virdi Posted February 11, 2009 Share Posted February 11, 2009 Hi all, Before I start playing with my new Scantronic 9651 - Please could somebody help or advise. I just want a simple explanation or diagram of how to wire a typical door contact please. (I'll be using 6 core cable) Thanks Link to comment Share on other sites More sharing options...
james.wilson Posted February 11, 2009 Share Posted February 11, 2009 You wire one pair across the contact and another pair across the tamper switch securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

virdi Posted February 11, 2009 Author Share Posted February 11, 2009 Thanks - And at the other end? Also - Why are there contacts that have 5 connections? Link to comment Share on other sites More sharing options...
miaren Posted February 11, 2009 Share Posted February 11, 2009 They are spare terminals used for connecting other wires e.g. for other zones. From memory the Scantronic manuals usually give very explanatory diagrams......not got one? Link to comment Share on other sites More sharing options...
virdi Posted February 11, 2009 Author Share Posted February 11, 2009 Yep - I have got one - But I didn't understand it properly Link to comment Share on other sites More sharing options...
lawandorder Posted February 11, 2009 Share Posted February 11, 2009 Yep - I have got one - But I didn't understand it properly Usually on standard surface or fush contacts there are 5 terminals, 3 are brass coloured and 2 are plated. The plated ones are the connections to the contact and the brass ones are spare. You will only need four cores for a contact, you twist two together and wrap them around one of the brass screws connect the remaining 2 to the plated screws.

How does the tamper work on a contact then? Would somebody have to damage it or rip it off the wall or door frame etc.. for it to trigger the alarm?

Thanks Yes the ones which connect to the brass screws are the tamper wires. Most simple contacts don't have a tamper swict fitted, the screws are there to terminate the wires but the tamper circuit is important as it protects the cable and will alert you if the wires are cut either accidentally or deliberately when the system is unset.

virdi Posted February 18, 2009 Author Share Posted February 18, 2009 Instead of twisting the two tampers wires and screwing into a brass screw - Could i use these two wires and take them to another contact? So it is ok having contacts without tamper wires connected? Thanks Link to comment Share on other sites More sharing options...
Guest RJBsec Posted February 18, 2009 Share Posted February 18, 2009 You can do what you like as its DIY but tamper is there for a reason and its not a good idea to bypass it ... if you do others will be able to as well. Link to comment Share on other sites More sharing options...
