Why isn't my X10 SC1200 Security System PowerHorn tripping when the alarm goes off?

If the optional PowerHorn doesn't activate when the X10 Security System alarm trips, make sure the dials on the PowerHorn are set to the same SECURITY LIGHT code as set in the console and try plugging the PowerHorn into another outlet near the console.
