The Apollo 55000-847APO XP95 Input/Output Unit is a loop-powered addressable interface for Apollo XP95 fire detection systems. It gives a volt-free, double-pole changeover relay output to control plant or equipment, a monitored switch input and an opto-coupled input, and has a short-circuit isolator built in as standard. It is supplied with a backbox for surface mounting.
