Secware Posted March 28, 2014 Share Posted March 28, 2014 Risco beams 72 series (7225,7250 and 7275). The data sheet tells me what the tamper output is but not the alarm output ie if it a changeover relay, contact closure in alarm condition etc. Quote Link to comment Share on other sites More sharing options...
