Two Stage Alarm
When a two stage alarm is required it is possible to activate an alternate tone
by connecting the “♫/☼” (Beacon ground) pin to 0v (as detailed in the table on
page 5).
For this application, a barrier with 2 Diode return paths is required as shown in
the diagram below:
Switching between return paths for the 2 stage system will enable the 2nd tone.
Second stage tone can be found in the table on page 12.
