IQ8Wireless transponder for wall mounting
28 FB 798941 / 10.06
The installation location of the IQ8Wireless transponder should be chosen so that the shortest
transmission path (wireless path) to the wireless bases can be implemented and that no
electro-magnetic interference is to be expected. The function of the IQ8Wireless transponder
may be seriously affected and its range reduced by interference sources or an unsuitable
installation location:
Electrical interference sources
• Energy/power cables
• Powerful wireless transmitters in the vicinity
• Switched-mode electronic circuits
• Computer and IT systems
Mechanical interference sources
• Metal grating and metal gates
• Metal cabinets (cabinet units)
• Concrete ceilings and concrete walls
• Unfavourable arrangements (angles) of IQ8Wireless transponders and IQ8Wireless
detector bases
The IQ8Wireless transponder operates with a range up to 25 channels within the
frequency band of 433 MHz and 868 MHz.
Also consider temporary interference sources such as mobile phones or
computers!
Requirements for the environment
• The quality of the wireless transmission depends very much on the ambient temperature.
A reduction in temperature in the monitored rooms, for example at night may have a
negative effect on the wireless quality achieved during the day.
• Sliding gates or doors which are open during the day for operational reasons as well as
overhead cranes may disrupt the wireless path when they are closed or in a different
position respectively.
To plan the wireless system the tools 8000 software contains a field strength
measurement tool. This can be used to check the quality of the wireless link
(field strength) between the IQ8Wireless transponder and the IQ8Wireless
devices.
If used properly, the “IQ8Wireless transponder (Part No. 805595)“ complies with
the basic directives and corresponding requirements in according to the
R&TTE Directive 1999/5/EC.
