Guest gowron Posted August 26, 2004 Share Posted August 26, 2004 Hi everyone, I'm not an installer but is was wondering if anyone can answer this question: I have a Scantronic 9448M control panel to which i like to connect two smoke detectors. The smokes deliver +12V on their status output when triggered. Zone 5 on the panel can be programmed to be used for fire alerts. Now for the question: How can i connect these detectors to the zone input of the control panel? Do i need some sort of relais between the detector and controlpanel? If you know the answer please let me know (with a small schematic?) Thanks in advance Eric Link to comment Share on other sites More sharing options...

Guest gowron Posted August 26, 2004 Share Posted August 26, 2004 Eric are these specific security system smokes or general ones. 21676[/snapback] I think their normally used with fire panels and security systems. I don;t know the exact type but they are from Ajax (hexatron or something like that). They look rather professional. Link to comment Share on other sites More sharing options...
Mister_Dave Posted August 26, 2004 Share Posted August 26, 2004 Im not 100% sure but i dont think these are compatible with the 9448. I always use the exodus range from texecom. Dave Oxendale York based security systems engineer. Link to comment Share on other sites More sharing options...
BUSTER Posted August 26, 2004 Share Posted August 26, 2004 You need 12v versions with a normally closed connection Any comments / opinions posted are my opinion only and do not represent those of my employer or Company Link to comment Share on other sites More sharing options...
breff Posted August 26, 2004 Share Posted August 26, 2004 you could use the 12v output to drive a mini relay with the nc connected across the zone The opinions I express are mine and are usually correct! (Except when I'm wrong)(which I'm not) Link to comment Share on other sites More sharing options...
Guest gowron Posted August 26, 2004 Share Posted August 26, 2004 Thanks guys, i think i will dump the ajax smokes and go for the texecoms Link to comment Share on other sites More sharing options...
