Frequently Asked Questions

How high should it be mounted?

The datasheet recommends about 7.5 ft (2.3 m) for best coverage and pet-immunity performance.

Will my pets set it off?

You can select 33 lb or 55 lb pet-immune modes. We’ll choose the right setting and angle the sensor to avoid pet pathways (keep pets out of the look-up zone).

How often does it check in?

It sends a supervisory signal roughly every 70 minutes, plus alerts for tamper and low battery.

What battery does it use and how long does it last?

A single CR123A 3 V lithium cell. Life is typically multi-year depending on traffic and temperature; your panel/app will warn when it’s low.

What’s the real-world range?

Open-air spec is ~350 ft; actual range depends on construction and panel placement. We perform a walk-test and RF check during installation.
