Features
- RS 485 interface on board for a max. length of 1,000 m
The serial essernet interface is a router with internal RS 485 interface for interfacing an 8000 fire alarm panel over relatively large distances e.g. subnetworks.
Information from the connected fire alarm panel is received via a router/router link and made available in the host essernet. The first SEI is connected as Master and the second SEI as Slave.
It has a slot for an essernet loop module and is thus an integral device in the short circuit and open circuit resistant essernet. For remote function, you can use the integrated RS 485 interface.

784840.10 essernet micromodule (62.5 kBd)
784841.10 essernet micromodule (500 kBd)
The essernet micromodule and the interface module either RS 232 (Part No. 772386) or TTY (Part No. 772387) are not included and must be ordered separately in accordance with the required essernet type and the serial transmission standard. The optional interface module must be ordered separately and is a supplement to the serial essernet interface. It is plugged into the connectors provided on the main PCB. Depending on the required application, a TTY /CL 20 mA (Part No. 772387) or a RS232 / V.24 (Part No. 772386) interface module may be installed on the serial essernet interface.
