Presence detector PLUS, 41-802
Operation
The presence detector PLUS 41-802 integrates advanced PIR
and Ultrasonic technologies in one unit. The combination of these
technologies helps to eliminate false triggering problems even
in difficult applications. It is suitable for indoor application which
is ideal for using in open plan office, multi-stall public restroom,
conference room, under-ground parking lots, classroom, library, etc.
Function
By using the presence detector PLUS 41-802 it is possible to enlarge
the detection range. It is possible to connect up to 10 pcs. 41-802 to
one 41-800, which will control the load according to it’s settings.
41-802 has the same detection range as 41-800
To get complete coverage, when using more sensors, it is
recommended to calculate with approx. 20% overlap in the in
ultrasonic detection range. See
Fig. 3
.
Installation
Position:
The detector responds to movement and heat in relation to its
surroundings.
Avoid positioning the detector close to heat sources such as
cookers, electric radiators, ventilation systems or any moving
objects, cause by air flow, etc.
Also surfaces that are highly reflective, like large window or glass
sections can cause unwanted activation

.
It’s recommended that the detector is mounted on the ceiling. If
the detector is mounted suspended from the ceiling the ultrasonic
range is decreased.
Location:
The recommended installation height of this detector is 2 - 3m,
and 2.5m is the optimal mounting height. The detection range of
PIR sensor can reach up to ø8m, and ultrasonic sensor is an oval
shape of 8m x 10m with small movement (i.e. hand wave), and an
oval shape of 10m x 16m with large movement (i.e. walk).
The detection angle is 360° for both PIR and ultrasonic sensors.
See
Fig. 2
.
Installation:
Flush mount with a standard junction box or surface mounted by
using the surface mounting base.
When using the surface mounting base, there are 7 pairs of fixing
holes with various distances from 41mm to 85mm.
NOTE:
The direction of the ultrasonic sensor should aim to the main
detection area to achieve the best detection coverage.
Connection:
See connection diagram
Fig. 4
.
After connecting the detector to power, it takes approx. 30sec for
the detector to warm up. During this time the load will be switch ON.
Hereafter the detector will run according to it’s settings.
Limiting the detection range of PIR sensor:
If the detection range
is too large, it can be reduced by fitting the
enclosed lens mask.
It makes it poosible to reduce the maximum detection range of
Ø8 m to Ø6 m or Ø2 m and the angle of 360° can be reduced in
steps of 30°.

Setting the detection range. This has 4 preset settings:
“-“, min setting, which is approximately 2 x 3 m, 4 x 6 m, 7 x 8 m
and “+”, max. setting, which is approximately 10 x 16 m.

Trigger method:
Setting the triggering method. This has 4 preset settings:
PIR/US, PIR, US and PIR+US. This setting is use to select the
desired detection method.
Terminology
Trigger method:
PIR+US (PIR and US):
Where a defined detection or detection of minor motion is
necessary, choose this triggering method. It can also reduce
false triggering problem. For example, a classroom, an open-plan
office, etc.
Load will turn on when both PIR and Ultrasonic sensors detects
movement.
When load is On either PIR or Ultrasonic detecing movement will
keep the load On.
US only or PIR/US (PIR or US):
When there is high level of minor motion or obstacle (furniture
or partitions) existing in the monitored space, or it is a multi-stall
space. For example, a multi-stall public restroom, an office with
partitions, etc.
In PIR/US mode load will be turned on when either PIR or
