Smart Shield Systems
IQ Shock-S
Detect forced entry at the source. The IQ Shock-S is a compact, wireless vibration + door/window contact that alerts your IQ Panel when a window or door is struck or opened. It adds adjustable shock sensitivity, S-Line encryption, and simple battery power—ideal for windows, sliding glass doors, and exterior doors.

Why Choose the IQ Shock-S with Smart Shield Systems
Dual protection: shock detection for blows/impacts plus a built-in reed switch for open/close monitoring (magnet included).
Fewer false alarms: on-device potentiometer lets us fine-tune sensitivity during install.
Secure wireless: S-Line encrypted 319.5 MHz communication to compatible IQ Panels.
Pro placement & testing from Smart Shield Systems for reliable, code-compliant protection.
Key Features
Multi-level vibration detection tuned for windows, sliding doors, and swinging doors.
Built-in contact with 1″ max magnet gap for normal open/close reporting.
S-Line encryption (rolling code) when paired with compatible IQ Panels; backward-compatible on legacy 319.5 MHz.
Supervision & tamper reporting with periodic check-ins to your panel.

Sliding glass doors and patio entries
Exterior doors that need both impact and open/close monitoring
Frequently Asked Questions
Where should the IQ Shock-S be installed?
Mount the sensor on the frame of the window or door you want to protect (including sliding glass and exterior doors), with the magnet aligned for proper gap. We’ll test placement and tune sensitivity during installation.
How do you set the right shock sensitivity?
During setup we tap the mounting surface and gradually adjust the potentiometer until the sensor trips for real impacts but ignores everyday vibrations (wind, blinds, etc.).
Does it include a door/window contact?
Yes. The Shock-S has a built-in reed switch and includes a magnet; keep the gap within 1 inch for reliable open/close reporting.
What battery does it use and how will I know when to replace it?
It uses a CR123A 3 V lithium battery. Your IQ Panel supervises the sensor and will alert you for low battery; replace with the exact type listed in the guide.
Is this model still available?
Availability can vary. Qolsys posts a discontinuation notice for IQ Shock-S in North America; the IQ Shock Mini-S is the current alternative in many deployments. We’ll check stock and recommend the right option.
