Stinger Ringers . . . for industrial telephone ringers, they are the #1 choice

Installation Instruction
Product Brochure

The Stinger Ringer cuts through the noise of any environment with a powerful 110 dBA. Its intense signal is transmitted in all directions and reaches every corner of an industrial location or home.

The Stinger 24 (Model 198) operates from 24 VDC and a dry set of contacts.
The 198 does not connect directly to a phone line. The Stinger 90 (Model 196) does.

It is ideal for use with our DSI-375 on Meridian Digital Centrex phones, or as a common audible or night bell on Key System installations. This unit is equipped with a rotary volume control for continuous increase or decrease of volume.

The unit is housed in a rugged, light-weight aluminum weatherized case. The terminal strip is protected by a cover making the ringer ideal for indoor or outdoor installations.

If you work in a noisy or large area where the phones just cannot be heard, the Stinger Ringer is the ideal solution for you. Car lots, lumber yards, warehouses, noisy manufacturing plants, fire halls and farms would benefit from the Stinger Ringer. Note that a ring-detect relay such as Model 173W is required to activate this model from the ringing of one or more analog phone lines. See Stinger 90 for single-line applications.

Connect a doorbell button or door-open switch across the contact pair to alert the shop when a customer arrives.

The Stinger Ringers have proven themselves to be economical, labor saving and extremely effective in a variety of applications. They have been successfully installed in applications ranging from noisy industrial areas to home use for the hearing impaired.
