The alarm continues sounding after activation until it is switched off with the remote or by approaching the alarm. The chime is described as sounding once.

Listing details to confirm

The listing has inconsistent kit details: it describes a two-alarm set with two remote controllers, six AA batteries, adhesive tape, screws and two instruction booklets, but the item details list one item, six AA batteries and an alarm user manual. Confirm the selected listing's contents. It also gives the alarm sound as 125 dB, the communication range as up to 328 feet, and PIR detection range as approximately 16–26 feet. These are listing claims, not independently verified measurements.

The aggregate rating is mixed, with a small number of ratings spanning the one- through five-star categories. It does not establish why people rated the product as they did, so it offers limited guidance on the claimed motion detection, alarm modes or remote operation.
