1. Project planning
The socket LKS 02 is designed for use on rectangular ventilation ducts with
dimension “a” from 0.15 m to 1.0 m. It can also be used on circular ducts from
0.2 m to 1.0 m in diameter. The lateral reach of the inlet tube into a duct is ca.
500 mm. The ventilation duct socket must be placed so that reliable smoke detec-
tion can be assumed. Disruptive factors, which could affect reliable operation of
the LRS 01 must be eliminated.

3 General information
3.1 Operation of the LRS 01
When it is in operation, the Smoke Switch ORS 210 (in conjunction with socket
LKS 02) is continuously exposed to the flow of air in the ventilation duct being
monitored. When it detects smoke particles, an alarm is triggered and held. The
safety equipment is activated. Resetting is carried out by briefly interrupting the
power supply when the duct is free of smoke.
3.2 Transport, storage and unpacking
The LRS 01 is supplied in a suitable carton package. This package can be recy-
cled.
Please note the properties of the package!

4 Rules and regulations
The requirements of § 3 and § 17 of the MBO (Musterbauordnung = Specimen
Construction Code) apply to fire protection in ventilation equipment. These
paragraphs are incorporated into the local regulations issued by the States of
the German Federal Republic. Rules and regulations of the country in which the
equipment is installed must be observed.
Extract:
„Buildings and their equipment must be constructed so that measures are
incorporated to prevent outbreaks of fire and restrict the spread of fire and
smoke, and so that, in the event of a fire, the rescue of people and animals and
effective fire-extinguishing operations are possible.“
As a matter of principle, if a product simultaneously falls within the scope of
other directives, all directives will be applied in parallel so that the special
requirements of all directives can be fulfilled.

5 Installation instructions
5.1 Mounting the LKS 02
If the inside diameter of the ventilation duct is less than 350 mm, the inlet
tube must be shortened to suit. The inlet tube can be sawn off to the required
length.
To ensure reliable smoke detection, at least five of the holes in the tube
must be inside the ventilation duct (see Figure 04).
Figure 04
The tube must not be bent and it must be cut cleanly at right-angles.
When choosing a place to mount the LKS 02, take care that there is enough
space to change the inlet tube. If the inlet tube has not been shortened, a space
of at least 470 mm is required outside the duct.
The LKS 02 must be mounted on the duct using suitable fasteners, aligned with
the direction of flow, and sealed with rubber gaskets.
Ensure that the place where the socket LKS 02 is installed is, as far as possible,
free of vibration.

If the self-drilling screws (4.8 x 22) supplied are not suitable for fastening the
socket to the ventilation duct, use other more suitable fasteners. There are two
holes 6 mm diameter spaced at 206 mm in the base of the LKS 02 for mounting
it.
Two larger holes for the inlet and outlet tubes must also be drilled in the venti-
lation duct (see Figure 06).
Figure 06
Opening the LKS 02 cover
For servicing, the LKS 02 has quick-action clips. By pressing gently on the hous-
ing cover, it is easier to open or close the clips. If the LKS 02 socket is mounted
inverted, take care, when opening the transparent cover, that parts do not fall
on the floor (cover, suction tube etc.).
Handling
The connection lead for the Smoke Switch ORS 210 must be passed through the
plug supplied into the housing and connected.
The Smoke Switch ORS 210 is screwed into the socket LKS 02.
Then the inlet tube with flow adapter is fitted.
After a positive functional check with test gas, the cover of the LKS 02 can be
fitted by pressing gently on it and closing the clips.
Display of Smoke Switch ORS 210
The display of Smoke Switch ORS 210 is visible through the transparent cover of
the LKS 02 housing.
Application limits
This Smoke Switch should not be used where quantities of dust, smoke,
moisture or steam are to be expected from plant operations. Make sure that the
Smoke Switch will not be subject to dew formation. TheLRS 01 must not be used
out of doors. These instructions must be taken into account when planning the
installation.

