The 209 adapter is designed to use in our 12 Gauge perimeter trip alarm in lieu of a blank or flash bang. The adapter slides into the grooves on the bottom of the device. We recommend to use a reliable brand like CCI Shotshell Primers but all 209 primers will work in the device. Once the 12g perimeter trip alarm w/209 adapter is armed, then triggered, it will produce around 124dB with a flash.
