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

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

walk test faature

for faster

installation.

These additional conventional features are included:

. Dust etement

pyroatactric

PIR sensor and

Fresnel

ODfiCS.

. Superior

lens design.

Does not require any optics

adjustment.

* Low current drain, which allows for extended power

sourca standby batte~ life.

12VDC operation.

. Wall and cornar mounting brackat providad.

Optional swival bracket is availabla.

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.
