NEXT DUO
Dual-Technology, Digital MW/PIR Intrusion Detector
Installation Instructions
1. 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.

of 9 March 1999 on radio and telecommunications terminal equipment.
2.45 GHz has no restriction in any EU member state.
3. INSTALLATION
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 tempera- tures
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 equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
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 interference,
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.
