SF117/2A and SF117/4A Emergency Pull Switch
- SF117/2A and SF117/4A Emergency Pull Switch
- The Alpha Communications® SF117/2A Emergency Pull Switch 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 SF117/2A provides two circuits to operate 1-2 signaling devices, such as a remote annunciator lamp, and a corridor dome lamp. An optional model (SF117/4A) provides two additional signaling circuits to operate additional options such as floor bell(s) and individual apartment electric door openers, as required. The SF117/2A features a rugged, long-life, positive-acting switch mounted on a flame retardant type ABS plastic faceplate marked "EMERGENCY" in Black lettering. In addition, the SF117/2A features our 'Exclusive' RED 'CallPlaced' Flag Indicator which gives positive visual assurance when a call is placed, without the need for any additional power or station wiring.2
