Federal Signal 300GCX-120 Selectone Speaker Amplifier

Product Description

The Federal Signal Corporation 300GCX-120 is a SelectOne combination speaker and amplifier unit designed for public address, alerting, and intercom applications in commercial and industrial facilities. It integrates the speaker and amplifier into a single housing, reducing installation complexity and component count. Licensed electricians and low-voltage systems technicians are the primary installers. The 300GCX-120 operates on 120-volt power and is sold as an individual unit, making it straightforward to specify for single-zone or multi-zone voice and tone communication systems.

This unit is suited for commercial buildings, industrial plants, warehouses, and institutional facilities that require a reliable wall- or ceiling-mount voice and alert speaker system. The integrated amplifier design makes it appropriate for new installations and direct replacement of existing SelectOne speaker-amplifier assemblies. It is typically installed as part of a broader paging, intercom, or emergency notification system where clear voice and tone output is required across a defined coverage zone.
