The BX-80N Guidebook
Early warning boundary protection
Product Concept
1. Product Concept
BX-80N is an advanced PIR
detector which is designed to
protect the immediate
perimeter of the building. It is
developed for the purpose of
“early warning” i.e. before an
intruder breaks into the
premises.
This product can only be used
for the boundary of a building.
(NOTE)
2. Do not use BX-80N when
intruder may pass by (i.e.
entrance of a building).
Use VX for such application.
1. Do not use BX-80N for
perimeter region of a property
like photobeams.

Unique and reliable detection area
The BX-80N creates a unique multi-layered, horizontal barrier and just
one BX-80N unit can protect a long area, because it is installed in the
center of the detection area and protects both sides.
It provides four detection areas (upper and lower areas for both sides)
and generates an alarm condition only when both upper and lower
detection areas are blocked simultaneously.
The BX-80N provides highly accurate detection even under severe
environmental conditions.

Product Concept
Enhancement of protection capabilities
When a general-purpose mechanical security system is installed,
detectors are usually located inside a building. In order to increase the
effectiveness of such a security system, Optex recommends not only
securing the inside of the building but also adding protection to the
outside areas.
By adding BX-80N, it detects intruders before entry. This invisible barrier
offers the first line of defense to a property’s boundary.

2. Features - to reduce false alarms in severe outdoor environmental conditions -
Both upper and lower detection areas
have to be activated to generate an
alarm condition.
This reduces false alarms,
particularly those caused by
temperature changes, light reflection
and small animals.
Size-judging function
The size judging function virtually eliminates false alarms due to small
animals.
Features
Two double-layered detection patterns
No detection
When only the lower zone
detects a moving object,
the unit is not activated.
When only the upper zone
detects a moving objects,
the unit is not activated.
When both the upper and
lower zones detect a
moving object, the unit is
activated.
No detection Detection

Adjustable detection length for appropriate detection area
The appropriate detection area has to be set for each installation site to prevent
false alarms.
The lower detection areas of the BX-80N is four-step variable. By setting the
appropriate detection area, the BX-80N drastically reduces false alarms as it
generates an alarm only when both upper and lower detection areas are
blocked simultaneously.
Features
12m (detection area)
8m (detection area)
5m (detection area)
2m (detection area)
ExampleDetection area pattern A
There are moving objects
(i.e. tree, bushes, etc.）
Detects the shorter range
[16m (8m single side)]
There are reflective
objects (i.e. puddle, pool,
metal plate, etc.)
No obstacle
in detection area
6
Detection area pattern C
Features
The angle of all detection areas can be adjusted horizontally by 0 to 3
degrees. If there are objects such as bay windows, troughs and so on
that are obstructing the detection area, please make concessions by
adjusting its angle to attain the appropriate area.
Both the lower detection areas of BX-80N operate individually. By setting
appropriate detection areas for each application, the BX-80N expands its
capabilities.
Detection area pattern B
The angle of all detection
areas are adjustable
horizontally 0 or 3 degrees.

Double Shielding
Double conductive shielding
Patented Double Conductive
Shielding Technology utilizes a
special conductive filter to cover the
element window, allowing infrared
energy to pass through, while
blocking and grounding out
unwanted light and RFI sources.
This helps reduce false alarms
caused by car headlights and more
particularly reflected sunlight.
The BX-80N uses advanced
temperature compensation to
automatically increase the
detector’s sensitivity under
high temperature conditions,
especially where the
background temperature
ranges from 35 –37 degree
C, close to that of the human
body.
Audible alarm – area check mode -
Built-in buzzer sounds an alarm while an alarm is occurring. This buzzer
can also be used to annunciate detection during area check mode.

1. Installation height
2. Install the BX-80N in the immediate perimeter(boundary)
of the building
Installation height is 0.8 – 1.2m.
BX-80N is designed to be wall-
mounted centrally on a building,
covering the building perimeter.
Be sure to install the BX-80N to
the immediate perimeter of the
building.
NOTE: Do not use BX-80N for
perimeter protection like
photobeams.
