Jack b Posted June 4, 2018 Share Posted June 4, 2018 I've got a chubb alarm from the early 80s and it uses negative hold off but I want to connect it to a panel that uses positive hold off. How can I do this? Link to comment https://www.thesecurityinstaller.co.uk/community/topic/42132-old-chubb-alarm/ Share on other sites More sharing options...
sixwheeledbeast Posted June 5, 2018 Share Posted June 5, 2018 I suppose we are talking positive trigger. Invert the trigger with a few basic components or a transistorised relay maybe easier.
