What Is a Chirp Locator?

---

A chirp locator is a device that identifies which smoke detector is emitting a low-battery chirp.

When a smoke detector battery gets weak, it signals a low-battery warning with a short chirp every 30-60 seconds. The sound echoes through ceilings and hallways, making it surprisingly difficult to figure out which alarm is actually beeping — especially in homes with multiple detectors.

A chirp locator attaches to each individual smoke detector. When that specific detector chirps, the chirp locator lights up — instantly identifying the exact unit that needs a battery replacement. No more walking room to room at 3am.

BeepFinder™ is the original chirp locator, designed for homes, apartments, and rental properties with multiple smoke detectors. Find it. Fix it. Sleep.