5.2 Electrical connection of the ORS 210
At the cable gland and fastening, there must be no leakage to the ventilation
duct. When connecting or changing the socket, ensure that it is correctly ori-
entated to the direction of flow. In the LKS 02, the LED of the ORS 210 and the
arrow in the socket point towards the outlet tube. The LRS 01 can only operate
correctly when the cover is properly closed.
For cable entry, 4 x M16 plugs are fitted. When properly used, they comply with
the requirements of IP 54 within their 6 – 10 mm sealing range.
The sealing plugs can be replaced/supplemented by 16 x 1.5 cable glands with
M16 x 1.5 locknuts.

Mains connection
The power supply must be switched off before carrying out any work on the
mains unit!
The power supplies recommended for the Smoke Switch are NG 519 and NAG
03.
The installation can be operated by hand using the manual triggering unit DKT
02. At the same time, there is a permanent display of the operating status of the
installation.
Replacement/fault correction
Before fitting the Smoke Switch, before replacing a warning device, and before
trying to correct a fault (broken wire and/or short circuit), the mains power
supply must be switched off.
Cable installation
For low voltages, all normal, commercially-available telecommunications cable,
with or without screening, can be used. The conductor cross-sections must be
chosen to suit the current required by connected equipment and the installed
lengths:
Conductor diameter: min. 0.6 mm to max. 1.4 mm
Cable diameter: max. 9 mm
Recommended cable type: IY(ST)Y 4 x 2 x 0.6 mm
Only conductors with the same diameter may be connected at a terminal.
Cables must be installed so that they have adequate strain relief.
Contact loading
The electrical limits for loads on the relay contacts (30 V DC/1 A) must not be
exceeded - not even for short periods. Appropriate measures must be adopted
to protect the contacts.
Warning!
Safety-relevant switching-off and control of the installation must be carried
out using the relay contacts of Smoke Switch ORS 210. Status information,
transmitted via the communication interface (terminal 3), is purely for ease
of operation and information

6 Commissioning
Before commissioning the Smoke Switch in a ventilation system, the air ducts
and the LKS 02 must be cleaned carefully. Only then should the Smoke Switch
be removed from its packing and fitted to the LKS 02 socket.
6.1 Functional testing
Testing must comprise at least the following points:
The interaction of all items of equipment and their technical condition must be
checked. A check must be carried out to ensure that the detection parameter
(smoke) to which the optical Smoke Switch should react, can reach it. For func-
tional testing of the Smoke Switch ORS 210, test aerosol 918/5 must be used.
Test aerosol 918/5 is free of halogenated hydrocarbons (CFCs etc.). If a Smoke
Switch does not react when so tested, then it must be replaced. The inlet tube
must be free of any obstructions.
Warning!
The warnings and safety instructions on the aerosol can must be observed
without fail.
These tests and maintenance must only be carried out by a specialist or a person
trained to do so. The tests and their results are to be recorded in a logbook.

7 Maintenance instructions
Hekatron Smoke Switches are to be maintained in accordance with VDE 0833
Part 1 taking into account special ambient operating conditions. We recom-
mend that Smoke Switches are serviced in our works when they have been in
operation for 8 years. Under special ambient operating conditions (e.g. excessive
exposure, external influences, contamination etc.), servicing in our works may
be needed after a shorter period
By observing basic maintenance measures according to DIN 31051 in conjunction
with DIN EN 13306, the LRS 01 system should be kept permanently ready for
operation; it should be serviced annually as specified by the manufacturer.
Test aerosol 918/5 from HEKATRON is to be used for functional testing of Smoke
Switch ORS 210.
The interaction of all items of equipment and their technical condition must be
checked.
The inlet tube must be inspected visually at regular intervals. Any deposits
found must be removed. For visual inspection, the inlet tube must be removed
from the LKS 02 socket. After visual inspection and cleaning, the inlet tube must
be correctly replaced.
The Smoke Switch must not be opened!
