Precommissioning preparation
Commissioning should be performed after all construction has been completed
and 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 need to be used as
reference data for follow-up maintenance procedures and tests.
Acclimation period
The detector will operate at a reduced sensitivity for 24 hours. ClassiFire will set
up the appropriate day and night sensitivity settings. All air handling units,
thermostats and other systems that can have an effect on the operating
environment should be turned on to simulate normal operating conditions as
closely as possible. After approximately one week of monitoring time (depending
on chart log recording rate), download the detector event log to a PC from the
RS-232 port using a serial cable.
Transport time verification
The maximum transport time verification test is the measure of the amount of
time it takes for the detector to respond to smoke that enters the pipe at the
sampling point furthest from the Detector. The results of this test and the
calculated maximum transport time from PipeCAD must be recorded on the
checksheet. Measured transport time less than the calculated time is acceptable.
To measure the maximum transport time of the system:
1. Determine the furthest sampling point from the detector.
2. Allow test smoke to enter the pipe at the furthest sampling point.
3. Record the amount of time for the detector to respond. This is the actual
maximum transport time.
Gross smoke testing
The gross smoke test is a measurement of the amount of time elapsing from the
activation of the smoke generating medium, until Pre-Alarm and Alarm is
reached. This test should be repeated at least three times with consistent results.
Recommended smoke generating medium is simulated smoke or wire burner.
