The Alpha Communications® E-144 Emergency
Pull station is used to initiate a system 'Emergency'
signal. It may be used independently or connected
with other call stations and/or intercom stations.
The E-144 has a spring loaded switch that activates
in a 'Momentary' fashion, only as long as the pull
cord is pulled.
Placing a call is accomplished by pulling on the pull
cord. This type of 'Momentary' is usually canceled
except at the master annunciator station(s). The E-
144 station features a rugged stainless steel face-
plate, with the word 'EMERGENCY' permanently
silk-screened onto the faceplate.
