Extension module of four readers and four doors to connect in network Rs485 to OMNIA-IP-PLUS controllers.
This module can control 4 doors in one way (using 4 entrance readers and 4 exit buttons) or 2 doors in double way (using 2 entrance readers and 2 exit buttons). Every door module also includes a conditional input like for example a magnetic detector for vehicles. Every module also has got an independent input for exit button and another one for door contact to detect if the door remains open after a period of time. The output relay has got two contacts: open and closed. The module has got itself a tamper input contact and another input for the detection of network tension problems.
The connection to the controller bus is done through a terminal block or a RJ45 connector, being the bus in Rs485 protocol, which allows distances up to 1000 meters.
The module is available in two versions: One 12V version with little box (V-EXT-4) and another 230V.AC inside a metal box and incorporating the power supply and a place to put the optional batteries (V-EXT-4-230).
