jeromephone 6 Posted December 3, 2006 I am trying to interface a gv-800 ver 8.0 with a keyscan access control system I have the io box and the relay board but when I look at the geo docs it tell how to output a relay to a set of pins to turn off either monitoring or alarms which is fine. the problem is how to you ractivate monitoring or alarms without going to the geo sever. What I want to do is have a valid user be able to come to a building which has monitoring and notification on and be able to resent his card which will let him into the building do what he needs to do and then present his card at the reader on the way out to reactivate the geo system. In other words I don't want the maintance guy to have any access or need to get on the geo system. Sorry for the long post Thanks Share this post Link to post Share on other sites
CollinR 0 Posted December 3, 2006 Elk has boatloads of relays and timers, they actually have one for door actuation. You will also find some problems in places that Geo is NO and you may need NC, Elk can fix that for you too. http://www.elkproducts.com/products/elk-960.htm Share this post Link to post Share on other sites
