The Ring Booster is designed to solve problems where telephone devices will not Answer.
The Ring Booster incorporates two RJ11 (6 pin) telephone line ports and a 12V power input port. It is supplied with a 12VDC/500mA power adaptor, but it can also operate with a 12VAC or other 12VDC input (either polarity) with a min of 500mA.
When an incoming ring is detected on the line input port of the Ring Booster, it will immediately output amplified Australian, US or UK (switch selectable) ring cadence via the line output port, sufficient to typically ring an additional 3 or 4 devices.
The Ring Booster will then cease its amplified ring output as soon as any device connected to the line output port answers the incoming call.
