DUO 220 / DUO 220 AM
Dual Technology Microwave/PIR Intrusion Detectors
Installation Instructions
1. INTRODUCTION
The DUO 220 (MW/PIR) and DUO 220AM (MW/PIR/antimasking) are state-of-the-art, microcomputer controlled dualtechnology intrusion detectors. The PIR and MW technologies,
when combined in a single detector, complement each other to
assure the most reliable detection and immunity to false alarms.
The superiority of the DUO 220 series over other dual detectors
has been achieved by the advent of the True Motion
Recognition™ algorithm (patented). This advanced motion
analysis method provides the DUO 220 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 220 is the MW Motion
Simulator circuit (patents applied for), that simulates the effect
created by a human body moving in the MW field. The simulation
routine is carried out periodically for self-testing, supervision and
assurance that the MW detector operates properly.
In addition, the pyroelectric sensor and its circuitry are tested at
regular intervals by application of a short-duration heat pulse. If they
do not react properly, a trouble alert is initiated.
To complement the detection pattern provided by the front lens,
the DUO 220 is fitted with a down looking lens at the bottom part
of the front cover. The purpose of this lens is to prevent access to
the detector by sneaking below it.

3. INSTALLATION
3.1 General Guidelines
A few important rules must be observed before selecting a
mounting location.
• 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 outer side of the wall will
cause the MW detector to alarm.
• Large reflecting objects (especially metals) within the coverage
area can distort the microwave detector's coverage pattern.

Coverage Pattern
•
•
•
•
Although the DUO 220 is extremely immune to false alarms, it
is recommended to avoid installation in a room with very strong
air turbulence or close to high-power electrical cables.
If two DUO 220 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 least 2 meters apart.
For best performance at high ambient temperatures, aim the
unit towards the coolest place in the protected area.
Always mount the unit on a firm and stable surface at a height
that renders optimum coverage of the protected area.
•
•
Increasing the vertical angle at a certain height will increase
the coverage range.
Do not install the DUO 220 in places where one of the two
detector circuits alarms constantly or intermittently, due to
environmental interference.
Special advice to DUO 220AM users: It is desirable to mount
the unit in locations where inadvertent approach to less than
1 m (3 ft) from the detector is unlikely to occur.
3.2 Direct Mounting
The unit can be installed directly on the wall or in a corner using
the mounting knockouts. Optional swivel brackets permit greater
flexibility when adjusting the coverage area (see Para. 3.3).
A. Loosen and remove the screw at the bottom of the case
(Fig. 1) and then take the cover off.
B. Punch out the appropriate mounting and wiring knockouts in
the base.
Note: For wall surface mounting, use the two elongated
knockouts at the middle of the base. For corner mounting, use
two diagonally opposite knockouts at the angled sides of the
base (Fig. 3).
Figure 4. Optional Swivel Brackets
3.4 Wiring
Connect wires to the terminal block in the following order (Fig. 5):
Figure 5. Terminal Block Wiring
Terminal: TAMP (tamper switch)
Connect to: A normally closed 24-hour tamper zone of the
control panel.
Figure 3. Printed Circuit Board Layout
Details: When the cover is removed, the tamper switch opens.
C. Select the mounting location in accordance with the
guidelines in Para. 3.1.
D. Temporarily remove the PC board from the base. Take care
not to lose the fastening screw.
E. Use the base as a template for marking the drilling points.
F. Drill the mounting holes and insert masonry anchors 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 with RTV to prevent insects from
entering the unit.
I. Remount the PC board and secure it with its vertical
adjustment screw.
Terminal: NC (alarm relay)
Connect to: Normally closed burglar protection zones of the
control panel.
3.3 Optional Swivel Brackets
Terminals: 12 V (+) and (–)
Connect to: A power source within the range of 9 to 16 VDC.
Take care not to reverse the polarity.
The BR-1 is a general purpose swivel bracket used for vertical
and horizontal positioning of the DUO 220. With the BR-1, the
unit can be tilted down from 0° to -30° and swiveled 45° left or
right (see Fig. 4).
The BR-2 is a swivel bracket kit for room corner installations. It
consists of the BR-1 and a corner adapter.
The BR-3 is a swivel bracket kit for ceiling installations. It consists
of the BR-1 and a ceiling mounting adapter.
Caution! When a swivel bracket is used, the effective detection
range may differ from that indicated in Table 3 (Para. 5.1).
Details: Upon alarm or power failure, the output relay’s normally
closed contacts open.
Terminal: TRB (trouble output)
Connect to: 24-hour trouble zone, parallel to an E.O.L. resistor
(see Figure 5).
Details: The TRB open collector output will be grounded upon
detector malfunction or upon masking (DUO 220AM), causing
disturbance in the trouble zone of the associated alarm system.
Alternative: a buzzer or an interface relay may be connected
across the TRB output and the 12 VDC (+) terminals.
Details: It is advisable to connect the power source only after all
other connections have been completed and rechecked. Disconnect the AC mains from the alarm control panel and verify that
the voltage supplied to the detector is above 9 Volts with the
backup battery as the only power source.
IMPORTANT: To comply with CE safety requirements, connect to
CE-approved control panels with current-limited DC output.
Note: Use RTV to seal the base opening(s) to prevent insects
from entering the detector.

