The Alpha Communications® SF311G 'Geriatric' call cords are for use with various model patient stations in Alpha Communications®'s nurse call systems, including the model IR157N, IR257, IR258, IR311B, IR311C, IR312B and IR312C stations.
The call cord plug is inserted into the 8-pin (RJ45) receptacle located on the patient station, providing for call placement to the system master station. SF311G call cords are specifically designed for use in geriatric and oxygen environments but may be used in general applications also. To place a call, the patient need only apply slight pressure to the squeeze bulb using any body part. The force of air through the vinyl tubing closes a switch in the plug, thus placing a call.
An adjustable bed clip is supplied for the SF311G attached to each call cord.
