (see section
3.10).
NOTE: 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.
