2 Installation
This chapter shows you the steps necessary to install the IP Horn loudspeaker and the IP
Amplifier module.
2.1 LHN-UC15L-SIP or LHN-UC15W-SIP IP Horn loudspeaker
2.1.1 Considerations
Before installing the IP Horn loudspeaker, consider the following:
Mounting location:
The IP Horn loudspeaker must be fixed to a stable and suitable surface to support its weight.
– The mounting surface must be able to support more than the nominal weight of a single
loudspeaker.
– Choose the mounting location where there is an unobstructed line-of-sight path between
the horn and the intended area of coverage.
Required tools
– M13 wrench (fasten torque: 5-6Nm)
– T20 Torx screwdriver (fasten torque: 1.3-1.8Nm)
2.1.2 Mounting
The IP Horn loudspeaker comes with a metal bracket attached. The mounting bracket has one
central hole and two slotted holes adjacent to it. The central hole has a diameter of 6.8mm.
The slotted holes are 15mmx7mm.
Figure2.1: Mounting bracket
To mount the IP Horn loudspeaker unit to a wall or any other solid surface, do the following:
1. Using a M13 wrench, remove the side screws and washers that attach the bracket to the
IP Horn loudspeaker.
Remove the bracket from the IP Horn loudspeaker.
2. Fit the bracket in its final position and secure it with one screw in the central hole.
3. Rotate the bracket until you achieve the position you desire.
4. Affix the bracket with two screws in the remaining slotted holes.
5. Reattach the IP Horn loudspeaker to the bracket, inserting the side screws and washers.
6. Make sure the IP Horn loudspeaker is facing the ground in a 10° angle.
7. Fasten the side screws to lock the IP Horn loudspeaker to its final position with a torque
of 5-6Nm.

2.1.3 Connections
To access the cable connections, do the following:
1. Using a T20 Torx screwdriver, remove the four cover screws.
2. Lift the cover from the chassis with care.
The back of the IP Horn loudspeaker shows as the reference view bellow.

Figure2.2: Back panel of the IP Horn loudspeaker (without the cover)
Connecting the network (Figure 2.2, callout 1)
The IP Horn loudspeaker supports PoE/PoE+ power supply mode. You need one Ethernet
cable to connect to a PoE switch or injector for a convenient installation. For the most reliable
operation, always use shielded CAT-5e or higher class cables.
i
Notice!
Connect the IP Horn loudspeaker using shielded network cables that are properly grounded.
To connect the network cable:
1. Cut an Ethernet cable to the desired length.
2. Thread the Ethernet cable through the cable gland on the bottom left of the cover.
3. Crimp the RJ45 connector to the cable.
4. Connect that end of the cable to the network port (Figure 2.2, callout 1).
4Verify the network connection:
The network port LED turns on a few seconds after the network cable is connected,
indicating that PoE/PoE+ power has been successfully applied.
There are two lights on the Ethernet jack:
– A solid green LED (right) indicates the port is operating at 1000Mbps (1 Gbps). It flickers
to indicate network activity.
– An orange/yellow LED (left) indicates a network link of 100Mbps. It flickers to indicate
network activity.

2. Attach the cable gland (supplied) to the bottom right of the cover.
3. Thread the cable through the cable gland.
4. Connect the wires to the Audio terminal on the device (Figure 2.2, callout 3).
Reassembling the cover
After you make all the relevant connections to the IP Horn loudspeaker, reassemble the cover.
To reassemble the cover:
1. Fit the rubber seal on the cover. Make sure that the seal is properly placed.
2. Align the cover with the screw holes, with the cable glands facing downwards.
3. Using a T20 Torx screwdriver, tighten the four cover screws with a torque of 1.3 - 1.8Nm.

Figure2.4: Physical reset button and LED
Test/Reset button (Figure 2.4, callout 1)
There is a physical button for test and reset purposes. This button will perform different
actions depending on how long you press it:
1. Press and hold for 1 - 5 seconds: the IP Horn loudspeaker will play a default message to
test the loop between the speaker and the microphone. The IP Horn loudspeaker
performs a check that the speaker is operating and therefore the microphone is used.
When the microphone physical switch is On, the tone lasts around 2 seconds; when it is
turned Off, you hear a brief beep (approximately ½ second).
2. Press and hold for 6 - 10 seconds: the IP address of the IP Horn loudspeaker will reset to
factory default (DHCP);
3. Press and hold for 11 - 20 seconds: the IP Horn loudspeaker will reset to factory default.
Indication LED (Figure 2.4, callout 2)
The LED next to the Test/Reset button serves as a time indicator of how long the Test/reset
button is pressed. Once you click the Test/Reset button once, the LED lights up every five
seconds for as long as you keep the button pressed, and once more when you let go of the
button to indicate the reset is applied.
The LED next to the test button flashes slowly (1Hz) if the test is successful and quickly
(4Hz) when it is unsuccessful.

The chassis has 4 pierce-through holes that
you can drill for surface mounting. Each hole
has a maximum diameter of 5 mm.
The module comes with a DIN rail mounting
plate and 2 TX20 screws as part of the
components. To mount this into a DIN rail
(corresponds to TH 35-7.5 acc. to EN 60715)
you must first attach the mounting plate to
the IP Amplifier module.
Surface mount (A)
To mount the IP Amplifier module to a solid surface:
