SS201 Clean Room Membrane Type Master Stations

The SS201 is a simple one to one communication system designed to be used in a sterile environment. The antibacterial membrane inhibits the growth of bacteria, mold and mildew. It is resistant to chemicals and household cleaners and the station is designed to be water tight when used with a proper 3 gang electrical back box BBF910 (for flush mounting) or BBS910 surface back box.

The convenient 'simplex' operation allows the operator to push the TALK button when they need to talk and release to listen. When the conversation is over, either party can cancel the call by pressing the CANCEL button. The LED turns red when in the LISTEN mode and green in the TALK mode, so from a distance, one can see if the station is ON. There is a separate speaker and microphone for crystal clear intelligibility. The stations are designed for an optional headset and foot switch.

Where required, the SS201 can also be used with the SS200 (Stainless Steel faceplate) desk/wall master station. 

When used with the RM5000EX or CB901EX systems, the SS201 can be used in a larger capacity system.
