VIP-851-25 & VIP-851-70/100
SIP 20W GATEWAY 25/70/100V
INTRODUCTION
The VIP-851-25 and VIP-851-70/100 SIP 20W
Gateways enable voice access to a single zone of
one-way paging over an IP network, allowing page
zones to be extended anywhere network
connectivity is available. The VIP-851 can be
programmed as a SIP (Session Initiation Protocol)
device for connectivity to virtually any VOIP (Voice
over IP) telephone system.
The VIP-851-25 has output connections for line
level and 25-volt speakers only. The VIP-85170/100 has output connections for line level and
25-volt, 70-volt or 100-volt speakers.

INSTALLATION
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.
Precautionary Designations
Mounting
The VIP-851 is designed for rack mounting or wall
mounting.
Rack: Secure mounting brackets to the VIP-851.
Place the VIP-851 into a standard 19” rack and
secure with proper hardware (not included).
Wall: Attach mounting brackets as shown in Figure
1, and secure to wall with proper hardware (not
included).
Figure 1. Mounting
Power Connections
The preferred method of powering a VIP-851 is via
a Power over Ethernet Plus (PoE+) switch meeting
the 802.3at specification.
If the rear panel barrel connector is used for power,
the preferred power supply is a Valcom VIP-1124D.
Make all required signal connections before
applying power to the unit. If powering via 802.3at,
make sure all signal connections via the back panel
are made then connect the VIP-851 to the Ethernet
switch.
If power is supplied via the barrel connector, make
sure all signal connections are secure. Attach the
unit to the network via the front panel RJ-45
Ethernet connector. Apply power by plugging the
power supply into the VIP-851 via the barrel
connector on the rear of the VIP-851.
Network Connection
The VIP-851 has one RJ-45 network connector on
the front panel. Use a standard Ethernet patch
cable to connect the VIP-851 to an Ethernet switch.
Signal Connections
The VIP-851 has signal connectors on the rear
panel:
AUX audio input
1 Contact Closure input
2 Audio outputs (VIP-851-25)
3 Audio outputs (VIP-851-70/100)
1 Form C relay
AUX Audio Input: Line-level audio may be input
via the rear panel screw terminal block labeled
AUX. Nominal input impedance is 600 Ohms.
Audio connected on AUX can be directed to the
locally-connected speakers (Outputs connections)
or across the network to other Valcom devices.
Audio input is typically used for Background Music,
and will be muted during a Page.
Contact Closure Input: Contact closure input
labeled CC is provided for connecting an external
contact (relay, switch, etc) to trigger actions in the
VIP-851. The contact closure can be programmed
to activate the AUX Audio Input to send audio
across the network, or to remotely activate a relay
on another Valcom device across the network.
