In this case,
–
Set the range to
position Y
.
The range will then be
8 m
, which is
shorter than the ideal range but might
reduce the risk of false detection.
–
Perform an operating test to confirm.
Detection should -take place in zone (a)
and not zone (b).
Environ 8 m position B
Environ 12 m
a
b
Approx. 8 m
Position B
Approx. 12m
2.
The detector has a multi-level detection zone
(side view). A heat source located outside the
detection zone may cause a false alarm due to
reflection off the ground. Examples of reflective
surfaces: puddles, damp road, smooth surface,
tarmac road, etc.
Of course, the reflection rate off the ground is
not 100%, but if the heat source is powerful
and/or the reflection rate is high, the detector’s
range will increase to become larger than
desired, thus creating the risk of false
detection. Select the range depending on the
characteristics of the ground at the installation
site.
Testing detector operation with the system
1
Close the cover, replace the
end cap and tighten the screw.
Arm the alarm system.
2
Wait for 2 minutes before passing in
front of the detector.
Detector operation must comply with the choices
in the table on page 6.
