1. INTRODUCTION
. INTRODUCTION. INTRODUCTION
. INTRODUCTION
The NEXT DUO is a digital, microprocessor-controlled MW / PIR
detector that can be adapted to the size of the protected area by
use of a model selector. A different digital signal processing (DSP)
is used upon selection of each model, thus optimizing both PIR and
MW performance within the protected area.
The PIR section of the NEXT DUO employs a cylindrical lens with
uniform detection sensitivity beginning at 0.5 m (1.8 ft) away from
the detector up to a distance of 12 meters (40 ft). Advanced True
Motion Recognition™ algorithm (patented) allows the NEXT
DUO to distinguish between the true motion of an intruder and
any other disturbances which cause false alarms.
A Test input permits switching the detector to the walk test mode
remotely without removing the front cover. An on-board motion
event jumper determines whether 1 or 2 consecutive motion
events would trigger an alarm. Figure 1. General View Figure 2. Inside View

This device complies with the essential requirements and
provisions of Directive 1999/5/EC of the European Parliament
and of the Council of 9 March 1999 on radio and telecom-
munications terminal equipment.
2.45 GHz has no restriction in any EU member state.
The term “IC” before the certification number IC: 1467A -
NEXTDUO (that is printed on the detector) signifies that the
Industry Canada technical specifications were met.
To comply with the Canadian standard RSS-210, this device
must be operated indoors only to provide maximum shielding
and to prevent interference to licensed services.

3.1 General Guidelines
A. Microwave radiation passes through glass and non-metallic
walls. Be sure, therefore, to select the correct model in
accordance with the room size. This is important to minimize the
effect of movements occurring beyond room limits which might
cause the MW section to trip.
B. Large reflecting objects (especially metals) in the coverage
area can distort the microwave detector's coverage pattern.
C. If two NEXT-DUO 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 20 cm (0.6 ft) apart.
Attention! At power up, the detector undergoes a 60-second
stabilization period, indicated by alternate flashing of the red
and green LEDs.
