A: It requires 2× AAA batteries, which are not included in the package. Standard AAA batteries are widely available and affordable. Because it's battery powered, this alarm continues to work even during a power outage.

A: Yes! This sensor alarm is designed for use on virtually any door or window, including front doors, sliding patio doors, sash windows, casement windows, and more. Its compact, lightweight ABS body makes installation on different surfaces straightforward.

Q: Is this alarm easy to install without professional help?

A: Absolutely. The alarm is completely wireless and requires no professional installation. Simply attach the two components to the door/window and its frame using adhesive tape or small screws. The whole process takes just a few minutes.
