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 1 A / 1000 V diode (e.g.,
1N4007, 1N5407, 1N5408) connected antiparallel to the device.
