Mounting tips and hints
• Reliable installation of wireless systems in a building
can be achieved by repositioning the transmitter and/
or receiver antennas outside any skip zone or by using
a repeater
• Ranges exceeding 30 m are possible given highly
favorable prerequisites: a larger free space as well
as optimum antenna designs and positioning
• The range penetrates furniture and persons within
the room
• Range penetrates through up to five plasterboard
drywalls, two brick or autoclaved aerated concrete
walls and vertically through one to two room ceilings
Important factors that reduce the radio range:
• Divider walls, false ceilings with metal panels
• Steel furnishings or metal-coated glass
• Switch mounted on a metal wall
• Use of metallic switch frames
• Fire walls, elevator shafts, stairwells
