A.6. LASER POINTER
During commissioning, activation of the laser pointer makes it possible to check that the reflector has been positioned
correctly in relation to the E / R.
If the zone indicated by the laser beam is more than 5 cm away from the reflector, adjust the position of the E / R,
using the corresponding screws to bring the point indicated by the beam closer to the reflector.
To activate the laser pointer: press the button and hold for more than a second, then release.
To deactivate the laser pointer: press the button again. If the button is not pressed, it will deactivate automatically after
a delay of 20 minutes.
A.7. AUTOMATIC CALIBRATION
Automatic calibration consists of defining and storing the parameters inside the detector, based on:

The distance between the E / R and the reflector,

The position of the reflector in relation to the E / R.
Automatic calibration starts automatically when the laser pointer is deactivated after the button is pressed; the
automatic calibration sequence is as follows:
During automatic calibration the barrier may trigger the alarm for the conventional zone to which it is
connected if it is powered from that zone.
Indicator light Step description
Flashing green Automatic calibration in progress
Steady green Automatic calibration performed correctly
Flashing orange Automatic calibration error (1)
1. In this case, start a new automatic calibration process by pressing the button; take care not to block the infrared
beam.
Note: If the orange light flashes when you start the automatic calibration process (when you press the button to
deactivate the laser pointer), make sure the detector and reflector are not exposed to direct sunlight.
Note: If the orange light flashes after a succession of green pulses, carry out E / R alignment again so that the point
indicated by the laser beam is on the reflector.
A.8. ALIGNMENT CHECK
This check allows you to make sure there are no parasitic reflections which could compromise detector operation.
The detector automatically enters alignment check mode after an automatic calibration procedure has been carried
out successfully. In this case:
1. The indicator light flashes red,
2. Completely mask the surface of the reflector with a non-reflective object (packaging cardboard, for example) for at
least 10 seconds,
3. While the masking is in place, the indicator light may assume one of the two following statuses:
Indicator light Meaning
Steady green Acceptable reflection level
Flashing red Excessive parasitic reflection level (see note)
4. Exit alignment check mode by pressing the button or by restarting the control panel.
Note: While the reflector is masked, it is wise to search for reflective objects along the route of the infrared beam and
cover them in order to obtain the green indication. After this search, there are two alternative solutions:

Cover the reflective objects permanently,

Move the detector.
Caution:

Take all necessary precautions to avoid activating the evacuation process or ordering activations
accidentally.

This check does not in any way replace actual standardised tests, but can be used during servicing test
procedures.
Note:
If the indicator light does not turn red to indicate an alarm within 40 seconds, disconnect the detector from the
power supply for 2 minutes and repeat the commissioning procedures.
