or Hands Free Cycler function optional). To have
the AUX function instead activate when Terminal
1 is connected to ground (negative), flip DIP
switch #1 into the DOWN (On) position (as
pictured to the right).
DIP Switch 2 -
Hands Free Cycler Mode Enable
This siren is shipped with the Hands Free Cycler mode DISABLED. To
enable Hands Free Cycler mode, set DIP switch #2 into the DOWN
(On) position (as shown to the right).
