virdi Posted February 10, 2009 Share Posted February 10, 2009 Hi all I'm going to attempt my first alarm install and the panel I've gone for is a Scantronic 9651 and 9940 or 9943 Keypads The alarm is going to be installed in a home garage - It's a garage at the back of my garden and is brick built, with a solid pitch roof. There are two doors and one electric up and over garage door - Size of the garage is around 26ft x 26ft Now obviously, I know that I should be going for Dual Tec PIRs - But there are so many makes and models and prices vary. I have seen Vantage Dual Tec's on eBay alot cheaper than others - So are these a good buy? Thanks Link to comment Share on other sites More sharing options...
james.wilson Posted February 10, 2009 Share Posted February 10, 2009 never heard of them so cant really say. But id look at the optex mx40, honeywell 7450 or 7550 and the rokonet iwise units securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

virdi Posted February 10, 2009 Author Share Posted February 10, 2009 Thanks Have you have good expeience yourself with the detector's you've suggested? As i've now read on here that the microwave part of a Dual tec can often pickup interference and hence cause false alarms? Link to comment Share on other sites More sharing options...
james.wilson Posted February 10, 2009 Share Posted February 10, 2009 only if not setup correctly or fitted in the wrong location. I have experience of honeywell and optex. Personally now id go for the honeywell if it were me. securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

virdi Posted February 10, 2009 Author Share Posted February 10, 2009 is it ok for me to have two Dual Tec PIRs that are covering the same area? Will the microwave or PIR sensors interfere with eachother? Link to comment Share on other sites More sharing options...
james.wilson Posted February 10, 2009 Share Posted February 10, 2009 No, it is possible if they are on exactly the same freq but most modern sensors dont have this problem securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
