6. When the detector is still in FastLearn mode, exit the Programming Mode on
the display by pressing <RESET> and set the detector into Demonstration
Mode (see “Detector programmable functions” on page 42 for details). To do
this, press and hold down the <RESET> button and simultaneously depress
the <TEST> and <ISOL> buttons. The text display will then display “Demo
mode” and the time and date.
7. Wait for the FastLearn to finish (when the legend FastLearn is no longer
displayed and the “rolling” LED indications stop sequencing) and perform any
necessary smoke tests, ensuring that the detector reacts appropriately, and
let the smoke fully dissipate.
8. 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 while ClassiFire acclimates to the protected
environment and sets up appropriate day and night sensitivity settings.
Precommissioning preparation
Commissioning is recommended 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
RS232 port using a serial cable.
