Functions
Once you have connected
the unit to the mains power
supply, closed the housing
and fitted the lens, you are
ready to put the system into
operation. Two setting
controls are concealed
behind the front cover 쪨.
Important: Only carry out
time and light threshold
settings with the lens fitted.
Switch-off delay
(time setting)
The chosen light ON time
can be varied continuously
from approx. 10 sec. to a
maximum of 15 min.
Turning the adjustment
screw fully anti-clockwise
selects the shortest time of
approx. 10 sec., turning the
adjustment screw fully
clockwise the longest time
of approx. 15 min. The
shortest time setting is
recommended for setting
the detection zone and
performing the walk test.
Twilight setting
(response threshold)
The chosen detector
response threshold can be
adjusted continuously from
approx. 2 lux to 2000 lux.
Turning the adjustment
screw fully anti-clockwise
selects daylight operation
at approx.2000 lux. Turning
the adjustment screw fully
clockwise selects
twilight
operation at approx. 2 lux.
The adjustment screw must
be turned fully anti-clock-
wise for setting the de-
tection zone and perform-
ing the walk test in daylight.

The corner wall mount en-
closed with the unit pro-
vides a convenient means
of in-stalling the IS 2180-2
to internal and external
corners. Use the corner
wall holder as a template
for drilling the hole. This
way, you will drill the hole
at the right angle, allowing
you to fit the wall mount
with ease.
Installation using corner wall mount
b) Connect service lead
The service supply lead to
the light is also a 2 to 3-
core cable. Connect the
light’s current-carrying
conductor to the terminal
marked L’. The service
lead neutral conductor
must be connected to the
terminal marked Ntogether
with the mains lead neutral
conductor. Connect the
protective-earth conductor
to the earth contact ( ).
7. Screw on housing
and close again.
8. Fit lens (set reach to
either 5 m or 12 m max),
see ‘Reach setting’ section.
9. Select time 쪫and light
threshold setting 쪪(see
‘Functions’ section).
10. Locate front cover 쪨
and fit security screw 쪧to
protect cover from
unauthorised removal.
Important: Reversing the
connections may result in
damage to the unit.
The site of installation
should be at least 50 cm
from a light because heat
radiated from it may trigger
the sensor unintentionally
To obtain the specified
ranges of 5/12 m, the sen-
sor should be installed at a
height of approx. 2 m.
Installation procedure:
1. Detach front cover 쪨,
2. Release clip 쪬and flip
up lower half of housing,
3. Mark drill holes, 4. Drill
the holes, insert wall plugs
(6 mm dia.), 5. Break open
cable entry for surface or
concealed wiring.
6. Feed through mains
supply and service cable
and connect to terminals.
Use sealing plugs for
surface wiring.
a) Connect mains supply
lead
The mains supply leads is
a 2 to 3-core cable:
L= phase conductor
N= neutral conductor
PE = protective-earth
conductor
If you are in any doubt, you
must identify the cables
using a voltage tester; once
you have done so, discon-
nect the power supply
again. Connect the phase
(L) and neutral conductor
(N) to the clamp-type ter-
minal. Connect the protect-
ive earth conductor to the
earth terminal ( ).
A power ON/OFF switch
may of course be installed
in the power supply lead.
Alternatively, you may use
a normally closed contact
pushbutton to activate the
sensor manually for the
duration of the time setting.
Note: The internal-corner
wall mount may be used for
mounting the sensor to the
wall. The cables can be
conveniently routed down
the surface of the wall
behind the unit and fed
through the cable entry.
