The EU311 micromodule range is designed for direct integration within devices to be controlled, thanks to its extremely compact size. The EU311 module features one supervised input and one loop-powered output, ideal for managing call points, sounders, or visual/audible indicators.
Variants include:

• EU311C: input only micromodule non-supervised for control of buttons, identifies on the Loop as a call point
• EU311CV: supervised input only, also identified as call point
• EU311S: output only micromodule for control of alarm signalling devices, identifies on the Loop as a sounder
