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.

Mode of operation
The receiver module receive serial data from the corresponding transmitter, e.g. to transmit measurement values in digital form or for
the setup of alarm systems, etc.
The receiver module requires an DC voltage supply in the range of 7 to 14 V DC.
It is forbidden to modify or change component parts of the product !
The electronic components are not protected against weather conditions. Therefore, it should not be used in the exterior without taking
necessary precautions.
The cable connections should not be longer than 1 m.
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.

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.
Installation of this product has to be performed by authorised electricians only.
If you have not the corresponding expertise, ask qualified specialists or workshop for installation and commissioning. This
product and connected devices can be damaged as a result from inappropriate installation, connection or operation.
Furthermore, this could lead to other damages e.g. short circuit, fire or electric shock.
The product must not be installed or used in places where a risk of explosion may exist.
Do not touch antenna connectors with live parts.
The product should only be used in a case adequate for mains-voltage if applied!
Electrical devices should be out of reach of children. Please be extra careful if children are around.
The module is a state-of-the-art product. However, there is a risk of danger if installation or operation is performed by
unqualified personnel

System operating range
The system SH-7 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. Earth) 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.
