The Alpha Communications® SM201K and SM201KP intercom kits are extremely economical master/remote intercoms for door entry or any other application requiring a single master and a single remote intercom station. The SM201B master does not have an 'auto shut-off' feature when monitoring the remote, so it can be used to monitor the remote for as long as required.
The master station has a built-in amplifier and electronic tone signal and it easily mounts right on the surface of the wall. A builtin momentary door release button allows hook-up to your own 16VAC (or other low voltage door opener (depending upon transformer/relay used). The outdoor remote station surface mounts directly on the wall, and requires only 2 wires.
Each kit includes 1- SM201B master station, 1- ES01S Aluminum outdoor remote station with included plastic surface box with built-in rainhood (and with separate EC105 capacitor) and 1- S1 special screwdriver. The SM201K includes a pigtail type 16VAC transformer (our model SS102A). The SM201KP includes a plug-in type 16VAC transformer (our model SS105B).
