Characteristics
• DMD3-1 is a combined detector for ceiling mounting.
• DMD3-1 can be used in two basic ways:
- Motion detector
- Sensor luminescence
• The unit is equipped with two communication interfaces:
- Installation iNELS BUS
- DALI
• The motion detector is used to detect people moving in the area. Using the passive scanning
infrared spectrum for detection.
• Integrated luminescence sensor can be used for sensing current luminescence at the point of
installation of the unit. This information can be used in tasks to maintain a constant luminescence.
In space where it is possible, thanks to the contribution of natural light from the outside to adjust
the artifi cial light, which can reduce energy consumption.
• Setting the communication interface is done using the SET button.
• The unit can be confi gured via the iNELS3 Designer & Manager software, which, among other
things it is possible to:
- Set the desired function depending on detected motion.
- Resolve jobs based on the value of luminescence.
- Enable / disable the alarm LED on the detector housing.
• DMD3-1 detector is designed for indoor installation and is not intended for outdoor use.
• DMD3-1 detector is powered directly via the iNELS BUS installation (nominal 27 V DC) or DALI BUS
(nominal 16 V DC).
General instrucions
CONNECTION TO THE SYSTEM, INSTALLATION BUS
iNELS3 peripheral units are connected to the system through the BUS installation. Installation
BUS conductors are connected to the terminal units to BUS + and BUS-terminals, wires cannot be
interchanged. For installation of BUS it is necessary to use a cable with a twisted pair of wires with
a diameter of at least 0.8 mm, the recommended cable is iNELS BUS Cable, whose features best
meet the requirements of the BUS installation. Bearing in mind that in terms of all the properties
iit is it is possible in most cases also use the cable JYSTY 1x2x0.8 or JYSTY 2x2x0.8, however it is not
recommended as the best option. In the case of a cable with two pairs of twisted wires it is not possible
to use the second pair of the other for modulated signal due to the speed of communications; it is
not possible within one cable to use one pair for one segment BUS and the second pair for the
second segment BUS. For installation of BUS it is vital to ensure that it is kept at a distance from the
power lines of at least 30 cm and must be installed in accordance with its mechanical properties.
To increase mechanical resistance of cables we recommend installation into a conduit of suitable
diameter. Topology installation of BUS is free except for a circle, each end of the BUS must terminate
at terminals BUS + and BUS-. While maintaining all the above requirements, the maximum length
of one segment of the installation BUS can reach up to 550 m. Due to the data communication
and supply of units in one pair of wires, it is necessary to keep in mind the diameter of wires with
regards to voltage loss on the lead and the maximum current drawn. The maximum length of the
BUS applies provided that they comply with the tolerance of the supply voltage.
For the management of DALI BUS there is not an exact cable type recommended, but it is important
to keep some installation conditions. For DALI BUS lines up to 100 m the recommended min.
conductor cross section is 0.5 mm
2
. For management between 100 m -150 m a cross section of 0.75
mm
2
and more than 150 m the recommended min is 1.5 mm
2
. Management of more than 300 m
is not recommended. The voltage drop at the end of the installation may not be greater than 2 V.
CAPACITY AND CENTRAL UNIT
It is possible to connect to the central unit CU3-01M or CU3-02M two independent BUSes by means
of terminals BUS1+, BUS1- and BUS2+, BUS2-. It is possible to connect to each BUS up to 32 units, so
it is possible to connect directly to the central unit a total of 64 units. It is necessary to comply with
the requirement of a maximum load of one BUS line - maximum up to 1000 mA current. It is the sum
of the rated currents of the units connected to the BUS line, other units can be connected using the
units MI3-02M, which generate further BUSes. These are connected to the CU3 unit via the system
BUS EBM and you can connect a total of 8 units via EBM BUS to the central unit MI3-02M .
SUPPLYING THE SYSTEM
For supplying power to system units, it is recommended to use the power source of ELKO EP titled
PS3-100/iNELS. We recommend backing up the system with backup batteries connected to the
source of PS3-100/iNELS (see sample diagram of connecting the control system).
GENERAL INFORMATION
To operate the unit, it is necessary that the unit is connected to a central unit CU3 series, connected
to the central unit of the system CU3, or to a system that already contains this unit as its expansion to
include further system. All unit parameters are set through the central unit CU3-01M in the software
iDM3.
There is LED diode on the PCB for indication of supply voltage and communication with the
central unit series CU3. In case that the RUN diode fl ashes at regular intervals, so there is standard
communication between the unit and BUS. If the RUN diode lights permanently, so the unit is
supplied from BUS, but there is no communication between BUS and unit. In case that RUN diode is
OFF, so there is no supply voltage on the terminals BUS+ and BUS-.
Light sensor
Connection
• For proper function of the detector it is necessary to eliminate all interference from heat or light
sources in the sensing area.
• The detector cannot be installed on an unstable or vibrating surface.
• Lower mounting height will reduce the overall size of the detection zone.
• The distance from the unit and the colour of the illuminated area aff ects the resulting value of the
measured illumination by the DMD3-1 unit.
Scanning range
Motion detector
Setting
• Long press of SET key (> 8s): BUS change (DALI/BUS)
• Short press of SET key (< 1s): Signalling of the selected BUS:
- DALI - LED RUN fl ashes 1x long fl ash
- BUS - LED RUN 3x fl ash
