FlexES Control esserbus module

Single loop modules for up to 127 Series 9200/IQ8 Quad intelligent fire detectors or bus devices, subdivisible into 127 detection zones


Loop Card Esserbus/Esserbus-PLus Modules are used for FlexES Control. Modules are provided with plastic protective housing for connection of an Esserbus/Esserbus-PLus loop. Mixed operation of Esserbus and Esserbus-PLus is possible in a fire alarm panel. Up to 18 loops can be realized depending on the extension of the alarm panel and on the number of available module slots. Up to four modules without galvanic isolation can be used in the fire alarm panel. If more than 4 loop modules are used in a panel, modules with galvanic isolation (GI) are necessary to be used from the fifth loop module onwards. Mixed operation of the modules with/without galvanic separation within one control panel is easily possible. Modules are locked mechanically without screws in the slots, just quick & easy. HOT PLUGGING and automatic recognition of modules just by Plug & Play, makes start-up and maintenance easy to handle.
