. . . for industrial telephone ringers, they are the #1 choice
Discontinued: no replacement
The Stinger 90, Model 196, operates directly from Central Office ringing. It has a modular plug that connects right into a standard telephone wall jack. A protected terminal block supports hard-wired installations. This unit is equipped with a three position volume switch (hi – med – low).
The Stinger 24, Model 198, operates from 24 VDC and a dry set of contacts. It does not connect directly to a phone line. It is ideal for use with our DSI-375 on MDC Centrex phones, or as a common audible or night bell on Key System installations. This unit is equipped with a volume control for continuous adjustment from zero to maximum volume.
