SF117/2C or SF117/4C
EMERGENCY CALL SWITCH
The Alpha Communications® SF117C 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 signal-
ing 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 open-
ers, 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.
