emissions of electromagnetic waves difficult or impossi-
ble. The source of interference sends out energy in the
form of electromagnetic waves, just like the instruments
affected by the interference, which overlap the original
waves either partially or completely.
Combination sounder
Combined sounder, e.g. siren (acoustic signal) + strobe
(visual signal).
Communication options
Used to transmit alarm notifications using additional
paths, e.g. wirelessly (wireless mobile module) for
voice/text messages or digital protocols.
