Introduction
Figure 01
The LRS 01 consists of a ventilation duct socket LKS 02 and an ORS 210
optical Smoke Switch with alarm latching. It is used for monitoring smoke
in ventilation ducts.
The LKS 02 provides a mounting for Smoke Switch ORS 210 and is fitted on the
outside of a ventilation duct. The LRS 01 is intended for use inside buildings.

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.

Figure 02 provides recommendations for project planning.
To ensure reliable
smoke detection, in large ducts several LRS 01 Smoke Switches should be instal-
led. The airflow parameters must be taken into account when determining
their positions.

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!
The carton in which the LRS 01 is packed complies with minimal package
requirements, and can support up to 10-times its own weight when stacked.
The package is only to a limited extent suitable for transport by post or rail. For
transport in tropical zones, transport by sea etc., special packages are available.
For further information, please contact the manufacturer.
Do not open the package until the Smoke Switch is to be installed. Keep the
installation instructions for future reference.

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.

Make sure that the direction in which the socket LKS 02 is installed corresponds
to the direction of airflow in the duct. To help with this, the LKS 02 has arrows
on its base showing the direction of flow (see Figure 05).
Figure 05
Warning!
When mounting the LKS 02 socket, it is important to ensure that the
airflow direction is correct, and that the socket is properly sealed.
