Dave I need to set up a similar sys in my barn. can you explain your setup. Please!
The detached garage [in my setup] was only about 50 feet from the house...within range of the DS10A's. If your barn is further from the house the console will likely need to mounted in the garage. Of course... that would mean power and phone lines would need be in the barn as well. But then you can still add a siren, lamp module, or even a chime in the house.
Directions for setting the code for the flashing/blinking light code are in the alarms direction.. it is nothing special. Whichever House code you select for the alarm... the number one unit.. will flash/blink.
The Floodlight (PR511) has other cool features that I like as well (its the heart of my outside setup). The floodlight can turn on up to 4 other devices when it senses motion (and 4 more at dusk/dawn). So you can use the floodlight to detect motion around the barn... and then chime a chime... or light a light inside the house, to alert you. I use an X10 floodlight to turn on a light, chime, and
CAMERA... which then automaticlly displays on my TV.
