Question 1

What is the best wireless shock sensor for forced-entry detection?

Accepted Answer

For catching a break-in before entry, the best wireless shock sensor has adjustable sensitivity, mounts on the door or window frame (not the glass), and reports over a fully supervised wireless zone on your panel's frequency. The Versa SHOCK-319 delivers all three — a 319.5 MHz dual shock sensor and door/window contact on one zone, adjustable sensitivity with green pre-shock and red alarm LEDs, a 5+ year CR2U battery, and UL/FCC listing — for the Qolsys IQ Panel 4, IQ Panel 2+, and GE/Interlogix 319.5 MHz panels.

Question 2

What is a shock sensor and how is it different from a motion detector?

Accepted Answer

A shock sensor is a forced-entry vibration detector that mounts directly on a door or window frame. It detects the physical impact and vibration of a break-in attempt — prying, kicking, or drilling — and triggers before entry occurs. A PIR motion detector is a passive infrared sensor that detects body heat movement inside a room, triggering after an intruder has already entered. They solve different problems: shock sensors protect the perimeter at the point of attack; motion detectors provide interior coverage. The Versa Wireless SHOCK-319 is a shock and vibration sensor — it is not a glassbreak detector, which is an acoustic device that listens for the sound of shattering glass.

Question 3

Can a shock sensor also act as a door/window contact?

Accepted Answer

Yes — the Versa Wireless SHOCK-319 is a dual-purpose sensor. It includes both a shock detector and a built-in reed switch (door/window contact). A DIP switch controls the reed function: set to ON, the sensor acts as both a shock detector and a door/window contact using the included magnet. Set to OFF, it operates as shock-only without the reed contact. This lets installers use one device to protect both the door/window contact zone and add shock detection on the same frame — reducing hardware count and installation time.

Question 4

What panels is the Versa SHOCK-319 compatible with?

Accepted Answer

The SHOCK-319 operates at 319.5 MHz and is compatible with Qolsys IQ panels (IQ Panel 2+, IQ Panel 4 with 319.5 MHz SRF card), GE/Interlogix systems, and other 319.5 MHz alarm panels. It is not compatible with DSC 433 MHz or Resideo 345 MHz panels, which use different frequencies. For DSC-compatible shock coverage, check Versa's expanding 433 MHz sensor line at versawireless.com.

Question 5

What Versa Wireless sensors are compatible with DSC classic PowerSeries panels?

Accepted Answer

Versa Wireless is expanding its 433 MHz sensor lineup for DSC PowerSeries (PC1832, PC1864, Impassa, Alexor) compatibility. The MINI-433 door and window contact is designed for 433 MHz DSC panels. For Qolsys, GE/Interlogix, and 319.5 MHz panels, Versa offers the SHOCK-319 (shock sensor + door/window contact), PIR-319 (PIR motion detector), and MINI-319 (door/window contact) — all at 319.5 MHz.
