looking through the 2002 catalog i saw new portable PIR. from what i can tell it has an automatic reset, 30 sec. exit delay, and UP to 60 sec audio alarm(could be adj. shutter output???) has 50 ft. dist. and 9vdc. part # is 980-0282 if anyone smart would like to take a look at it and see what they think. price is higher than49-425, but could it be worth it?
