SED-SRIS ( ring indicator system )
Ring Generator Kit

The SED-SRIS is a telephone ring generator system used to simulate a ringing telephone. This product microprocessor-based controller is designed to provide a ring cadence tone and voltage that simulates a telephone ring when 12v DC is applied. The system is smart enough that it can sense off-hook detection and then cancel the ring generation once the handset is lifted.

  • Voltage input 12-15v DC

  • Output 45v DC

  • Cadence is modulated to simulate a ring tone

  • Housed in a plastic enclosure 

  • Size: 30 x 45 x 70mm

  • Telephone hand set supplied as shown with ring gen kit
