Safety warnings
쎱
Disconnect the power
before attempting any
work on the motion
detector.
쎱
The electrical connec-
tion lead must be dead
during installation.
Therefore, switch off the
power supply first and
check that the circuit is
disconnected using a
voltage tester.
쎱 Installation of the sensor
involves work on the
mains power supply.
This work must therefore
be carried out profes-
sionally in accordance
with the applicable
wiring regulations and
supply conditions.
쎱
Please note that the
sensor must be protect-
ed by a 10 A circuit
breaker. The mains
supply lead must be no
greater than 10 mm in
diameter.
쎱
Only carry out time and
light threshold settings
with the lens fitted.
Principle
The IS 2180 -2 is equipped
with two 120° pyro sensors
which detect the invisible
heat emitted by moving
objects (people, animals
etc.). The heat detected is
electronically converted
into a signal that switches
on loads (e.g. a light) con-
nected to it. Heat is not
detected through obstacles,
such as walls or panes of
glass. Heat radiation of this
type will, therefore, not
trigger the sensor. With a
90° angle of aperture, the
two pyro sensors cover a
detection angle of 180°. The
lens can be removed and
turned, thereby permitting
two max. basic reach
settings of 5 m or 12 m.
Using the wall mounts
provided with the unit, the
infrared sensor can easily
be fitted to internal and
external corners.
Important: The most
reliable way of detecting
motion is to install the unit
so that the sensor is aimed
across the direction in
which a person would walk
and by ensuring that no
obstacles (such as trees,
walls etc.) obstruct the line
of sensor vision.