3.5 The Power-up Process
After connecting the (+) and (–) terminals to the power source,
the DUO 220 starts a 60-second warm-up period, indicated by
alternate flashing of both LEDs.
Caution! If the alternate flashing of the LEDs does not stop within
60 seconds, a failure has been detected by the self-test circuitry
or, if you are dealing with DUO 220AM, the unit may be masked
(see Para. 3.6).
3.6 What Happens in Case of Masking?
If an attempt is made to stick masking material over the lens or
put a masking object close to the lens (DUO 220AM only), a
trouble alert will result about 60 seconds after masking:
• The red and green LEDs will flash alternately;
• The TRB output will pull to ground and will remain grounded
until the detector is reset (see Para. 5.6 for procedure).
4. INDICATORS AND SELECTORS
4.1 LED Indications
The two LEDs (Fig. 1) are used to signal various alarm and
trouble messages as shown in Table 1 below:

Initial warm-up routine (stops 60
seconds after power up).
Notes: 1. During walk testing, the first LED to respond is the
green one. It illuminates steadily (MW detection) or flashes (PIR
detection), depending on which one of the two detectors
discovered the motion first. Upon subsequent discovery of the
motion by the other detector, the green LED will go off and the
red LED will illuminate (alarm).
2. If the green and red LEDs continue to flash beyond the warmup period, a malfunction or masking has been diagnosed.
Replace the unit without delay.
4.2 Mode Selector
The DIP switch mode selector is mounted on the unit’s PC board
(see Fig. 3). It controls four functions as demonstrated in Fig. 6
and as detailed in Table 2.

