Abstract
An audible alarm is provided for use in an alarm system which produces a plurality of distinct audible alarm signals in response to a control signal. The audible alarm can further produce a prerecorded voice message which can be stored at the audible alarm. A microcontroller at the audible alarm controls the audible alarm in response to the control signal which can be received from a control panel over a pair of lines. The control panel further supplies power over the pair of lines.
