PI-1A Interface Your Paging System

Interface Your Paging System with Nearly Any Phone System!
Viking’s Telecom Paging Interface allows you to provide paging from nearly any phone system instead of from a microphone. You can also provide background music and an electronic night bell over the audio system.
The PI-1A features a built-in voice-activated (VOX) relay which provides DPDT contacts for muting background music during paging. The relay is also activated by AC ring for providing an electronic night bell. These contacts are necessary when interfacing with systems such as Panasonic, South Western Bell, Intertel, etc., which do not provide a paging contact closure.
In the event a paging port is not available, the PI-1A can provide a talking battery to allow connection of the public address system to an unused line/trunk input on the phone system.
The electronic night bell feature is activated by a standard ringing analog PABX/KSU station circuit or by a common audible contact closure provided by an electronic key system. The ring pitch and volume are adjustable allowing you to differentiate between multiple ringing lines.

Features

• Floating 600-ohm output
• Selectable 22V DC talk battery for interfacing with unused phone system line input/trunk ports
• Paging port interface
• Ringing analog line input for night bell
• Contact closure input for night bell
• DPDT normally opens and normally closed VOXactivated contacts for cutting out background music
• Adjustable VOX contact time-out
• Adjustable VOX trigger sensitivity
• Adjustable ring volume
• Adjustable ring pitch
• Wall mount housing, (2) #6 x ¾ Panhead screws included

Applications

• Integrate your public address system with nearly any phone system
• Cut out background music during a paging
• Electronic night bell from ringing line or contact closure
  Note: The PI-1A is not compatible with ring trip paging applications. See Viking models FXI-1A (DOD 494), PA-15 (DOD 486), or RAD-1A (DOD 410).

RETURNING PRODUCT FOR REPAIR
This procedure is for equipment that needs repair:

1. Customers must contact Viking’s Technical Support Department at 715-386-8666 to obtain a Return Authorization (RA) number. The customer MUST have a complete description of the problem, with information regarding the defect, such as options set, conditions, symptoms, methods to duplicate problem, frequency of failure, etc.

2. Packing: Return equipment in the original box or in proper packing so that damage will not occur while in transit.
   The original product boxes are not designed for shipping – an overpack box is required to prevent damage in transit. Static-sensitive equipment such as a circuit board should be in an anti-static bag, sandwiched between foam, and individually boxed. All equipment should be wrapped to avoid packing material lodging in or sticking to the equipment. Include ALL parts of the equipment. C.O.D. or freight collect shipments cannot be accepted.
   Ship cartons prepaid to VIKING ELECTRONICS

3. Return shipping address: Include your return shipping address inside the box. We cannot ship to a PO Box.

4. RA number on the carton: In large printing, write the RA number on the outside of each carton being returned.

RETURNING PRODUCT FOR EXCHANGE
This procedure is for equipment that has failed out-of-box (within 10 days of purchase):

1. Customers must contact Viking’s Technical Support at 715-386-8666 to determine possible causes for the problem. The customer MUST be able to step through recommended tests for diagnosis.
2. If the Technical Support Product Specialist determines that the equipment is defective based on the customer’s input and troubleshooting, a Return Authorization (RA) number will be issued. This number is valid for fourteen (14) calendar days from the date of issue.
3. After obtaining the RA number, return the approved equipment to your distributor. Please reference the RA number on the paperwork being shipped back with the unit(s), and also the outside of the shipping box. The original product boxes are not designed for shipping – an overpack box is required to prevent damage in transit. Once your distributor receives the package, they will replace the product over the counter at no charge. The distributor will then return the product to Viking using the same RA number.
4. The distributor will NOT exchange this product without first obtaining the RA number from you.
   If you haven’t followed the steps listed in 1, 2, and 3 above, be aware that you will have to pay a restocking charge.
