Warning
: unlike HD35RE repeaters, which have external power supply, the HD35REW repeaters are powered only by the internal bat-
tery. To extend the battery life, the RF stage of the HD35REW repeaters is not continuously active; therefore, the HD35REW repeaters are
subject to the following restrictions:
o
the alarm events may be reported with a certain delay;
o
the reconfiguration of the system may take longer; furthermore, if the configuration of a data logger with LCD is changed via the
logger keyboard, the change is not notified to the base unit and to the HD35AP-S software;
o
to guarantee the same transmission reliability of a system with HD35RE repeaters, HD35ED… devices may be obliged to transmit
the same packets several times: this could affect battery life.
