The popularity of personal alarms has always been around. They are simple to use even in a panic situation. They can be carried with you anywhere and can be used by anyone from the elderly to children (some grade schools and colleges even give them to all their students). Safety Technology has developed the Panic Pull Pin Alarm to make personal protection a priority. This item was made for easy activation with the ring-style pull pin. Even children and the elderly can slide their finger into the ring at the top of the unit to unleash a bright 350-lumen strobe light and ear-piercing 130 dB alarm that will scare off an attacker and summon help. The alarm can also be attached to keys with the included key ring, then simply pull down on the body of the alarm to activate it.
