IS-3049BBM INSIDE SPEAKER STATION WITH CALL BUTTONS AND MICROPHONE

Same as the IS-3022BBM with electronics that allow parallel operation with other IS-3049's, (i.e. IS-3049's will listen together but their respective microphone will only be active when its own T/L switch is pushed.)   Brushed aluminum (2) two-gang with 2.5", 45 Ohm speaker, with push to talk, mute switches (gold switch contacts for longer switch life) and microphone.  Works great for stand alone control stations .
