Installation and start-up
Installation of the Gira radio emergency set must be carried out by a skilled electrician.
He must observe the applicable requirements of DIN VDE 0834, DIN VDE 0100 and further
standards as well as statutory standards.
The devices of a radio emergency set are pre-configured for immediate use and are installed
in flush-mounted boxes.
2.1
Radio signals of the devices
Upon device installation several important rules must be observed to achieve the best
possible radio transmission:
-
The alignment or length of antennas must not be modified.
-
The distance between the radio call module and the other devices of an emergency set
should be at least 1 m (except the power supply unit).
-
If possible, maintain a distance to large metallic surfaces (e.g. metal doors) and large
electrical devices (motors, electrical switching cabinets etc.).
-
Also maintain a distance to other functional assemblies that also use radio
components.
-
Do not install near to the ground (at least 0.5 m above the ground).
Basic rule: the higher a radio component is installed, the longer its range.
-
Attenuation of radio signals is achieved by reinforced concrete, metal grids, thick walls
etc.
-
Damp in materials or in the room reduces the penetration of radio waves.
2.2
Recommended installation heights for the devices
DIN 18024-2 ("Barrier-Free Construction") specifies that operating elements are
mounted so they can also be easily reached by wheelchair users. A mounting
height of 0.85 m is specified.
With pull-cord buttons in bathroom units, specific requirements in DIN 0100-710
must be adhered to. Pull-cord buttons must be fitted at least 20 cm above the
highest possible position of the shower head.
It must be possible for the cord of the pull cord button to be reached by persons lying
on the floor.
i
Note: Reef knot on the handle of the pull-cord button.
The handle of the pull cord button must be attached to the pull-cord by a reef knot to ensure
that the cord cannot be pulled out of the handle.
2.3
Recommended installation height for the radio call module
The radio call module is for signalling an emergency situation and should be installed at
a height of 1.5 m to 2.2 m.
