Infrared High Power Radiator
SZI1019
Introduction
The inlrared high power radiator SZI 1019 in
connection
with inlrared transmitters SI 1011,
SI 1012 or SI 1019 serves to cover large areas.
The incorporated
power supply 01 the inlrared
transmitter
is able to leed 0 n e SZI 1019 directly.
The number 01 connected
power radiators can be
increased without limit. The corresponding
power
supply has to be provided by additional power
supply units.
Description
The lrant panel carries 119 inlrared transmitting
diodes and one LED as lunction contra!. On the
rear side you will lind the 5-pin input connector.
To lacilitate connection
01 additional power radia-
tors, a 5-pin output connector is provided for
interconnection.
The input stage works as limiter amplilier, giving
the guarantee 01 an optimal amplitude lor the
output stages
-
independent 01the output level
01 the inlrared transmitter.
Eight parallel working
output stages are powering 15 diodes each.
Output stage no. 8 is equipped with one inlrared
diode with optical leedback, ensuring linearity of
the transmitted
signal.
Parallel working output stages guarantee high
security: If one diode is defective the corresponding
4
output stage switches off. The radiated power
decreases
by 1/8 with one output stage out of
order and by 1/4 with a second. II one more or
output stage no. 8 with optical leedback is out of
order, automatically
the complete SZI 1019 and
the red LED lunction control switches off.
The external supply voltage must be between
28 and 34 V.
One channel (mono) operation
II the SZI 1019 is powered by a mono transmitter,
additional power can be obtained. Therelore you
will lind a switch mounted on the p. c. board,
wh ich may be selected by a screw-driver
from
the rear side 01 the radiator through an indicated
hole. By means 01 this switch mono operation
gives increased power 01 25%.
Positioning the IR-System
When positioning the high power radiator please
keep in mind that the invisible inlrared light must
reach the lens 01 the receiver without shadowing.
A visible connection
between radiator and
receiver should be obtained to reach optimal
conditions.
High positioning with a slight tilt down-
wards has been lound advantageous in practice.
Flexibility is given by means 01 a 3/8" thread
adapter. For transportable
use we recommend

the table clamp MZT 237 or the floor stand
MZS 142, two power radiators can be adapted
using the twin-bar MZS 235. For stationary in-
stallations swivel mount GZG 1019 (wall and
ceiling positioning)
may be used.
The high power radiator is connected to the trans-
mitter by means 01 a Ilexible control cable.
This cable carries the RF-signal as
weil as the remote control signal to switch on the
connected
power supply units. For lixed installa-
tions this special cable (12 -1 036) can be ordered
per meter.
The lollowing
rule 01 thumb serves lor determina-
tion 01 the number 01 power radiators required:
Per channel and an area of 2 m2 one diode will be
required, that means wlth one high power radiator
and lour channels a coverage 01 approximately
60 m2 can be obtained.
