can be connected to a standard local area network using a
LAN interface via the RJ-45 connector on the back panel. Always use CAT-5d or higher
class cables for reliability reasons.
Warning
Do not exceed the upper voltage and current limits to avoid irreversible
damage of the equipment.
Warning
When you connect a device containing a coil, such as a relay or an
electromagnetic lock, it is necessary to protect the intercom against voltage
peak while switching off the induction load. For this way of protection we
recommend a diode 1A / 1000V (e.g., 1N4007, 1N5407, 1N5408) connected
antiparallel to the device.
