•
Unplug the power supply before making any
connections to the control unit.
•
Do not locate the control unit closer than 18
inches or further than five feet from power
supply.
•
Do not use a lamp tester to check signals;
use a voltmeter. A lamp tester when first
applied is a short circuit to electronic circuits.
•
Do not apply power to the control unit until all
connections have been double checked.
Mounting
Mount the unit in a vacant space in an equipment
cabinet, rack or key system cabinet, allowing
enough room at the rear of the unit to plug in an
amphenol connector. Mount a 66B type
punchdown block near the unit and label it per
Figure 1.
Cabling
A 25 pair cable with a female connector should be
ran from the unit to the connection block. The
cable should be terminated on the connection
block in standard color code order. Verify that the
connections are correct prior to plugging the other
end of the cable into the V-1109RTVA Page Unit.
Connections to PABX System
The V-1109RTVA may be accessed by
connecting the W/BL and BL/W to the Tip and
Ring respectively of a Loop Start Trunk Circuit.
Refer to Figure 2 for connections
.
Connections to Electronic Key
Systems
The V-1109RTVA may be accessed by a C.O.
line position of an Electronic Key System by
connecting the W/BL, BL/W of the V-1109RTVA
to a spare line position of the Electronic Key. This
line position must be equipped with a trunk card.
Refer to Figure 2 for connections.
Connections to 1A2 Key System
The V-1109RTVA may be connected to a spare
button of a 1A2 Key Telephone by making the
following connections:
(A 400 type line card is
not needed in this application).
•
W/BL, BL/W of V-1109RTVA to spare button
Tip and Ring
•
O/W to Lamp Lead of spare button for lamp
connections
•
W/GR to Lamp Ground lead of spare button
NOTE: When the V-1109RTVA is connected to
a 1A2 Key System, connect W/O to Lamp
Battery or Ground. See Figure 3.
NOTE: For "Meet Me Page" on 1A2, connect
A-Leads from spare button using 10K Ohm
resistors in series with each A-Lead. The
other side of resistors are connected to the
BK/G (inhibit) of V-1109RTHF. Refer to Figure
3 for connections.
Power Connections
•
The V-1109RTVA is designed to use -24VDC
battery.
•
Connect the V/BR lead to Talk Ground.
•
Connect the BR/V lead to Talk Battery
(-24VDC filtered).
•
Connect the V/S lead to Signal Ground.
•
Connect the S/V lead to Signal Battery
(-24VDC unfiltered).
Speaker Connections
The outputs for paging zones start at the BK/BR
pair (zone 1) through the V/O pair (zone 9). Refer
to Figure 3 for typical speaker connections using
Valcom one-way amplified speaker assemblies
.
Page and Music Level Set-up
The V-1109RTVA has volume controls for the
following functions:
•
Master Page Control - located on back of unit
below amphenol connector
•
All Call Master Control - located on front of
unit
•
Background music input control Zones 1-5
•
Background music input control Zones 6-9
Control Set-Up:
1. Master Page Control:
This control sets the level of the page out of
the page control unit. The control should be
rotated clockwise to about 50% of its travel.
After setting control, the individual speaker
volume controls should be set to the desired
level.
2. All Call Level:
The All call level should be set to produce the
same audio level as the phone to speaker
page control. THIS ADJUSTMENT
SHOULD BE MADE AFTER INDIVIDUAL
SPEAKER LEVELS HAVE BEEN SET.
3. Background Music Levels:
There are two volume controls provided for
background music adjustments: Zones 1-5
and Zones 6-9. It is important that the two
background music controls be used to set the
music levels in the system. Adjust these controls
after all other system volume levels have been
