Example 7: Announcing Alarms over a Public Address System
In this example, the B1290 is used to announce alarms from an unattended
location over a building’s public address system. You want the alarms to be
announced twice, repeated again one minute later then repeated for the
last time one minute after this. To make the process stop after the third rep-
etition, program Timer B to zero. A zero value in Timer B means that the
alarm is automatically acknowledged after A Times.
Connect the radio port, TX Audio and PTT, from the B1290 to the PA in-
puts.
