SF117/2C or SF117/4C Emergency Call Switch

The Alpha Communications® / TekTone SF117/XC Emergency Switch is available in two models and features a rugged, long-life, positive-acting switch mounted on a durable ABS plastic faceplate. Signaling an emergency requires just a short pull on the 6' long nylon cord, in any direction. The signal cannot be canceled except at the point of origin.

The SF117/2C provides two circuits to operate 1-2 signaling devices, such as a remote annunciator lamp, and a corridor dome lamp. The SF117/4C provides two additional signaling circuits to operate additional options such as floor bell(s) and individual apartment electric door openers, as needed. Both models feature a rugged, long-life, positive-acting switch mounted on a flame retardant type ABS plastic faceplate marked "EMERGENCY".

If a 'call placed' or 'call assurance' capability is required, we recommend that you use our SF118 series pull cords, which have a built-in Red L.E.D. 'call placed' indicator, or our SF117/2A, SF117/4A, SF119/2A and SF119/4A series pull cords with a built-in mechanical Red call placed indicator.
