Chapter 5: System commissioning
Introduction
This chapter covers the commissioning procedures for the air sampling pipe
system and detectors. Commissioning results should be recorded on the
commissioning check sheet.
Commissioning
The commissioning check sheet should be completed upon commissioning of
every air sampling pipe system and detector. The purpose of this sheet is to
document proper system operation and acceptance by the owner, to provide
reference data for future testing and maintenance of the system, and to register
serial numbers for warranty. Completed and signed copies of the commissioning
check sheets should be distributed as directed on the sheet.
Precommissioning preparation
After the air sampling pipe system and detector have been completely installed,
they must be inspected and tested and all configuration and ambient conditions
can be recorded.
Before starting the commissioning tests, go through the following
precommissioning preparation steps:
1. Perform a visual inspection of all air sampling pipe system and detector
hardware. Check that all system equipment has been mounted properly and
wired correctly.
2. Leave all detectors in operation for a period of time to allow the remaining
particulate matter that may have been left during installation in the pipe
network and/or ducts to clear out of the system.
3. Check that all detectors in the system are cleared of all trouble conditions.
4. Isolate all detectors or disconnect all alarm and trouble circuits to prevent
communication of alarms and troubles to ancillary equipment.
Commissioning is recommended after all construction has been completed and
the area cleaned of any lingering post-construction dirt. If ambient monitoring
conditions are recorded before the installation is cleaned up, they may not
accurately reflect actual normal operating conditions that must be used as
reference data for follow-up maintenance procedures and tests.
