DIVUS OPENDOOR manual 71
4 OD-Secure
4.1 INTRODUCTION
The OD-Secure avoids external hacking of the local network through the network connection of the OPENDOOR
door station. A micro sabotage switch checks if the housing of the OPENDOOR door station is closed or opened.
If this sabotage switch detects, that the housing was opened, OD-Secure cuts the OPENDOOR door station physi-
cally from the network. Once the sabotage switch has caused OD-Secure to cut the network connection, also by
pressing the sabotage switch manually the network connection will not be reconnected. Only by pressing the
reset button on the OD-Secure it will restore the network connection.
But the OD-Secure does not only cut and restore the network connection, it has a 24V DC output, which is disa-
bled on a sabotage detection and enabled by pressing the reset button. So it’s possible to power down the whole
door station on a sabotage detection. This can be used to prevent manipulation of the electrical door opener. If
the switched 24V DC is used to actuate the electrical door opener, once the OD-Secure has detected a sabotage
and switched off the 24V DC power supply output it’s not possible any more to actuate the electrical door opener
on the OPENDOOR door station by bridging the screws of the relay connected to the door opener; just because
the OPENDOOR door station is no more power supplied and the door opener, too.
The power supply will be re-stored by pressing the reset button on the OD-Secure.
