3.1.3 Examples of application
3.1.3.1 Ultrasonic sensor is less affected by humidity
which is more suitable for using in the moisty
environment (See FIG.5-A).

The cabinet.
The stalls of
3.1.3.2 Ultrasonic sensor detects occupant based on
the Doppler Effect and it does not need to
“see” directly the movement of occupant. In
other words, it is able to detect the movement
happened behind the obstacles (See FIG.5-B
& FIG.5-C & FIG.5-D).
FIG.5-E
FIG.5-F
FIG.5-G
3.1.3.3 Ultrasonic sensor is high sensitive in detecting
small movement, such as a minor motion of
typing, hand waving, door opening, etc. (See
FIG.5-E & FIG.5-F & FIG.5-G):
Light keeps off when
no movement is
detected.
Typing, light keeps
on.
Open the door,
light turns on.
3.1.4 Helpful tips for installation
Since the detector is in response to temperature,
airflow and wind change, please avoid the following
conditions:
Avoid aiming the detector toward the objects which
may be swayed in the wind, such as curtain, tall
plants, miniature garden, etc. (See FIG.6-A).
Avoid aiming the detector toward the objects
whose surfaces are highly reflective, such as
mirror, monitor, etc. (See FIG.6-A).
It is better to locate the detector at least 2m away
from the glass gate or window for avoiding
nuisance triggering because the shaking of glass
could trigger the ultrasonic sensor (See FIG.6-D).
FIG.5-H
FIG.5-I
FIG.5-J
3.1.3.4 Since ultrasonic sensor is high sensitive to the
small motion and does not require a direct
view between the sensor and the movement,
therefore, it is optimum for using in the spaces
where frequently has less or small motion
taken place, such as a conference room, an
open plan office with partitions, a library, etc.
(See FIG.5-H & FIG.5-I & FIG.5-J).

It is better to locate the detector at least 2m away
from the source of airflow such as doorway, vents
and air conditioning, etc. (See FIG.6-B & FIG.6-C &
FIG.6-E). If airflow causes the detector false
triggering, set ACC knob to ON position. After that,
if the false triggering still exists, lower the ultrasonic
sensitivity or select a more suitable location.
The distance between two detectors must be at
least 2m to avoid interference (See FIG.6-F).
The direction of the ultrasonic sensor should aim to
the main detection area to obtain the best coverage
(See FIG.3).

PRODUCT DESCRIPTION
2.1 Features
The Dual-Technology presence detector PMUSC
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 home, open-
plan office, multi-stall public restroom, conference
room, under-ground parking lots, classroom, library,
etc.
4
Non-
dropping
screw
Φ
3 x 18mm
US only or PIR/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.
PIR+US:
If the precise detection is necessary, choose this
triggering method which can reduce the false
triggering problem. For example, a classroom, an
open-plan office, etc.
Triggering mode application examples:
With its knobs and IR remote controller, the time,
ultrasonic sensor sensitivity, Lux, ACC (air current
compensation) function and PIR/US triggering
method can be adjusted as user desired to match
different application requirements and energy saving
for switching light on and off.
2.2 Additional functions
2.2.1 Function of terminal R
Connect terminal R with push button (N.O. type) to
manually control the load’s on / off. When the load is
off, press (>1sec) the push button (N.O. type) to
manually switch the load on. The load keeps on if the
movement is detected constantly. The load can be
automatically switched off if no movement is detected
and the delay time has expired, or by pressing the
push button again. When the load is off, the move-
ment cannot trigger the load on, and the detector will
return to the previous mode until detecting the last
movement and the delay time has expired. Refer to
FIG.7 for wiring connection.
PIR only:
If the monitored space is free of obstacle or has
high level of airflow or the detection area is needed
to be well specified. For example, a small-scale
office with air-conditioning, a small conference
room, etc.

2.2.2.1 Compatible with slave detector to achieve
this function. PMUSC can connect up to
10pcs slave detector which has the same
detection range as PMUSC to enlarge the
detection range. Under this mode, load and
LED perform according to the setting of the
master detector (PMUSC). Slave detector
works as a movement register to send signal
to master detector.
2.3 Dimension:
PMUSC :
Φ
111.5 x 67mm (See FIG.2-A)
2.2.3 Advance switching off function
To enhance energy savings, the detector is able to
turn off the controlled load prior to the set delay off
time if it detected the passing through occupant.
When the load is off, once the detector is triggered,
the load will keep on. If no movement is detected
again during 30sec to 3min, the load will on for
2.5min, and then off, even the time setting value is
more than 3min.

FIG.4-A
Dual-technology detector is capable of detecting
occupant without directly seeing the moving person
due to the high sensitivity of ultrasonic sensor.
Ceiling mount will give an overall view of the entire
room, and the detector should be mounted in the
center of the room so that the detector can detect
movement from anywhere of the monitored space.
If you choose the PIR technology (PIR+US or PIR
only) as triggering method, the detector should be
located where the PIR sensor is able to see the
occupant.
In order to ensure good reliability of PIR sensor, an
overlapping area is need to be considered while
installing several sensors in a space.
3.1.2 Location of dual-technology detector (See
FIG.4-A & FIG.4-B).
CAUTION!
Switches complying with this standard are
suitable for use at ambient temperature not
normally exceeding 25°C, but occasionally
reaching 35°C.
A circuit breaker (250VAC, 10A) type C according
to EN60898-1 shall be installed in the fixed wiring
for protection.
Do not mount on conductive surface.
Do not open the enclosure frequently.
Turn off power when change the light sources.
Bulb burn of certain brands would cause high in-
rush current which might damage the unit
permanently.
Installation and assembly of electrical
equipment must be carried out by skilled
person. Contact a qualified electrician
in the event of fault down.
