Setting up the door stopper alarm is as easy as sliding the power switch to the "On" position and placing the alarm at the foot of the door you want to monitor. If an intruder attempts to open the door, the wedge -shaped design will prevent it from opening and activate an above 90dB alarm. The alarm will scare off would-be intruders and alert you at the same time. With secure gripping ability, the alarm can function as a door stopper that prevents a door from being opened.
Dual Function: Alarm & Door Stopper.
This product is designed as a simple door stopper but can also function as an alarm system.
