Overview

The Federal Signal TELH-120 Horn Extension Ringer is an industrial-grade device engineered to alert personnel of incoming analog telephone calls with powerful horn signals. Rated at 120 VAC, this device activates via the ringing voltage of analog telephone systems (40-150VAC, 16-60Hz) and delivers a piercing 100 dBa sound level at 10 feet (110 dBa at 1 meter), ensuring clear audibility in high-noise environments like factories, warehouses, and control rooms. The TELH-120 features a durable zinc die-cast housing with gray powder coat enamel and a Type 1 enclosure, meeting stringent durability standards for industrial settings. Certified by CSA and UL for indoor use, it provides reliable, immediate alerts without requiring visual indicators.
