This door knob alarm is a dual purpose 120db alarm. It acts as a burglar alarm and a personal alarm. Hang it on any door knob (non-metallic doors) and it instantly and automatically sounds when an intruder touches the door knob.
The 2-in-1 door knob alarm may also be placed in hand, pocket, or handbag with the attached metal chain wrapped around the wrist so that if the user is being attacked, or the handbag is snatched, the metal chain is automatically pulled out and the alarm is instantly activated.
You can pull the chain out yourself if you feel threatened. Doing so will alert others in the area that you need help.
The loud piercing siren will continue sounding until the metal chain is plugged back in. Uses one 9-volt battery (not included).
- Sounds instantly when an intruder touches the door knob
