DOZE-Personal Alarm Doze Accessory
 
Connect this doze attachment to your Security Plus Personal Alarm, Protect-It Alarm or L.E.D. Alarm and place the ergonomically designed earpiece around the backside of your ear. If you start to fall asleep and your head nods forward or to the side, the alarm will activate, automatically resetting itself when your head is upright again.
