Frequently Asked Questions

Where should the sensor and magnet go?

Mount the sensor on the fixed frame (door jamb or window frame) and the magnet on the moving portion. Keep the magnet within ¼″ of the marked sensor side; we’ll verify alignment during install.

What is the typical wireless range?

In open air it’s rated up to ~600 ft. Building materials can reduce range, so we test signal strength on site.

How long does the battery last and what type is it?

It uses one CR2 3 V lithium cell. The documentation recommends replacing it with the exact type about every 5 years; your panel will alert for low battery.

Can I get “door left open” notifications?

Yes. With Alarm.com we can enable left-open texts/push alerts and link the sensor to scenes (e.g., adjust thermostat if a window is left open).

Does it work with older systems?

It’s optimized for IQ Panels using S-Line encryption, but it can also enroll (unencrypted) with many 319.5 MHz legacy panels. We’ll confirm compatibility during your quote.

Ready for Rock-Solid Perimeter Protection?

Smart Shield Systems will place, enroll, and test your IQ Door/Window-S (QS1133-840), name zones, set chimes and alerts, and tie it into your automations—so you always know what’s open, closed, or left ajar.
