ENTERLOK^TM provides two-way natural voice communication from a master to remote (or vice versa). It has a total capacity of two (2) stations (1 Master, 1 Remote). The SM-201’s TALK and LISTEN controls provide the master with privacy and discreet handsfree monitoring for improved security.

Low cost SM-201 master has a built-in voice amplifier, volume control, electronic tone signal, TALK, LISTEN and electric DOOR release (or other signalling device) buttons. Install the SM-201 on a standard 1 gang electrical box, or use our popular IH-400A cabinet for desk or surface mounting.
Easy 2-wire hook-up!
As you’d expect from LEE DAN^®, ENTERLOK^TM has a selection of over 20 remotes, including indoor, outdoor, vandal-proof, and patio horn styles. Remote stations are available with or without a call-in button to signal the master, and for flush, surface or desk mount use. Only one (1) pair of twisted wire is needed between the master and remote speaker.

Efficient low-voltage design allows convenient hookup by do-it-yourselfers with our UL listed model PS-20A plug-in transformer.We take great interest in the special security needs of our customers, and great pride in the quality of our products!
