Use of transponders - SmartRelay 3 system
The transponder-to-reader range (read range) extends up to 100 cm.
Readers are able to communicate through materials such as wood, steel and concrete when used with active transponders. The reader can be mounted either on the inside or on the outer side.
NOTE
A transponder's read range may be reduced due to interference in the surrounding area.
Strong magnetic fields can shorten the read range. Aluminium structures may block communication between the transponder and reader.
You can enable the Close-up range mode option in the LSM software. This option reduces the B field reader range, reduces the impact from possible sources of interference and can prevent a transponder from overmodulating.
