Chapter 4: Commissioning
58 LaserSense HSSD-2 Aspirating Smoke Detector Installers Handbook
Introduction
This chapter covers the commissioning procedures for the detector. 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
The following brief checklist allows quick setup of the detector. This procedure
will be adequate for most standard installations.
To commission the detector:
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 colored wires or wire identification sleeves), an electrical check
should be made. Any damage caused by misconnection of the detector is not
covered by warranty.
Caution: Ensure all wiring connections are checked prior to powering up the
detector. Incorrect wiring of the detector will cause permanent damage to the
detector.
2. Power up the unit and enter the Installer Access Code. The factory default
setting for this is 0102. (See “Entering programming mode” on page 39 for
details.)
3. Ensure all detectors in the network are clear of troubles and alarms, if
applicable.
4. Enter the Setup menu and verify that the time and date are correct. (See
“Time and date” on page 45 for details.)
5. Set an appropriate alarm factor for the protected environment. The detector
will perform a FastLearn for the new alarm factor. (See “ClassiFire alarm
factor” on page 45 for details.)
