Federal Signal Models AM300GCX and AM302GCX are rugged, transformer coupled, re-entrant speakers for use 

in public address or paging applications. These speakers feature rugged cones and projectors constructed of spun aluminum. The wiring connections are enclosed in a dust- and moisture-proof, die-cast aluminum compartment. All external surfaces are finished with a red or gray powder coat paint. 

The unique shape of the speaker projectors provides an impressive 60° sound dispersion pattern. The projectors are held in position with a Teflon coated lock ring that can be rotated 180° in order to obtain the desired sound distribution.

The AM300GCX and the AM302GCX can be used supervised alarm notification systems or CTS series amplifiers and the AudioRouter™ to complete an industrial grade public address system.
