Paradox developed the NVX80 to provide superior anti-masking capabilities. The combined Active IR and MW
anti-mask technologies detect an extensive range of materials placed or sprayed on the lens, and object placed
in close proximity of the lens, movement within close range of the unit and the degradation of the lens by dirt or
dust by 50% from factory-set levels. The NVX80 anti-mask technology protects the detector from a wide range of
materials; including but not limited to clear lacquer, aluminum foil, cling wrap, clear adhesive tape, and spray paint.
If an obstruction is detected and remains for a predetermined time, an anti-mask event will be noted. If the object
causing the obstruction, masking or blocking, is removed before the predetermined time has been reached an
alarm will not be triggered or cause an effect on the relays.
Active IR detects any objects blocking the lens in close proximity of the unit; 0 – 30 mm / 0 - 11.8 in. The anti-mask
response time can be set at :30, :60, and :120 seconds. The response time will correspond to the time needed for
the masking to persist until an alarm is triggered. During the response relay time, 3-5 seconds after detection of an
obstruction, a blue frame will be displayed. This will allow for an object accidentally blocking the lens to be removed.

Action
Select sensitivity to environmental conditions: indoor for high sensitivity
or
outdoor for reduced sensitivity
Choose from 30, 60, 120 seconds to define as the detection time required until an
anti-mask event is triggered
A blue frame appears 3-5 seconds after masking starts and an anti-mask event is
triggered after the selected time frame has passed
Initiate an anti-mask calibration process
Test the anti-mask functionality
This code is generated after the last anti-mask calibration process and may be
required when communicating with distributor support
