Teledata manufactures the Teledata One family of addressable fire alarm control panels at Cernusco sul Naviglio outside Milan — expandable to nine loops and 2,160 addresses, mixing wired and wireless loop devices — together with detectors, modules and the OneCloud compliance management software. The company states the panel is the first with touch-screen technology certified to EN 54-2 and EN 54-4, and publishes the EN 54-2 and EN 54-4 certificate alongside EN 54-13 system and system-auxiliary certificates on its certification page. That page carries the marks of IMQ, LPCB, EVPU, Accord and the Singapore Standards Council. The certificate numbers sit inside the linked documents rather than in the page text, so none is quoted here.
