FCC Information 

This equipment has been tested and found to 
comply with the limits for a Class A digital 
device, pursuant to Part 15 of the FCC Rules.  
These limits are designed to provide 
reasonable protection against harmful 
interference when the equipment is operated in 
a commercial environment.  This equipment 
generates, uses and can radiate radio 
frequency energy and if not installed and used 
in accordance with the instruction manual, may 
cause harmful interference to radio 
communications.  Operation of this equipment 
in a residential area may cause harmful 
interference in which case the user will be 
required to correct the interference at his own 
expense.  
 

INSTALLATION

 

Operation:  

Provides talkback intercom via Network connection 
to customer telephone system or stand alone 
telephone set.  Interface to customer telephone 
system can be via SIP registration, FXO port or 
FXS port (additional equipment required in all 
cases).  The call button may be programmed to 
initiate a call to one of the above telephone system 
interfaces. When the call is answered, a hands-free 
communications path is established to the horn. 

   

Mounting (Network Interface) 

The Network Interface is designed for wall or table 
mounting and must be within 100 meters of the 
network switch. 
 

Wall: 

Using the wood screws provided, secure the  

Network Interface to the wall. 
 

Mounting (Horn)

 

Flush Mount using Mounting Screws 

The cardboard packing material in which the horn is 
shipped also serves as the template for flush 
mounting.  Using the template, mark location of 
opening and mounting holes on wall.  Drill holes 
appropriate to mounting hardware and cut out the 
opening.  Make appropriate wiring connections and 
test the speaker for operation.  Using appropriate 
mounting screws (not furnished) drill and mount the 
flange as shown.

 

 
UNIVERSAL BRACKET

 

Loosen or separate the universal bracket leaves by 
loosening or removing the handle and hardware.  
Using the back leaf as a template, mark the wall 
through the mounting holes.  Drill and mount to the 
wall using appropriate screws (not furnished) or 
mount directly to a junction box.  Mount the 

T-bracket to the back of the horn as shown using 
the (2) ½ inch screws provided. 
 

"C" CLAMP FOR "I" BEAM MOUNTING

 

A "C" clamp is provided with the horns to allow 
mounting to a beam.  Place the bolt through the hole 
in the bottom of the base to secure the "C" clamp to 
the beam.  It is suggested that the horn be mounted 
to the underside of the "I" beam to provide maximum 
positioning adjustments.  Mount "C" clamp with (2) 
½ inch screws provided. 
 

Power Connections

 

The only method of powering the Network Interface 
is via a Power over Ethernet (PoE) switch or power 
injector meeting the 802.3af specification.  
Make all required signal connections before 
connecting to Ethernet switch or power injector 
meeting the 802.3af specification. 

 

Network Connection 

The Network Interface has one RJ-45 network 
connector and one RJ-45 horn connector.  Use 
standard Ethernet patch cable to connect the 
NETWORK connector of the Network Interface to a 
PoE Ethernet switch.  
 

Signal Connections 

Audio output connection is made from the Signal 
Output.  The RJ-45 connector on the horn is 
connected directly to the RJ-45 Signal Output 
socket on the IP Link.  See Figure 1. 
 
 If additional length is required, any standard 
T568B extension may be used. See Figure 2

 
If required, a normally open call button may be 
connected to the white blue pair (pins 4 and 5) of 
the HORN RJ-45 connector.  See Figure 2. 

 

Status Indicator Lights 

The VIP-490AL has 2 status indication lights on the 
front panel:  

 

Green LED:  

(Link) Indicates Ethernet connection 

when illuminated. 

 
Yellow LED: 

(Activity) Indicator flashes to indicate 

network activity.
