PSE" output of the intercom unit is used to power other devices, IEEE802.3at compatible PoE switch must be used to
power the intercom unit.
In the case both a PoE switch and Aiphone PS-2420 power supply are used in combination to power the intercom
unit,PS-2420 can provide back-up power if the PoE power supply fails. this allows continuous recording function etc.
to continue operating.
