The duration of a line calibration consists of a 45
second base time plus about 1
second per installed 'Voice alarm sounder beacon/Voice al. sound. beacon base'
device on the line to be calibrated. This means a line with 252 'Voice alarm
sounder beacon/Voice al. sound. beacon base' devices can be calibrated in about
5 minutes.
