Frequently Asked Questions - V-9970 Valcom

What is the Valcom V-9970 used for?

The V-9970 is a Single Zone One-way Station Level Page Control that provides paging access from a standard analog PABX station, C.O. line, or analog Centrex line. It uses DSP technology to transfer only speech, eliminating unwanted noises, and includes Automatic Gain Control (AGC) and background music input.

How do I connect the V-9970 to a telephone line?

Connect a single line phone to connector J2 using an RJ11C jack. The Tip and Ring from the phone line are connected to the terminal screws labeled PAGE OUT (for amplified speakers) or to the appropriate input. For detailed wiring, refer to the manual's Figure 1.

What power supply is required for the V-9970?

The V-9970 requires a Class 2 listed power supply. It can operate on -12VDC (using Valcom VP-412A) or on -24VDC NEC Class 2 power source. The unit draws 165 mA average (1 Watt) and up to 2 Watts during paging.

How do I adjust the background music volume?

The background music volume is adjusted by rotating potentiometer R13 clockwise for increased volume. Connect the music source to the terminals labeled 'SIG MUSIC' and 'COM IN'.

How do I set the dip switches on the V-9970?

Dip switches control various options. SW1 selects Silence Timeout (OFF) or Absolute Timeout (ON). SW2 enables/disables dial tone disconnect. SW3-SW7 adjust timeout durations. SW8 enables loop detect. Default settings: SW1=OFF, SW2=ON, SW5=ON (4 sec silence), SW8=ON. Refer to the manual's DIP SWITCH SETTINGS table.

What is the silence timeout feature?

Silence timeout causes the page adapter to hang up when the caller does not speak for a set period (1-31 seconds, adjustable via dip switches SW3-SW7). Default is 4 seconds (SW5 ON). This is enabled when SW1 is OFF.

What is the absolute timeout feature?

Absolute timeout forces the page adapter to hang up after a set period (4-124 seconds) regardless of whether the caller is speaking. This is enabled when SW1 is ON. The timeout duration is set by dip switches SW3-SW7.

How do I troubleshoot if the V-9970 does not page?

First verify that all connections are secure: power supply, RJ11C jack, and speaker connections. Check that the unit is properly mounted and the dip switches are set correctly. If the issue persists, test with a known working phone line. Call Valcom technical support at [phone] for assistance.

Is the V-9970 field repairable?

No, the V-9970 is not field repairable. Fuses are not user replaceable. If repairs are needed, tag the unit with company information and problem description, and send to: Repair and Return Dept., Valcom, Inc., 5614 Hollins Road, Roanoke, VA 24019-5056.

What are the disconnect options for the V-9970?

The V-9970 supports three disconnect methods: 1) Loop detect (default ON) - hangs up when caller goes on-hook; 2) Dial tone disconnect (default ON) - hangs up upon detecting dial tone frequencies (350/440, 440/480, etc.); 3) Silence timeout - hangs up after a period of silence. These can be configured via dip switches.

DESIGN

The Valcom V-9970 is designed to provide paging access from a standard analog PABX station number, a C. O. line or analog Centrex line. The Page Control incorporates the latest technology Digital Signal Processor (DSP) to recognize and transfer speech only, thus eliminating unwanted noises such as pops and tones. A discriminating Automatic Gain Control (AGC) is provided to make quiet pages louder and loud pages quieter.

The Single Zone One-way Station Level Page Control provides a music input with volume control for background music and an additional 1 Amp internal relay output (This input closes during a page to provide user page notification if desired).

INSTALLATION

The V-9970 Page Control must be powered by a Class 2 Listed, -12VDC output transformer or by -24VDC NEC Class 2 power source.

When using this equipment, basic safety precautions should be followed to reduce the risk of fire, electric shock and injury to persons:

1. Never install telephone wiring during a lightning storm.
2. Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
3. Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network.
4. Use caution when installing or modifying telephone lines.

Mounting/Connections

1. Remove the metal mounting plate from the rear of the V-9970 enclosure. Using two #6 3/4" wood screws, mount the plate in a vacant space on the backboard with the telephone system common equipment. Both mounting holes must be utilized to insure secure mounting of the unit.
2. Open the V-9970 enclosure to allow access to connections and option switches. Slide the rear of the unit (Contains the board) onto the mounting plate.
3. Using a 1/8" blade screwdriver, connect Tip and Ring from the Valcom amplified speakers to PAGE OUT on the V-9970 screw terminals.
4. Attach two wires from a music source output to the terminal screws labeled SIG MUSIC and COM IN. Volume is adjusted by rotating R13 clockwise.
5. A 1 Amp internal relay input is supplied to provide user page notification. Attach two wires from the notification equipment to the V-9970 if this feature is to be used.
6. Plug the RJ11C jack from a single line phone to connector J2 on the V-9970.
7. Connect 12V power supply (VP-412A) to connector J1 (If using the 24V option, connect the power supply to the terminals marked COM and 24V).
8. Set dip switches for desired options. (See chart following for settings).

Note: Dip switches for user options should be set for desired functions prior to replacing the enclosure cover and plugging in the power supply.

1. Replace cover and plug in power supply.

OPERATION

To make a page from a remote location, dial the phone number the page adapter is connected to and issue page. The background music will fade and the page will be heard through the amplified speakers. When the page ends, the music will resume.

Note: For most efficient operation, use Valcom VP-412A, 120VAC plug-in power supply.

DIP SWITCH TERMINOLOGY

The word "default" refers to the factory dip switch setting. Dip switches 2, 5 and 8 are set "ON" at the factory enabling silence timeout, dial tone disconnect and loop detect enable. The pager will "disconnect" after a page is made when the caller places the receiver on-hook thus dropping the current loop (Loop detect) OR by dial tone if the current loop detect is not passed through the telephone switching system (Dial tone disconnect) OR if silence is detected on the line for 4 seconds (Silence timeout).

Dip switch 1 OFF, "Silence Timeout Enable" means the Page Adapter will hang up when the caller does not speak for a period of time as selected by dip switches 3 through 7 (Dip switch 5 is default set to 4 seconds). Note the times can be added on the dip

switch settings. If dip switches 3 through 7 are set to OFF for no timeout, dip switch 1 has no effect and the timeout option does not occur. Dip switch 1 is default set to "OFF".

Dip switch 1 ON, "Absolute Timeout Enable" means the Page Adapter will hang up after a period of time as set by dip switches 3 through 7 regardless of silence from the person paging.

Loop Detect is factory set to the default setting of ON or enable which causes the V-9970 to "hang-up" when loop current is no longer detected signifying that the caller has hung-up. Sometimes the local telephone switch internal to the building does not pass this signal and then it becomes necessary to utilize other disconnect options.
