5. 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
learns and acclimates to the protected environment and sets up appropriate day and
night sensitivity settings.
6. Reconnect the detector to the fire control unit, if applicable
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. Investigate and
correct any condition that cannot be accounted for.
Suction pressure verification
Sample hole suction pressures can be measured and recorded on the checklist for
future reference using the steps below.
To perform a pressure test:
1. Attach a flexible hose onto the suction side of the magnehelic pressure gauge.
2. Place the hose against the sampling hole and hold it in place.
3. Hold the gauge in the plane in which it was calibrated and read the suction pressure
from the gauge as shown in Figure 13 below.
