Dual-Technology, Digital MW/PIR Intrusion Detector

1111. 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)
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.

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 telecom­munications 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.

4. SPECIAL COMMENTS

Even the most sophisticated detectors can sometimes be defeated or may fail to
warn

due to: DC power failure / improper connection, malicious masking of the lens,
tampering with the optical system, decreased sensitivity in ambient temperatures
near that of the human body and unexpected failure of a component part.

The above list includes the most common reasons for failure to detect intrusion,
but 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, even though they are protected

by an alarm system.

This device has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in residential installations. This equipm ent generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the inst ructions, may cause
harmful interference to radio and television reception. However, there is no guarantee that
interference will not occur in a particular installation. If this device does cause such interf erence,
which can be verified by turning the device off and on, the user is encouraged to eliminate the
interference by one or more of the following measures:
– Re-orient or re-locate the receiving antenna.
– Increase the distance between the device and the receiver.
– Connect the device to an outlet on a circuit different from the one that supplies power to the receiver.
– Consult the dealer or an experienced radio/TV technician.

WARNING! Changes or modifications to this unit not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
