2.2.3. Distance between homologous devices
If different safety devices have to be installed in adjacent areas, the
emitter of one device must not interfere dangerously with the receiver
of the other device.
The TX
B
interfering device must be positioned outside a minimum
Ddo distance from the TX
A
– RX
A
emitter-receiver couple axis.
This minimum Ddo distance depends on:
•
the operating distance between emitter (TX
A
) and receiver (RX
A
)
• the effective aperture angle of the AOPD (EAA)
The following graphic shows the distance from the interfering devices
(D
do
) according to the operating distance (D
op
) of the couple ( TX
A
–
RX
A
).
