xpertalarms Posted August 1, 2019 Share Posted August 1, 2019 Hi all Currently having issues with the speaker input on a twin alert. It's wired to a GD48 and all is working apart from the speaker input for ee horn tones. I've connected it to the speaker negative (and tried positive) to no avail, anyone else had issues when using a dimension? Can I use a programmable output instead? I was under the impression that the speaker input of the twin alert wasn't designed to be fed DC so being a bit wary! Even pyronix tech support were scratching their heads. Cheers Quote Link to comment Share on other sites More sharing options...

xpertalarms Posted August 1, 2019 Author Share Posted August 1, 2019 Neg side of speaker (horn) output Quote Link to comment Share on other sites More sharing options...

xpertalarms Posted August 1, 2019 Author Share Posted August 1, 2019 Yep, tried a 2k2 resistor as per the manual Quote Link to comment Share on other sites More sharing options...
james.wilson Posted August 1, 2019 Share Posted August 1, 2019 Use an output programmed as ee horn. Or a proper speaker.

Hate those twin alert things Fine for domestics imo but prefer the soint2. Can a programmable output be used then? The manual isn't very clear!

As James said use output programme as ee horn but you would be connecting that to a sounder of sorts I think Quote Link to comment Share on other sites More sharing options...
datadiffusion Posted August 2, 2019 Share Posted August 2, 2019 (edited) I used to use them resistorless on scanny domestics but don't any more - have you tried any other value of resistor e.g. 10k (or 2 x 4.7 ) Edited August 2, 2019 by datadiffusion Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands Link to comment Share on other sites More sharing options...
xpertalarms Posted August 2, 2019 Author Share Posted August 2, 2019 Popping back there to look at it this afternoon so will try it and let you know how I get on. Yes, tried some different resistor combos 4k7 and 1k Quote Link to comment Share on other sites More sharing options...
