GENERAL INFORMATION
The Quest 2235 and Quest 2235C (with Form C relay)
Microwave/PIR motion sensors offer next-generation
performance with technology advances in many areas,
including optics and signal processing. Unmatched levels of
operation are assured with the following advanced features:
•
Microprocessor-based C
3
signal processing (Cross-Channel
Correlation) instantaneously correlates data from both the
PIR and microwave channels. No longer are there separate
PIR and microwave decisions- only a single, total unit
alarm based on multi-dimensional analysis of
simultaneous data from both channels.
•
Split-Zone Optics technology improves discrimination
between human and animal targets.
•
Robust pet immunity to 100lbs over a range of mounting
heights without sacrifice to detection.
•
Accu-Trak environmental test feature allows the installer
to check for environmental disturbances on both the PIR
and microwave channels at the same time.
•
Automatic adaptation to environmental disturbances.
•
Rejection (with a patented digital notch filter) of
fluorescent light disturbance.
•
Continuous supervision of both PIR and microwave.
•
Advanced dual-slope temperature compensation assures
optimal detection.
This detector is shipped with its standard pet immune lens
installed to provide coverage of 35ft x 45ft. If other coverage
patterns are desired, please consider the following alternative
products:
• Quest 2220: 20 ft x 25 ft with 100lb pet immunity
• Quest 2260: 60 ft x 75 ft
Optional swivel-mounting brackets are available under part
number 998SB and Quest-SB2, but are not recommended for
installations with pets.
NOTE: To use the optional Look Down Zone, the masking
material must be removed. Once the masking material has
been removed, the Look Down Zone may be removed again by
taking out the Look Down lens (see Figure 3 for location). Do
not remove the masking material for pet applications.
COVERAGE & LOCATION CONSIDERATIONS
Combined protective patterns are shown in Figure 1 for a
nominal mounting height of 7.5 ft (2.3m). The microwave
detection pattern shown in Figure 1 represents coverage in
open space. In practical applications, when the detector is
bounded by ceiling, floor, and walls, reflections can occur.
SELECTING A MOUNTING LOCATION
The detector responds to changes in energy that occur when an
intruder moves into the combined protection pattern. Best
coverage will be obtained if the mounting site is selected so
that the likely direction of intruder motion is generally across
the pattern and angles slightly toward the detector.
