*1 Contact Input Specifications
*2 Audio Output Specifications
*3 Relay Output Specifications
*4 The intercom unit can be powered by using a PoE switch or Aiphone PS-2420 power supply. In the case "PoE
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.
