The terminal makes a buzz.
Depending on the type of the interphone connected to
NAC-3000M, there may be serious howling. If you use Kocom's
interphone (DP-202H) that has proven compatibility with
NAC-3000M, howling can be eliminated.
Is there any countermeasure against static electricity?
NAC-3000M obtained CE certification with regard to ESD
(Electro Static Discharge), and passed the internal QA
certification test. So we guarantee that this device satisfies
Level 3 (Contact: 6kV, Air: 8kV) of the IEC 61000-4-2 standard.
However, if it is installed in wintertime or in a place with low
humidity and carpeted floor, 35kV of static electricity can be
discharged to people. So please exercise caution when using
the device in such an environment.
What can I do if the device is destroyed by an intruder?
Depending on installation methods, NAC-300 can be
categorized into the general type and the buried type. As the
buried type is kept inside the wall, it is safe from accidental
damage. The general type is protected with a metal bracket
and cannot be damaged easily. However, in case someone
tries to destroy or disassemble it by force, the tamper switch
works with alarm sound.
