2.3 Electric Installation

Electric Installation Step by Step

It is very easy to connect 2N® SIP Speaker Horn electrically. Follow the steps below to avoid equipment damage or electrical injury:

  • Connect the aditional microphone
  • Connect the UTP cable.
  • Connect a 24 V power supply (unless PoE is used).

Caution

  • Be sure to connect the 2N® SIP Speaker Horn power supply as the last step. The same applies to PoE supply from the LAN.
  • The device must be part of the electrical system of the building.

LAN Connection

2N® SIP Speaker Horn can be connected to a standard local area network using a LAN interface via the RJ-45 connector on the back panel. Always use CAT-5d or higher class cables for reliability reasons.

 

LAN Connection


The LAN interface is equipped with the Auto MDIX function for automatic straight or cross-over cable detection.

The LAN interface can also be used for the 2N® SIP Speaker, Wall Mounted power supply through active network elements or injectors meeting the IEEE 802.3af standard.

Note

  • With PoE, the integrated amplifier power output is limited to 8 W. To utilise the maximum power output of the amplifier, feed 2N® SIP Speaker Horn from a 24 V DC / 2 A external power supply.

Caution

  • We recommend the use of a LAN surge protection.
  • We recommend the use of a shielded SSTP Ethernet cable.

Power Supply Connection

2N® SIP Speaker Horn can be fed using active network elements or PoE injectors via the LAN interface. In case this option is unavailable, use a 24 V DC / 2 A (Part No. 914423E) power supply or another power supply on condition that you keep the nominal values included in the Mechanical and Electrical Parameters subsection.
Connect the 24 V DC power supply either to the back panel supply connector as shown on the figure below

 

Power Supply Connection

Warning

  • If you use an adapter other than the recommended one, do not exceed the nominal supply voltage value of 24 V. Also make sure that the supply voltage polarity is correct. Exceeding nominal values and/or incorrect connection may lead to irreversible damage of the equipment.
