BARRIER OPTICAL BEAM
LINEAR SMOKE DETECTOR
RK100B - RK200B
GENERAL
Note : the following instructions are suitable for the RK100B and
RK200B models.
The RK100/200B is a new conception of optical beam smoke
detector barrier. It’s composed by a Transmiter and a Receiver,
and bases its working concept on the interaction between the smoke
present in a room and an infrared beam emitted by the Transmitter
and directed to the Receiver placed on the opposite wall of the
room to be protected.
For a correct installation, we recommend to read and follow our
instructions carefully. The excellent working results of the device
will widely compensate the time spent reading these instructions.
1 - QUALIFIED PERSONNEL
1.1 - All the operations of installation, setup, startup, maintenance
and verifications of operation of the RK100/200B detector must
only be performed by qualified personnell. These people are
qualified for their experience, specialization courses, knowledge
of the current standards and of the technical specifications,
features and usage method of the product.. These people therefore
are able to avoid errors or damages and assure an optimal
functioning of the product.
2 - NORMATIVE REFERENCES
2.1 - For the installation in European Community countries you
must follow the EC standard EN54-14 (Fire detection and fire
alarm systems). In extraeuropean countries you must respect the
relevant internatiobnal and national standards.
3 - INSTALLATION
3.1 - For the installation of the RK100/200B we suggest to use,
besides the normal tools (drill, expansion plugs, etc), also the
following elements:
• 1 - 7mm “C” key
• 1 - alignment lamp (we recommend to use our LAL02 lamp or
an electric torch with a powerful and contrated beam)
• 1 - tester (we recommend an analogic hand Tester or our analogical
STS01 meter (optional) to be plugged on the special connector
positioned on detector’s circuit.
3.2 - Remove the TX and RX cover acting on the 4 fixing screws
set on the 4 angles of the cover (fig.2).
3.3 - Install the Transmitter at a distance from the ceiling within
the 10% of the height of the room to protect. This distance can be
varied by the system designer if particular environmental conditions
exist. Wall fixing must be done with care using the 4 holes provided
inside the container. If the wall is a solid masonry one, 4 expansion
plugs are enough. It’s extremely important that the fixing wall or
surface is rigid and not subject to deformations.
3.4 - install the Receiver on the opposite wall and at the same
height of the Transmitter. It is not necessary that the device is
perfectly in front of and perpendicular to the receiver (angle
mistake up to 5 degrees is possible in all directions).
We recommends, for the cables economy, to install the Receiver
in the nearest position to the alarm control unit.
3.5 - get the cables inside through the holes obtained breaking the
suitable zones marked on the sides of the detector’s base..
4 - CABLE CONNECTIONS
4.1 - the low detector’s power consumption (20 mA with normally
open alarm relay contact (NO) and 30 mA with normally closed
alarm relay contact (NC)) allows to use small size sections cables.
We suggest to use a shielded cable with 8 conductors + shield (
2x0,75 mmq for power conductors + 6x0,22 mmq for the signal
conductors) for a distance up to 1 Km. In such way it is possible to
get a remote connection of the following signals:
• alarm relay contact (terminals C1-N1)
• turbulence (heat) alarm relay contact (terminals C2-N2)
• fault relay contact (terminals C3-N3)
• analog signal output (terminal SIG) - for level signal measurement
from distance
The shield of the cable must be connected as in fig.14.
5 - ELECTRICAL CONNECTIONS AND INITIAL SETUP
5.1 - Connect the device cables as shown on the labels facing the
terminal board. The given symbols indicate what follows:
• (V+) - (V -) - supply’s terminals 11 - 30 Vdc.
• (C1) - (N1) - normally closed alarm relay contact. The connection
is valid when the detector is not in alarm state and JP2 jumper is in
2 - 3 position. If JP2 is positioned on 1-2 the contact results
normally open. C1-N1 terminals are voltage free.
• (C2) - (N2) - turbulence alarm normally closed contact relay.
Connection is valid when the detector is not in an alarm state and
JP3 jumper is in 2 - 3 position.. If JP3 is positioned on 1-2 the
contact results normally open. C2-N2 terminals are voltage free.
• (C3)-(N3) - normally closed fault relay contact. Connection is
valid when the detector is not in fault state and JP4 jumper is in 1
- 2 position. If JP4 is in 2-3 position the contact is normally open.
C3-N3 terminals are voltage free.
Fault relay is normally powered (intrinsic safety)
• (SIG) - 0-5V analog output terminal. To use only during allignment.
