When you cast the spell, you can designate creatures that won't set off the alarm. You also choose whether the alarm is mental or audible. A mental alarm alerts you with a ping in your mind if you are within 1 mile of the warded area. This ping awakens you if you are sleeping. An audible alarm produces the sound of a hand bell for 10 seconds within 60 feet.
