This personal alarm combines two great deterrents: a loud alarm and flashing light. Once the cord is pulled out it will activate the 130 DB alarm and flashing light. Since there are four different attachments as well as a belt clip, there are many different ways this alarm can be used: Keychain and laynard attachment allows you to carry it in a purse or pocket. When the cord is clipped to your belt or wrapped around your wrist and the alarm is placed inside your purse, briefcase, or backpack, the alarm will sound if someone attempts to take it from you. The alarm can be instantly converted into a door or window alarm using the included door clip accessory. Opening the protected door or window will activate the alarm and flashing light.

Comes with a 9 volt battery.