5. Initial Adjustments
5. ADJUSTMENT AND TEST
5.1 Adjusting the Vertical Angle
The vertical adjustment scale for the PIR detector is located at
the lower left edge of the PC board (see Figure 3). A screw in the
middle of the board allows fast and easy adjustment from +2° to
–12°. All DUO 220 units are pre-adjusted in the factory to –5°.
Table 3 below provides recommended vertical adjustment angles
for various combinations of mounting height and coverage range.
A. Use Table 3 to find the optimum angle for the coverage you
require. For example, if a coverage range of 9 m (30 ft) is
required and the detector is installed at a height of 1.8 m (6 ft)
above the floor, set the vertical angle to -6°.
Table 3. Vertical Angle Adjustment
For faster catch performance, shift SW-1 to OFF. In this position,
only one motion event is required to trip the PIR detector.
5.3 PIR Walk Test
A. Rotate the MW RANGE control all the way towards MIN.
B. Verify that DIP switch SW-3 is set to ON (the green walk-test
LED is enabled).
C. Mount the front cover in place.
D. Walk into the detector's field of view at the expected far edge
of the coverage area. The green LED should flash for up to 5
seconds each time your motion is detected.
Note: If the green LED illuminates steadily, your motion has
been detected by the MW detector.
E. If PIR detection is not obtained at the far end of the coverage
area, remove the front cover and re-adjust the vertical angle.
Replace the cover and retest.
5.4 MW Walk Test
B. Loosen the vertical adjustment screw, slide the PC board
along the vertical slot until the pointer indicates the required
angle on the scale. Then tighten the adjustment screw firmly.
Note: Since the adjustment screw also fastens the PC board
to the base, vertical adjustment should be repeated if the PC
board is replaced.
5.2 Setting the Motion Event Counter
If you wish to set the PIR detector for maximum false alarm
immunity, shift DIP switch 1 (SW-1) to ON. In this position, two
consecutive motion events are required to trip the PIR detector.
DE1823
A. Remove the front cover.
B. Verify that the MW range control is set to MIN and DIP switch
SW-3 is set to ON (the green walk-test LED is enabled). Close
cover.
C. Start by moving into the coverage area at the far edge. The
green LED should light steadily for up to 5 seconds each time
your motion is detected.
D. If your motion was not detected at the far edge of the
coverage area, advance the MW RANGE control slightly
toward MAX and try again until your motion is detected
reliably at the far edge.
Caution! The MW detection range must not exceed the far
edge of the desired coverage area.
Attention! To assure proper function of the detector, the
range and coverage area should be checked at least twice a
year. Furthermore, it is recommended to perform a walk test
at the far end of the coverage pattern to assure an alarm
signal prior to each time the alarm system is armed.
E. Walk across the coverage area at various ranges and verify
that your motion is consistently detected.
Note: If PIR trips interfere with your test, disable the PIR by
inserting a small piece of cardboard in front of the sensor.
5.5 Alarm Walk Test
A. Set DIP switches SW-2 and SW-3 to ON (both LEDs are
enabled).
B. Install the front cover in place.
C. Walk across the detector’s field of view in different directions,
at various distances from the detector, and verify proper
detection throughout the detector's coverage area (the red
LED will illuminate for 2 to 3 seconds).
D. When done, remove the cover and set DIP switches SW-2
and SW-3 to OFF to prevent unauthorized people from tracing
the coverage pattern.
E. Remount the cover and fasten it to the base using the small
screw at the bottom.
5.6 Resetting after Trouble (DUO 220 AM)
In case of trouble alert, proceed as follows:
• Search for masking material on the lens or a masking object in
front of the lens and remove them, if found.
• Reset the detector by walk testing - cross its field of view at the
far end, causing it to alarm several times.
If everything is back to normal, the red and green LEDs should
stop flashing, and the TRB output should revert to the opencircuit state (disconnected from the ground).
Note: If walk testing does not cause the trouble alert to stop,
recheck for masking. Once masking is ruled out, the trouble is
probably due to defective PIR or MW circuitry. Replacing the
detector unit will solve this problem.
6. SPECIAL NOTES
Although this detector is a highly reliable device, it does not
guarantee complete protection against intrusion. Even the most
sophisticated detectors can sometimes be defeated or may fail to
warn because:
A. The detector will not function if the DC power supplied to it is
incorrect or improperly connected.
B. Detection is confined to the area covered by the detection
pattern as adjusted by the installer.
C. A PIR detector does not provide full volumetric coverage of
the protected area. It can only detect motion that disturbs the
sensitive beam array spread within the protected space.
D. Motion will not be detected by PIRs if it takes place behind
closed doors, floors, walls, ceilings, glass partitions, windows
and shutters.
E. The detection ability of the PIR detector may be reduced by
malicious masking or by spraying various materials on the
optical lens. Mechanical tampering may also damage the
optical system.
F. As the ambient temperature of the protected area approaches
the range of 32°C - 40°C (90°F -105°F), the PIR detector's
performance can decrease.
G. The protection pattern provided by the microwave detector
may be altered by metal objects or foil-covered insulation.
H. Even the most reliable electrical devices, including this
detector, may go wrong because of an unexpected failure of a
component part.
The above list includes the most common reasons for failure to
detect intrusion, but it is by no means comprehensive. It is
therefore recommended that the detector and the entire alarm
system be checked weekly, to ensure proper performance.
An alarm system should not be regarded as a substitute for
insurance. Home and property owners or renters should be
prudent enough to continue insuring their lives and property. This
