Time sequence

Any will-independent alarm results in the transmission of the alarm to the personal
emergency signal centre as soon as the alarm condition occurs and the programmed
delay and pre-alarm time have expired. You can stop the transmission of the alarm if
you eliminate the alarm condition during the delay and pre-alarm time, or if you ack-
nowledge the pre-alarm during the pre-alarm time.

gency signal centre begins to initiate emergency
