3.
Subject the detector to a flow of warm air at a temperature of
between 65 ˚C and 80 ˚C as follows (this requirement can be
met by some domestic hair dryers).
a.
Start the warm airflow and check that temperature is
correct and stable.
b.
From a distance of approximately 5 cm, direct the
airflow at the guard protecting the thermistor for up to
30 s. The detector will signal an alarm by continuous
illumination of the LED.
c.
Upon alarm, immediately remove the heat source.
4.
Reset the detector from the control and indicating equipment.
5.
Check that the detector LEDs are off and the control and
indicating equipment returns to the quiescent condition.
Remote Indicator (where fitted)
Check that the indicator illuminates at the same time as the
detector LEDs.
Output Relay (where fitted)
1.
Follow Heat Detector procedure step 3.
2.
Monitor the output relay for activation.
3.
Reset the detector from the control and indicating equipment.
4.
Monitor the output relay for reset to its quiescent setting.
Auto-Reset (where fitted)
1.
Follow Heat Detector procedure step 3.
2.
Monitor that the detector automatically resets.
The auto-reset will typically reset the detector within 30 s of the
removal of the heat source.
Final Conditions
Ensure all the alarm signal services, releasing devices and
extinguisher systems disabled for the commissioning are returned
to their previous condition.
