SILVER is an advanced dual technology digital motion detector with dual
element PIR sensor and microwave sensor. Its dual-tech design, digital motion
detection algorithm and temperature compensation function provide high immunity
to false alarms and interference, even in areas where adverse or rapidly
changing conditions prevail, e.g. in the vicinity of fireplaces, in boiler
rooms, garages, or in places where drafts frequently occur. Independent, smooth
control of both sensors makes it possible to perfectly adjust the device
performance curve to requirements of the user and the protected premises.
Moreover, the detector can operate in two modes of detection: basic, in which
an alarm will occur after motion has been simultaneously detected by both
sensors, or advanced, in which an alarm will also be triggered after
a certain number of violations of the microwave channel, making it
possible to detect e.g. an attempt to enter the protected zone by an intruder
covered with body heat absorbing material. An important feature of the device is
so-called anti-masking: the microwave sensor detects any attempt to mask or
cover the detector, which would disturb its proper functioning. The detector
has a function of supply voltage level and signal channel status control,
tamper protection against enclosure opening, and two-color LED indicating
motion detection / alarm. It is also provided with EOL resistors for easy
installation and connection to the alarm system. SILVER complies with the EN
50131 requirements for Grade 2.
The main task of the detector is to detect violations in the protected
area. However, it can also be used to implement the building automation
functions. When the alarm system is not armed, the detector can control turning
on the lights, opening or closing the doors, etc.
