the switch signals an administrator to establish a call through a two-way speaker.
When pushed and released four times, the switch initiates an emergency call at the
administrative station.The switch has a privacy feature which prevents monitoring
from the administrative station.The privacy function does not interfere with the
ability of the administrative station to call the staff station, however, the privacy
switch must be released in order to respond to a call.
