GENERAL
INFORMATION
Ademco
has taken the next step on motion detector
technology
with the QUEST
2000,
Ademco's
Image
Processing detector.
The QUEST 2000 is a "thinking" detector which uses a
combination
of two diverse
methods
of detection
to
improve
false alarm
immunity.
The passive
infrared
detector provides 22 zones of wide angle coverage with a
range of 40 feet (12.2 m). In addition, there is a "look-
down" zone that provides protection in the area close to
the mounting wall. A microwave detector provides alarm
verification.
The PI R optical system divides the area into a seties of
protected zones. A dual element PIR sensor measures the
level of infrared energy in each zone. The microwave
system provides a volumetric coverage pattern. When an
intruder enters the combined PIRlmicrowave
protective
pattern, PIR and microwave signals will be generated at
the same time and the detector's relay will repofi an alarm.
The QUEST 2000 includes a microprocessor with analog-
to-digital conversion which provides:
. Dual technology
signal processing
for immunity to
environmental disturbances and reduced false alarms.
,-
Ademco image processing
of 256 different environ-
mental contrition levels.
. Adaptive microwave signal processing for false alarm
immunity.
. 40 ft (12m) x 50 ft (15m) range with "look-down" zone.
Adjustable microwave range with potentiometer.
. Rejection (with digital notch filter) of fluorescent light
disturbances.
. Trouble output. Unit pedorms self-test and repotis a
failure. Unit continues to operate as PIR only.
. Alarm LED local and remote disable.
. Dgital pulse count and pulse recognition provides false
alarm immunity in harsh environments.
True digital temperature comp6nsafion.
. DIP switch selectable functions: walk test, Pulse Count
3 (PIR), Alarm LED disable.
. Ademco

Does not require any optics
adjustment.
* Low current drain, which allows for extended power

COVERAGE
AND LOCATION
CONSIDERATIONS
Combined protective pattarns are shown in Diagram 1, for
a nominal mounting height of 7.5ft (2.3m).
Tha microwava detection pattern shown in Diagram 1
repreaenta coverage in open space. In practical applica-
fiona, when the detector ia bounded by ceiling, floor, and
walla, reflections occur and the device provides volumetdc
coveraga.
Selecting
a Mounting
Location
The detector responds to changes in energy which occur
when an irbtrudarmoves into the combined protection pat-
tern. Best t:ovarage will ba obtainad if tha mounting site is
selected so that the likely direction of intruder motion is
genarally ;tcross the pattern and angles slightly toward the
detector (see Magram 1),

lnstallatio,n Hints
The
detector
is remarkably
resistant
to false
alarm
hazards, but the following racommendafions
should be
obaewed:
.
.
.
.
Select ?I mounting haight approximately
7.5ft (2.3m)
above the floor.
Do not nlount on an unstable sutiace. Locate the unit on
a sturdy inside wall whenever possible. Avoid sources of
vibmtion such as loose fitting doors and walls that shaka
whan heaq traffic exists.
Do not install on or close to metal structures such as
metal door framas, shelves, ate.
Do not include space haatars in the protective pattern
whenavt?r possibla, to avoid rapid temperature changes
and vib~sfion from fans.
