Product Description

What you can do with this unit is add a warehouse bell or strobe indicator to your IP system without paying for those high priced IP connection devices.  Just hook up the RG-4 on any IP ATA port and it will power your bell ringer and an analog telephone as well.

Boost Ringing Power and Reshape Ring Signal to a True Sine Wave The RG-4 ring generator is designed to reshape and increase the ringing power of an existing telephone line, PABX extension, or any other telecom device which provides ringing. The RG-4 duplicates the incoming ring cadence allowing it to be compatible with custom ringing features. The RG-4 is capable of ringing four 1 REN or eight 0.5 REN telephones and does not affect normal operation of the telephone line or features provided by the phone company, such as caller ID and call waiting. The Viking model RG-10A may be used for higher drive output applications.
