Destination and use
The device of type SW868 is intended for use in the European Union. It
complies with the European Union’s Directive 2014/53/EU (RED) for
radio equipment.
The device of type SW915 is intended for use in Canada, USA, and Mex-
ico. It complies with the requirements of FCC Rules and IC Rules, RSS-
210. It has an approval number for the Mexican states.
The device of type SW917 is intended for use in Brazil. It complies with
the requirements of Resolução 242/2000.
The device of type SW922 is intended for use in Japan. It complies with
the requirements of ARIB STD-T108.
The radio repeater is used to extend the wireless range of radio trans-
mission. The transmission is carried out at a frequency of 868.3 MHz
(EU) or 915.0 MHz (USA, Canada, Mexico) or 917.0 MHz (Brazil) or
916.5 MHz (Japan).
The transmitters must conform to the steute Wireless protocol of the
LR and ULR modules. A radio repeater is only required if the building
facilities impede an undisturbed reception or the distance between
transmitter and receiver is too great. Only signals of radio wireless de-
vices are received, checked and transmitted with full power. The 1K re-
peater ignores signals from other repeaters in order to minimise the
data volume. The 2K repeater also processes signals from other re-
peaters. Radio repeaters do not have to be taught in. They receive and
amplify radio signals of all radio transmitters in their wireless range.
Mounting / Wiring
Use suitable antennas only: Antenna with cable and SMA plug-in con-
nector, Material no. 1188958 (SW868/922) or 1188987 (SW915/917).
Mount the antenna on a metal plate. The metal plate serves as HF
counterweight. Minimum size of metal plate: 250 x 250 mm. Note
minimum sideways distance to nearest wall or disturbance source:
>300 mm. Do not bend or clamp the cable. Minimum bending range
of cable: >15 mm.
Design of wireless range
Because radio signals are electromagnetic waves, the signal is attenu-
ated on its way from the transmitter to the receiver. This means the
electrical as well as the magnetic field strengths decrease inversely
proportionally to the squared distance of transmitter and receiver
(E,H~1/r²). In addition to this natural restriction of the wireless range,
further interference factors occur: Metal parts, e.g. armours in walls,
metal foils of thermal insulations or vapour-deposited metal layer
heat protection glass reflect electromagnetic waves. Therefore, a so-
called deadspot can be found behind them. Radio waves are able to
penetrate walls, but the attenuation increases even more than in the
free field.
Penetration of radio waves:
wood, gypsum, glas uncoated
90...100%
brick stone, press boards
65...95%
armoured concrete
10...90%
metal, aluminium lamination, water
0...10%
Typical wireless ranges:
Sight connection in free field (LR):
approx. 450 m
Sight connection in free field (ULR):
approx. 700 m
Sight connection in free field (SW922 LR):
approx. 150 m
Sight connection in free field (SW922 ULR):
approx. 230 m
Sight connection indoors (LR):
approx. 40 m
Sight connection indoors (ULR):
approx. 50 m
Sight connection indoors (SW922 LR):
approx. 20 m
Sight connection indoors (SW922 ULR):
approx. 25 m
To get the maximum range: use the specified antennas. With other an-
tennas, the maximum range may differ.
Notices
The electrical connection may only be carried out by authorised per-
sonnel. The wireless repeater must not be used in connection with
other devices whose direct or indirect purpose is to ensure life or
health, or whose operation may pose a threat to humans, animals or
material assets. Subject to technical modifications. The described
products were developed in order to assume safety functions as part of
an entire plant or machine. The responsibility taken by the manufac-
turer of a plant or machine implies to secure the correct general func-
tion. Moreover, steute does not assume any liability for recommenda-
tions made or implied by this description. From this description new
claims for guarantee, warranty or liability cannot be derived beyond
the general terms and conditions of delivery.
Setting-up operation
After providing the operating voltage to the repeater, the green LED is
on and indicates the operating state. As soon as a valid telegram is re-
ceived and passed on, the orange LED lights up shortly.
Maintenance
With careful mounting as described above, only minor maintenance is
necessary. We recommend a routine maintenance as follows:
1. Check function
2. Remove dirt
Cleaning
- In case of damp cleaning: use water or mild, non-scratching, non-
chafing cleaners.
- Do not use aggressive cleaners or solvents.
Clean enclosure on the outside only. Clean enclosure with household
cleaning agents. Do not use compressed air to clean.
Disposal
- Observe national, local and legal regulations concerning disposal.
- Recycle each material separately.
