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.
9. Commissioning
When multiple detectors are networked together and a Command Module is being
used, the PC connects to the Command Module‘s 9-way RS232 port. The cable
connections are the same as the Standard Detector cable connections.
