*NOTE:
These specifications are applicable for all system components used in the eXentro
Voice Alarm system. At low temperatures LCD displays may suffer from 'blacked-out' screens!
Make sure to have an average temperature of about 20 degrees C. in the technical room.
**NOTE:
Max power consumption is measured with the maximum number of 4x4 cards installed
and maximum number of emergency panels connected.
