Loop card bus/bus-PLus Module

The Esser Loop card esserbus/esserbus-PLus Module for FlexES control module in a 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/or 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.

• For a maximum of 127 devices (IQ8Quad intelligent fire detectors, MCP’s, detector Series 9200, esserbus transponder or loop-powered signalling devices)
• Loop length up to 3.5km
