PROXIMITY SWITCH
MULTIMAT
INSTRUCTIONS ON USE
DESCRIPTION
The MULTIMAT proximity switch detects invisible infrared radiation from
people and other heat sources without emitting any form of radiation.
When a heat source moves in front of the MULTIMAT, its output circuit is
activated and when it no longer detects the movement, it will deactivate
after an adjustable delay.
The MULTIMAT reacts in this way only when ambient light conditions are
below the selected level.
INSTALLATION
WARNING: The assembly and installation of the electric apparatus must
only be carried out by an authorised installer.
ALL POWER MUST BE SWITCHED OFF PRIOR TO COMMENCING
INSTALLATION WORK
The apparatus is fitted with an internal security circuit that protects it
against electromagnetic interference. However, certain especially strong
magnetic fields could affect its operation and therefore, it must not be
installed close to inductive loads (motors, transformers, telephony
antennas, transformer substations and industrial machinery etc).
MOUNTING
It can be mounted on walls or ceilings. For ceiling mounting, rotate the
head until the sensor is correctly orientated as shown in the following
diagram:
Highly reflective surfaces (liquids and marble etc) , elements subject to
sudden changes in temperature (heating and air-conditioning and possible
air currents) and also light sources must be avoided within its detection
area.
The base has 8 precut holes for flat wall installation. According to the
installation type (wall, inner or outer corner) you have to perforate the
most appropriate holes.
To install in an inner corner it is necessary to break the weak parts in the
installation base.
The ideal mounting height is between two and three metres and the
direction of movement of possible heat sources should be transversal to
the MULTIMAT lens.
It must be taken into account when installing the MULTIMAT that
detection takes place when the detection beams are crossed; therefore, if
the heat source to be detected is moving parallel to the beams, detection
will be produced at a smaller distance since it will not cross the beams
until it is very close to the apparatus.
In the above figures, the arrow indicates direction of movement of the
person or object to be detected.
The ambient temperature where the MULTIMAT is installed can
significantly affect detection sensitivity and hence, the detection distance.
Higher temperatures means reduced sensitivity because the apparatus
operates by detecting the movement of a heat source (in most cases, this
temperature is 36 ºC, that of the human body), the closer the ambient
temperature is to 36 ºC, the poorer the detection.
The securing base includes the electric connections so that it can be
installed in its position with the connections already made and then the
detector is fitted to the base. Similarly, if the detector has been
dismounted, there is no need to dismount the base.
