Mace® Brand Personal Alarm Heart
The Mace® Brand Personal Alarm Heart features an alarm that is heard at 120dB. That is the equivalent of a police siren! The Personal Alarm Heart has an attached key chain so you can carry it with you at all times. Simply pull the grenade-style pin (attached to the key chain), and this ear-piercing alarm will activate for up to a half hour of continuous sound. Activating the alarm switches the element of surprise from the attacker to the potential victim. Replacing the pin is the only way to silence the alarm. The alarm is equipped with three LR44 batteries and ready for use after the battery tab has been pulled. There is also a test button on the back of the alarm for you to ensure your alarm has battery life.
