1. SENSITIVITY SELECTOR
To adjust the sensitivity , first remove the lens (as this covers the sensitivity
switch).See the procedure on 4-5.
This switch may be used where:
A) Turn the switch to “L” (Low) position when the detector is installed in a
hostile area, which may cause a false alarm.
It may be used in situations where the area of coverage may be small or
narrow.
Where small animals may be present or where there may be sudden
temperature changes.
B) Turn the switch to “H” (High) position when greater sensitivity is required,
example (in Long Range applications exceeding 67ft (20m), areas with
high temperatures which reduce the temperature difference between the
target and background, or when the detector is mounted at higher than
9ft (2.7m).

The Detection Mode can be switched to either “Standard” or “Special” mode
depending on the environmental conditions of the installation.
*Ensure that the “STD” position is used when the “Long” range lens is
fitted.
STD : For normal applications.
SP : For use in hostile areas where there may be movement
from small animals or other objects such as fax machines
or curtains.
When the “SP” is selected, the detector’s
sensitivity may seem sluggish. It is
therefore important to always conduct a
walk test to ensure that the desired
coverage is given.
Alarm Memory ( CX-502V , CX-502AM only )
This function is used to indicate if the detector was activated while the
panel was armed. It will cause the red LED on the Detector to illuminate
once the panel has been disarmed.
Initial Alarm Memory ( CX-502AM only )
When several detectors are on the same loop with the alarm memory
function, after disarming:
1) The first detector to be activated flashes its LED.
2) On any subsequent detectors that became activated the red LED
will stay on.
• Alarm Memory and Initial Alarm Memory will not activate while system is disarmed.
• After Alarm Memory and Initial Alarm Memory latches, Alarm Output operate normally
during armed period.
The Anti-Masking function protects the detector’s lens
from being covered by either an object or from hostile
substances such as spray, therefore allowing it to detect
to its specifications.
The Self-Check function is an onboard circuit, which checks
the operation of Detector at regular 5 hour intervals. This
ensures that the unit is always Working correctly.
Trouble output: (TO)
This output activates if there is either an Anti-masking
detection or a Self-Check problem.
Switching the Trouble Output
In the Event of either a Masking or SelfCheck problem, then the unit may be set
to either activate just the Trouble output
or the Trouble and the Alarm outputs.
Using DIP Switch 4 makes this selection.
LED display
As well as the trouble output, the yellow LED
on the detector will also display the trouble
condition.
This function is displayed only when the LED ON / OFF
switch or the Remote Control from the DL terminals is
“ON” while the system is disarmed.
Anti-Masking
If an object is placed within 10cm in front of the detector, for a period of more
than 10 seconds then the Anti-Masking circuit will activate, triggering the
Trouble output.
When the object is removed away from the lens, and then the Anti-Mask
circuit will automatically be reset after one second, switching off the LED
indication as well as the Trouble output.
Caution on Installation.
Since the accuracy of the anti-masking detection is very critical, please take note of
the following points.
1) Installation.
Avoid locating the detector where any objects can be within 1 meter from the
detector such as by doors, hanging signs or curtains. Also avoid locating the
detector where it may be in direct or reflected sunlight.
2) Powering up the Detector.
This type of detector sets its optimum level of performance automatically during
warm-up period. This enables it to be set up correctly to provide reliable performance with the minimum of fuss.
To ensure that this setting up is carried out properly, please follow the following
instructions carefully.
A)- Keep at least 1 meter away from the detector when first applying the power
to the unit.
B)-Keep at least 1 meter from the detector clear of any objects when first apply-
ing the power.
Testing the Detector
1) Ensure that all of the above procedures have been carried out, then apply power to
the detector.
2) The detector will go through a warm-up period during which the display LED’s will
blink. (The Anti-Masking circuit will also start to set itself to its optimum level at this
point).
3) When the LED’s stop blinking the detector is set and ready for use.
(If the LED’s continue to blink then refer to the trouble shooting section).
4) Place an obstacle such as hand within 10cm in front of the detector for more than 10
seconds.
5) The detector works correctly if the yellow LED starts to blink slowly, indicating that
it has been masked.
6) Remove the obstruction and the yellow LED should stop flashing. This completes the
set up procedure.
