“Antimasking” function
The detector is equipped with an active IR anti-masking function to protect the
PIR. It emits a tampering signal within 3 minutes.
The output of this function is the MASK terminal block.
In a standard configuration, this terminal block can be connected to a 24h active
line or to a control unit input appropriately programmed to send fault messages.
When the detector identifies a masking attempt, the LEDs flash simultaneously
until the masking condition is resolved.
To enable the correct operation of the masking detection system (Anti-masking),
allow the detector to study and analyse the environmental conditions of the area
to be protected. This procedure is mandatory to guarantee the correct operation
of the anti-masking channel.
Follow the procedure below:
1.
Make the connections to the detector terminal box, leaving the DIP switch 5
(table 3, R) set to OFF.
2.
Once powered, close the cover and run all the detection tests required.
3.
Open the cover and set the DIP switch 5 to ON.
4.
Close the cover immediately (maximum within 10 seconds).
5.
Stay at least 1 meter from the front part of the detector for at least 4 min-
utes.

•
OFF set - LEDs enabled
•
ON set - LED disabled

INSTALLATION
WARNING
•
The wall does not have any pronounced depressions or protrusions.
•
Install the detector on rigid surfaces, free of vibrations.
•
Avoid to fix the detectors near to heat sources or at direct sunlight.
•
Avoid electromagnetic energy reflection on wide surfaces such as mirrors, metal
walls, etc.
•
Avoid to fix the detector in front of fluorescent lamps or in proximity of them.
•
Connections shielded cable is suggested and one cable per detector is preferred.
F
If the detector is installed on a tilted wall, or pole, the detection range will be
reduced.
Both, upward as downward.
