SM201B / SM201BTS Master Stations

The Alpha Communications® / TekTone SM201B series intercom system is an economical master / remote intercom for door entry or any other application requiring a single master and a single remote intercom station.

The SM201B master station has a built-in amplifier and tone signal generator. It can easily mount right on the surface of the wall (over a single gang electrical 'gem' box), or onto an optional IH400A desk cabinet. A built-in momentary door release button allows hook-up to your own 16VAC or 24VAC door opener (depending upon transformer used). The optional PK407A door opener relay allows connection to other voltages and types of door openers. A wide variety of remote stations is available in ABS plastic, extruded aluminum, stainless steel, polished brass and painted finishes.
