Intercom - SM202
General Information

Duo-Com Master Station. Has built-in door chime and voice amplifier. Has momentary door release pushbutton. Surface mounts. Operates on batteries or 6VDC adaptor.
The Alpha Communications Duo-Com series intercom system is our lowest cost master/remote intercom for door entry or any other application requiring a single master and a remote intercom station. The SM202 master station has a built-in amplifier and electronic door chime. It can easily mount right on the surface of the wall (over a single gang electrical \’gem\’ box). A built-in momentary door release button allows hook-up to your own low-voltage door opener (depending upon trans-former used). The optional PK407A door opener relay allows connection to magnetic door locks or other \’fail-safe\’ type door openers. The SM202 is designed to be used with the OR202 remote station, but a wide variety of remote stations is available in ABS plastic, extruded aluminum, stainless steel, polished brass and painted finishes. The SM202 is available in a packaged kit form, along with the OR202 remote and 10 meters of connecting cable. Ask for our model #SM202K Duo-Com kit.
