The Alpha Communications®/Tektone SF153N emer-
gency push station is used to initiate a system 'Emer-
gency' signal. It may be used independently or connected
with other call stations and/or intercom stations. It is used
primarily with the NC110A, NC110N, NC150N, NC150R or
NC200N series nurse-call systems.
Calling the nurse is accomplished by depressing the push-
button switch located at the center of the station to the 'IN'
position. This call cannot be canceled except at the point
of origin. Depressing the push-button again to the 'OUT'
position cancels the call. The station includes a lighted
'CALL-PLACED' L.E.D. indicator. The SF153N station
features a rugged stainless steel faceplate, with the word
'EMERGENCY' permanently stamped into the faceplate.
