Introduction
Safety Information
Cloud PM paging microphones operate from a low DC voltage, supplied by either an
AC adaptor or the Cloud host device to which the microphone is connected. As such,
the microphone requires few safety precautions.
However, note that both the metal base of the unit and the mic gooseneck will be
electrically connected to the chassis of the host device (e.g. Cloud zoner or mixer/
amplier) once the installation is carried out. This means that if the mains wiring of
the host device and/or the building is faulty, the microphone could present a shock
hazard. Fitting a suitable earth leakage circuit breaker (e.g. 30 mA RCD type) to the
mains supply of the host device can provide additional protection.
