Frequently Asked Questions

Where should the sensor and magnet go?

You can mount the sensor at the top or on the side of the door; the magnet mirrors that placement. In some door types it’s better to place the sensor in the frame instead of the door—our tech will choose the best option.

How often does it check in with the panel?

About every 70 minutes (supervisory keep-alive), and it also reports tamper, alarm/restore, and low battery events.

What’s the wireless range?

Listed up to 600 feet (open air). Actual range depends on construction; we verify signal strength during installation.

What battery does it use and when do I replace it?

One CR2 3 V lithium cell. Replace with the exact type approximately every 5 years; your panel/app will alert you for low battery.

Will it work with my IQ Panel?

Yes—if your panel supports 319.5 MHz sensors. S-Line encryption is used with compatible IQ panels and remains backward-compatible on legacy 319.5 MHz systems. We’ll confirm firmware during your quote.

Ready for Invisible Door Protection?

Smart Shield Systems will drill and fit your IQ Recessed DW-S (QS1134-840), enroll it to your panel, and set up chimes and alerts—so you get discreet security that blends right in.
