Versa SHOCK-319 Wireless Door/Window + Shock Sensor 319.5 MHz Bluefield LED, Adjustable Sensitivity, 5+ Year CR2 Battery

Professional-Grade Door/Window + Shock Sensor Built for Installers The Versa SHOCK-319 is a 319.5 MHz wireless sensor that combines door/window contact monitoring with adjustable shock detection in one compact, surface-mount package. Designed for alarm installers and security professionals, it drops into any Qolsys, GE/Interlogix, or ELK 319.5 MHz system with zero complications. Versa's Bluefield technology sets the SHOCK-319 apart with three-color LED feedback: Blue confirms magnet alignment during install (active for 5 minutes after battery install or cover removal), Green flashes on pre-shock vibrations to help dial in sensitivity, and Red signals a shock alarm in progress. No other 319.5 MHz sensor offers this level of real-time visual feedback. The built-in DIP switch gives installers control over how the shock and reed switch interact. Set it to ON and shock only triggers when the door or window is closed. Set it to OFF and shock stays active regardless of position. Adjustable sensitivity via a dial lets you fine-tune detection for each site. Powered by a single 3V lithium CR2 battery (Versa CR2U or Panasonic CR2) lasting 8+ years. Slide-off lid for tool-free battery and DIP switch access. Tamper detection alerts the panel if the sensor is removed. Dimensions: 2.85" x 1.15" x 0.75". Magnet gap: 1" wood / 1/4" metal. Operating temp: 32122°F. UL listed (door/window contact function), FCC and IC certified. Shock sensor detection is not evaluated by UL. 2-year manufacturer warranty.
