Planning Notes
d
Limiting values:
- Maximum 30 DOW 1171 wireless smoke detectors per FK 100 LSN RF
expansion module.
- All RF expansion modules and all RF smoke detectors are LSN elements
(1 FK 100 LSN + 30 DOW 1171 = 31 LSN elements).
- Maximum 127 LSN elements permissible per NVU.
d
If several RF expansion modules are installed in the same area, a minimum
distance of 2m must be retained between the individual FK 100 LSNs.
In addition, the maximum distance of 40m between FK 100 LSNs or
attenuation of 90dB must not be exceeded.
d
The RF expansion module must not be installed in a metal cabinet!
d
A seperate power supply is required to provide power to the radio module, the
microprocessor and the peripheral accessories.
d
Power is supplied to the LSN part in FK 100 LSN via the two wires of the LSN line.
d
The pair of wires for the separate power supply can be looped through to supply
downstream LSN elements.
d
A magnet is required to activate the reed switch in the RF expansion module for
initial set - up of the radio system without fire panel.
d
If a building has unusual wall structures, field strength measurements must be
taken using mobile test device DZW 1171 to ensure reliable planning.
d
The Radiospy software with field strength measuring device is a convenient tool for
planning and displaying a radio cell using a PC/laptop.
d
The integrated radio module has been approved in the following countries:
Austria, Belgium, Croatia, Denmark, Germany, Italy, Luxembourg, The
Netherlands, Norway, Portugal, Spain, The Czech Republic, Slovenia, Sweden,
Switzerland, The United Kingdom
