Dual-Technology Microwave/PIR Intrusion Detector

,1752'8&7,21

DUO 200 is a state-of-the-art microcomputer controlled dual­technology intrusion detector. Its operation is based on two
physical phenomena - the infr ared (IR) radiation emitted by the
human body and the Doppler frequency s hift caused by a pers on
moving in a microwave (MW) field. The IR and MW t echnologi es,
when combined in a single det ector, complement each ot her to
assure the most r eliable detection and immuni ty to false alarms.

The superiority of the DUO 200 over other dual detectors has
been achieved by the advent of the Tr ue Motion Recognition™
algorithm (patents applied for). This advanced motion analysis
method provides the DUO 200 with the ability to distinguish
between the true motion of a human body and any other
disturbances which invariably cause false alarms.

Another unique feature of the DUO 200 is the MW Motion
Simulator circ uit (patent s applied f or), whi ch si mulates t he effect
created by a human body moving in the MW fiel d. The si mulation
routine is car ried out periodically for the purpose of self -testing,
supervision and assurance that the MW detector operates
properly.

A few important rules must be observed before selecting a
mounting location:

A. Microwave radiation passes through glass and non-metallic

walls. Be sure to adjust the MW range so that it does not
exceed the room limits, or else a rotating ceiling fan in the
next room, or moving traffic along the out er side of the wall
will cause the MW detector to alarm.

B. Large reflecting objects (especially metals) within the

coverage area can dist ort the microwave detector's coverage
pattern.

C. Although the DUO 200 is extremely immune to false alarms, it

is recommended to avoid installation in a room with very
strong air tur bulence or close t o high-power electrical cables.

D. If two DUO 200 units are installed in the same room or on

opposite sides of a shared wall, they should not face each
other and must be mounted at l east 2 meters apart .

E. For best performance at high ambient temperatures, it is

recommended to aim the unit towards the cooles t place i n the
protected area.

F. Always mount t he unit on a f ir m and st abl e s ur fac e at a hei ght

that renders optimum coverage of the protected area.
Increasing the vertic al angle at a certain height will increase
the coverage range.

G. Do not install the DUO 200 i n places where one of the t wo

detector circuits alarms constantly or intermittently, due to
environmental interference.

C. Selec t the mounting location in accordance with the guidelines

in Section 3.1.

D. Temporar ily remove the PC board from the base. Tak e care

not to lose the fas tening screw.

E. Use the base as a template for marking the drilling points.
F. Drill mounting holes and insert masonry anchor s if required.
G. Pass the wires through the punched-out wiring inlet(s) and

mount the base in place using two screws .

H. Seal all openings in the base wit h RTV to pr event i ns ec ts f rom

entering the unit.

I. Remount the PC board and secure it with its vertical

adjustment scr ew.

The BR-1 is a general purpos e swivel bracket used for vert ical
and horizontal positioning of the DUO 200. With the BR-1, the
unit can be tilted down from 0° to -30° and swivell ed 45° left or
right (see Fig. 4).

The BR-2 is a swivel bracket kit for room corner installations,
consisting of the BR-1 and a corner adapter. The BR-3 i s a swivel
bracket kit for ceiling instal lations. It consi sts of the BR-1 and a
ceiling mounting adapter.

The unit can be installed directly on the wal l or in a room corner
using the mounting knockouts. Optional swivel brackets permit
greater flexibility when adjusting the coverage area (Secti on 3.8).

A. Loosen and remove the screw at the bottom of the c ase (see

Figure 1) and then take t he cover off.

B. Punch out the appropriate mounting and wiring knockouts in

the base.

Figure 3. Printed Cir cuit Board Layout

Notes:

1. For wall surface mounting, use the two elongated
knockouts at the middle of the bas e. For c or ner mounting, us e
two diagonally opposite knoc kouts at the angled sides of the
base (see Figure 3).

2. To route the wiring t o a lower conduit, use the t wo wiring
knockouts at the bottom of the base (see Fi gure 3). To r oute
the wires under the base towards t he ceiling, use the wiring
channel and its associated knockout.

Figure 4. Optional Swivel Brackets

Caution! When a swivel brac ket is used, the effec tive detection

range may differ from that i ndicated in Table 3 (see Para. 3.8).

Connect wires to the terminal block in the following or der:

Terminal: TAMP (tamper switc h)
Connect to: A normally closed 24-hour tamper zone of the

control panel.
Details: When the cover is r emoved, the t amper swit ch cont acts
open.

Terminal: NC (alarm relay)
Connect to: Normally closed burglar protection zones of the

control panel.
Details: Upon alarm or power failure, the out put relay's normally
closed contacts open.

Terminal: TRB (trouble output)
Connect to: 24-hour trouble zone, paral lel to an E.O.L. resist or

(see Figure 5).
Details: The TRB open collector output will be grounded upon
detector malfunc tion, causing disturbanc e in the trouble zone of
the associated alarm system.
