SYSTEM DESCRIPTION
The ILIA mod.
MODEL ERRHS0712
detector consists of a
Transmitter/Receiver
Unit, with a Reflection Unit and a Beam Controller Unit
for programming, setting
and testing. The Beam Controller Unit is used to remotely manage the detector or
detectors in the field using a single line. The
Beam Controller Unit
is put at a place
on ground level from where the detector can be controlled without having to climb
up to the detector, as regards all normal operations. The Beam Controller Unit is
made of plastic, has a keyboard for programming and a backlight 16x2 display.
By entering a password of 4 digits you can program the system from ground level to
determine the detector's signal level, to check environmental disturbances, to set
the required thresholds based on these and to check the alarm threshold; the
default password
FFFF
can be changed by the programmer by following the
instructions in the remote programming menu.
The
system configuration menu
becomes available when you just touch any of
the 5 buttons on the keyboard and by then entering the default password
FFFF
on
the first programming session, customising the password from then on (the
password can be reset if lost or forgotten by use of the Beam Controller Unit's reset
hardware).
The Beam Controller Unit electronic base permits direct connection of two detector
units; by means of an
expansion circuit
(SMLS), it is able to pilot up to 8 detectors
connected together and a connection with two stub lines or by a closed loop.
With
this second typology the system continue proper working even if the cables are cut
or in the case of a short circuit by the protection circuit inserted in each single
detector. There are also programmable relay contacts in the unit for each individual
detector connected. These relays can have their polarity reversed with the use of
the software and permit the transmission to a single central unit of the individual
alarm, fault and maintenance request signals. Any breakdown in communication
between Beam Controller Unit and the detectors connected to it will be
immediately signalled by the simultaneous flashing of the yellow Led and the green
Led on the Transmitter and the Receiver, as well as being indicated on the display
of the Beam Controller Unit itself.
The
controller
is also available
in the Dust version
, suited to very difficult
environments, using special VdS certified software that enables the detection
threshold to be calculated up to the maximum limit permitted by standard EN54-12
without losing the principal characteristics of this model: producing early detection
in any environment.
ILIA with the Dust version controller has already come successfully through lab and
environmental real scale fire testing; these tests have shown that the model's
detection ability assures early alarm in any environment, overcoming unfavourable
conditions that could give rise to false or to fault alarms.
ILIA with the Dust version controller is thus a
highly reliable response to the needs
of problematic environments with dust, steam, fumes or particular working
processes where other technologies are unable to assure the required security
and accurate and precise detection.
