The SF118C Emergency Switch is available in two models. The SF118/2C provides two contacts, one to signal a dome light and master station, and one to signal a buzzer or DC bell. The SF118/4C provides two additional contacts that may be used to operate additional signaling devices as needed.

Both models feature a rugged, long-life, positive-acting switch mounted on an attractive, flame retardant (UL 94V-0) plastic faceplate marked emergency that includes a red LED. Signaling an emergency requires just a short pull in any direction on the 6? long nylon cord. The signal cannot be canceled except at the point of origin.
