tsgek Posted April 12, 2015 Share Posted April 12, 2015 Anyone got any experience with the 8 output communicator on the Texecom Veritas Excel panels? Specifically I'd like to use them with a notification system which needs a 'voltage free' contact pair, from metering it I think it uses 3.3v and looks for it to be pulled low (to 0v) Simple solution seems to be a relay across the communicator outputs, but since these are designed as signalling outputs I'm not sure they'd be able to provide adequate current for switching the relay. There doesn't seem to be much documentation on these outputs, beyond what each pin does and it seems it can either be +13v (high) or 0v (low) depending on whether or not the output is active.

james.wilson Posted April 12, 2015 Share Posted April 12, 2015 I doubt they can sink enough to run a relay. You will need t relays Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

PSE Posted April 12, 2015 Share Posted April 12, 2015 The Excel panel outputs are rated at 100mA, You would drive a small relay from this to give you a volt free contacts Quote Link to comment Share on other sites More sharing options...

secureiam Posted April 13, 2015 Share Posted April 13, 2015 They didn't know, I find that hard to believe, but its in the excel and r8+ manuals without checking the exact page it would be under the communications section I suspect. If you get the pdf on the pc, search for it it is there.(well it used to be for sure). Quote Link to comment Share on other sites More sharing options...
