2 OPAL Plus SATEL
The OPAL Plus detector detects motion in the protected area. It is designed for outdoor use.
This manual applies to the detector with electronics version D. The detector meets the
requirements of the EN 50131-2-4 standard for Grade 2.
The Grade 2 certificate applies to the indoor use. The outdoor use of the
detector (despite full Grade 2 functionality) is not covered by the certificate
(there is no standard for the outdoor detectors).

Weatherproof enclosure featuring a very high mechanical strength.
2. Description
The alarm will be triggered when infrared sensor (PIR) and microwave sensor detect motion
within a time period shorter than 4 seconds.
Anti-mask feature
Detection by the microwave sensor of an object moving at a distance of 10-20 centimeters
from the detector is interpreted as an attempt to mask the detector and results in activation of
anti-mask output for two seconds. Objects permeable to microwaves, but isolating the
infrared radiation are not detected by the anti-mask feature.
The anti-mask feature meets the EN 50131-2-4 requirements.
Dusk sensor
Figure 1 shows the way the dusk sensor operates. On the timeline the T time delay is
presented (in operating mode T=3 min, in configuration mode T=3 s). Illustrated with the
letter H light intensity hysteresis and time delay make the sensor immune to short and
