Planning of IQ8Wireless components
8.1
Planning information
When fire alarm systems are planned and installed e.g. in the Federal Republic of Germany,
they must comply with certain standards and guidelines, including the following:
DIN VDE 0100
•
DIN 14675
•
DIN VDE 0833
•
DIN EN 54
•
VdS Guidelines 2095, 2015, 2046, 2833 und 3448
•
Local building authority conditions
•
In principle, these requirements and specifications should also be complied with in the planning of fire alarm
systems outside the area of validity of these standards and guidelines.
Pay attention to the national and local requirements in accordance to the application area!
From DIN VDE 0833 – 2, section 6.2.5
On any one transmission route a maximum of 128 detectors or devices may be connected, not including
•
indirectly connected devices such as detector displays.
This means, per loop:
Max. 123 IQ8Wireless bases (incl. IQ8Quad fire detectors without integrated alarm device) divided between
•
4 IQ8Wireless transponders (= 127 addresses) / 117 IQ8Wireless bases (incl. IQ8Quad fire detectors without
integrated alarm device) divided between 10 IQ8Wireless transponders (= 127 addresses) and no further
detectors/transponders on the loop.
If extra detectors or transponders are operated on the loop, the corresponding number of wireless
•
components is reduced.
•
Each individual IQ8Wireless transponder must be powered via a separate protected supply line with an
external +12 V DC voltage.
If the power supply, e.g. from the FACP, is installed as fire area comprehensive, it must also be with E30
•
cable, alternatively the power supply can be via a DIN EN 54-4 defined and battery-buffered power unit in the
same fire area as the IQ8Wireless transponder.
Because an error (interruption, short circuit or error of a similar kind in a transmission route, e.g. defective
•
information transfer) may occur on the line of the power supply, the rule of one IQ8Wireless transponder for
fire detectors with IQ8Wireless base in a detection area applies.
•
The IQ8Wireless transponder must be installed at least in the same fire section as the detector area of its
assigned detector.
For further information refer to documentation of the IQ8Wireless devices.
