Network Technology


The essernet is a short circuit and open circuit resistant 2-wire backbone for networking fire detection and intrusion detection panels from Esser''s product range. The essernet permits both hierarchy-restricted and hierarchy-free programming of panels. The essernet has been tested and approved by the VdS. The hardware components are listed in the respective equipment approvals of the fire detection panels.

Up to 31 panels can be networked with each other in a ring loop. Superior functions and functions covering different panels can be programmed. The status of the entire system can be read off on anything from one to all panels as desired. Likewise, the system can be operated entirely from one panel.

Networking can be carried out via a simple telecommunication cable, e.g. IY-ST-Y 2 x 0.8mm, with 784840 or using a data cable, e.g. IBM type 1 as well as CAT5 cable, with 784841. With the essernet repeaters, cable distances of up to 3000m between two panels are possible. An optical waveguide fibre is possible with the converters, which are listed below.

Third-party or management systems (e.g. WINMAG) can be connected via the serial essernet interface.
