andyh747 Posted January 29, 2012 Share Posted January 29, 2012 Panel: Scantronic iON40 I need to utilise an additional voltage free output to control an electronic water control valve from the panel. The water panel utilises a voltage free contact which can be either NO or NC. The problem is that the iON 40 only has two voltage free outputs which already used for the siren and strobe. Ouputs 3 and 4 are transistorised outputs giving 12v when inactive and 0v when active although this can be changed on the panel. My first idea is to utilise a 12v dc relay which is fed by output 3 with the contacts from the water panel connected to the relay output. Any other suggestions?

fozzies Posted January 29, 2012 Share Posted January 29, 2012 I'd say the relay was the right way to do it. Link to comment Share on other sites More sharing options...
Amps Posted January 29, 2012 Share Posted January 29, 2012 Put the strobe onto the bell output? Link to comment Share on other sites More sharing options...
andyh747 Posted January 29, 2012 Author Share Posted January 29, 2012 Put the strobe onto the bell output? I had thought of that idea but the panel has the ability to activate the strobe on alarm set. Obviously this would then also activate the siren if it was on the same contact. I currently use this feature as a visual clue that arming has been successful. However if I disabled this then I could put them both on the same output. I think the relay sounds the best option.

fozzies Posted January 29, 2012 Share Posted January 29, 2012 Depends on the current rating of the output as to whether u can double up strobe and bell o/p. relay is best/safest option Link to comment Share on other sites More sharing options...
james.wilson Posted January 29, 2012 Share Posted January 29, 2012 as above use a relay or use the other outputs to run the bell / strobe and free up the voltage free ones securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Could this be moved from the voltage free contacts to the transistorised contacts without problem? Link to comment Share on other sites More sharing options...
james.wilson Posted January 29, 2012 Share Posted January 29, 2012 yes assuming the outputs can sink enough. What are they rated at? securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.
