Frequently Asked Questions - V-9936A Valcom

How many lines can the V-9936A monitor?

The V-9936A monitors up to six C.O. lines or PABX station numbers. Up to four units can be multiplied to monitor 24 lines.

What type of power supply is required?

The unit requires a -21.5 to -26VDC 'B' battery supply, drawing up to 200 mA. The Valcom VP-624B or VP-4024C power supplies are recommended.

Can the V-9936A be used with a paging system?

Yes, it can be connected to one zone of a Valcom one-way or talkback paging system, or to a high-power amplifier. The ring tone will override any page in progress.

How do I connect a night switch?

Connect a switch between pins 9 (disable input) and 24 (ground). When the switch is closed (short), the V-9936A is disabled, allowing night silencing.

What are the output options for signaling?

The V-9936A provides two outputs: a warble tone (interrupted) for speakers, and a dry contact closure (rated 1A @ 105VAC or 2A @ 24VDC) for bells, strobes, or other devices.

How do I adjust the volume?

The unit has a built-in volume control. Adjust it to the desired level while a line is ringing. Also set the Speaker Select Switch to Hi Z for 45 Ohm talkback speakers or Lo Z for one-way amplified speakers.

What should I do if the power reversal LED is lit?

Unplug the power supply and reverse the connections on pins 29 (GND) and 30 (-24VDC). Replug the power supply; the LED should turn off.

How do I multiply units for more than 6 lines?

Connect a wire from pin 8 (expansion) of the main V-9936A to pin 8 of each additional unit. All units will then ring together when any monitored line rings.

What is the maximum distance from power supplies?

Do not locate the V-9936A or its wiring closer than 18 inches (45.7 cm) to a power supply or any equipment that generates electrical noise.

Is the V-9936A field repairable?

No, the unit contains no user-serviceable parts. If repairs are needed, contact Valcom technical support at [phone] or return the unit to Valcom, Inc. in Roanoke, VA.

DESIGN

General

The Valcom V-9936A is designed to monitor up to six C. O. lines or PABX station numbers and will provide a common tone signal and contact closure whenever any of the lines are ringing. The V-9936A may be used with most telephone systems because it connects directly to the lines and not to the phones.

The tone output may be connected to speakers used only for ringing or to one zone of a paging system. The dry contact closure may be used to activate loud ringing bells, strobes or other external equipment. Both outputs will provide interrupted signals whenever any line is ringing.

A disable input is provided for connection of a night switch. With no switch connected, the V-9936A will signal any time a line rings in. With a switch connected and providing a short across the disable input, the unit will be inactive.

Stand-Alone Ringing

The following components are required to provide common audible ringing over dedicated bells or speakers.

• V-9936A C. O. Ring Units, 1 per 6 lines
- Signaling Devices consisting of: a. Two 45 Ohm talkback speakers or b. Up to 150 one-way amplified speakers or c. Loud bells, buzzers, strobes etc. as required

- Power Supply: The VP-624B will power a V-9936A using talkback speakers for signaling. If one-way speaker assemblies or other signaling devices are used, additional power may be required.

Ringing Over Paging

Ringing may be connected to one zone of a Valcom One-way or Talkback Paging System or to the INPUT of a high powered amplifier. The following components are required:

• V-9936A C. O. Ring Units, 1 per 6 lines
- VP-624B -24VDC Power Supply (VP-4024C if using more than (3) V-9936A's).

If a page is in progress when an incoming call is detected, the ring signal from the V-9936A will momentarily override the page.

FIGURE 1 - TYPICAL INSTALLATION

INSTALLATION

The following sections contain step-by-step instructions for wiring the V-9936A and associated Valcom equipment. Each instruction is preceded by a line; place a check on the appropriate line as the instruction is completed. The instructions also include tests along the way to verify connections have been made correctly. If these steps are followed exactly, installation should go smoothly and quickly. If the results of a test do not correspond with what is shown, DO NOT PROCEED UNTIL THE PROBLEM HAS BEEN CORRECTED.

Set individual volume controls at approximately 1/2 volume for testing when installing the control unit and any one-way amplified speaker assemblies.

Mounting

Remove the metal mounting plate from the rear of the V-9936A enclosure. Using two #6 x 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. See Figure A. Open the V-9936A enclosure to access connections and option switches. Slide the rear of the unit (Contains the board) onto the mounting plate and lock in place with screw provided. Make connections and replace cover after all connections are accomplished. Lock cover in place using the #6 x 1/2" screw provided.

FIGURE 5 - CONNECTIONS FOR A TELEPHONE SYSTEM WITH A COMMON AUDIBLE CONTACT CLOSURE

OPERATION

When a line rings in, the control circuitry and timer are activated. While sensing the first incoming ring, the unit will activate the output relay, disconnect the page source and send a one second warble tone and dry contact closure to the output. The relay will then drop and paging will be reconnected. If additional incoming rings are sensed during the next 4 seconds, a second tone and closure will be sent. One second tones and closures will then be sent every 4 seconds for as long as ringing is sensed on any line. If several units are connected together using the expansion leads, all units will send tones if a line rings in on any unit. Connecting the disable lead (pin 9) to ground (pin 24) will prevent the unit from being activated. Connecting a switch between these pins will allow use of the V-9936A for night ringing. A simplified schematic of the V-9936A is shown on the next page.

TECHNICAL ASSISTANCE

When trouble is reported, verify power is being supplied to the unit and there are no broken connections. Check voltages for proper polarity on the cross connect block. Table 1 identifies symptoms of some possible problems with solutions. If a spare unit is available, continue to troubleshoot by substituting the spare unit for the suspected defective unit.

Assistance in troubleshooting is available from the factory. When calling, you should have a VOM, several clip leads, a telephone test set available and be calling from the job site.
