Visonic DUO 220 Installation Instructions

DUO 220 / DUO 220 AM
Dual Technology Microwave/PIR Intrusion Detectors
1. INTRODUCTION
The DUO 220 (MW/PIR) and DUO 220AM (MW/PIR/anti-
masking) are state-of-the-art, microcomputer controlled dual-
technology 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.

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.

Installation Instructions
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.

•
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.
