Frequently Asked Questions

What’s the difference between the IQ Mini and the IQ Mini Extended?

Functionally similar, but the Extended version adds screw-terminal inputs for a nearby NC wired contact—handy when the wireless body can’t sit right at the opening.

How far can I run the external leads?

Keep the external contact’s lead length at or under 20 ft, per the quick-install guide.

What magnet gap should I expect?

When aligned correctly, the guide specifies a maximum gap of about 3/4″ between sensor and magnet.

What batteries does it use and how long do they last?

Two CR2032 coin cells. The product page cites up to 8–10 years of life, and the quick guide recommends replacing with the exact type about every 5 years; your panel will alert for low battery.

Will it work with my IQ Panel?

Yes—if your system supports 319.5 MHz sensors. It uses S-Line encryption with compatible IQ panels and is backward-compatible with many legacy 319.5 systems. We’ll confirm firmware during your quote.

Ready for a Tidy, Flexible Contact Install?

Smart Shield Systems will design placement, wire the external contact (if needed), enroll your IQ Mini Extended (QS1137-840), and set up the right notifications and rules—so you always know what’s open, closed, or left ajar.
