Signal light Operating Instructions ( D – GB – F )
Please read carefully!
These operating instructions form an integral part of this product and contain important information on how to commission, install and
operate it. They must be taken into consideration and given to the end user or other third party when the installer hands over the
product. These operating instructions must be retained for future reference.
Damage resulting from abuse or misuse is not covered by warranty. The manufacturer accepts no warranty for consequential losses
that may result directly or indirectly from use of this equipment. Any changes or modifications not expressly approved by the party
responsible for compliance could void the user´s authority to operate the equipment.
The product meets the requirements of the current European and national guidelines for electromagnetic compatibility. Conformity has been
established and the relevant statements and documents have been deposited at the manufacturer.
1 Mode of Operation
The signal light SHR-12 SL interprets the radio signals of transmitters and converts them into red and green light signals. Optional
potential-free relay contacts are also available to switch electrical devices. SHR-12 SL is suitable for all transmitters of the SH-12 series
and can be operated with up to 60 transmitters.
The signal light SHR-12 SL can be used in traffic light mode as a simple indoor traffic light or with the additional function as a ventilation
aid.
It should be noted that for applications that could put human life at risk, by using radio connection there is always
present a potential hazard due to extraneous disturbances. The Operating Instructions need to be followed at all
times.
2 Safety Precautions
Ensure that the product is isolated from any power supply before opening. Opening and installation of the product
must be performed only by a qualified electrician.
Further safety precautions

Every applicable regulations and standards have to be observed, in particular VDE0100, VDE0550/0551, VDE0700, VDE0711 and
VDE0860. The use of solid cables for connection is recommended since terminal design does not incorporate stress relief. The
product corresponds to Safety-Class II (without protective earth terminal) according to VDE0700, IEC335EN60335.

For commercial use, compliance must be made with the recommendations and instructions of the responsible regional/national
authorities.

For use in public institutions, schools, clubs and do-it-yourself workshops the operation of this product has to be supervised by
qualified personnel.

We do not assume any warranty and liability for personal or material damages caused by incorrect application or by failure to follow
these operating instructions.

For reasons of safety and conformity (CE) it is not permitted to modify or change parts of the product.

The product is a state-of-the-art product. However, there is a risk of danger if installation or operation is performed by unqualified
personnel
3 Range of operation
The system SH-12 is designed for a large operating range of many hundred meters. Walls including steel reinforced concrete can be
penetrated. The maximum range can be achieved under optimum conditions and by line-of-sight contact between transmitter and
receiver without disruption by external high frequency disturbances.
The following are possible causes that could reduce range of operation:

Obstructing buildings, vegetation or other factors will substantially reduce the operating range.

The distance between the antenna and the operator’s body or other conducting objects (e.g. Ground) may influence the working
range.

Background “electrical noise” could be relatively high so that the signal-to-noise-ratio may decease and therewith the operating
range. Also other devices, with similar operating frequency, operated in the neighbourhood of the receiver may reduce the
sensitivity.

Operating the receiver adjacent to badly shielded electronic components (e.g. PC’s) that can produce electromagnetic distortion,
may severely reduce the range of operation and could result in intermittent operation.

Adjustable and open components should not be adjusted or modified.
