What is NX-4 intended for?
NX-4 is a personal safety alarm system primarily intended for use in mobile homes where health and
life can be endangered if you are attacked with narcosis gas by robbers, gas leakage from cooking
apparatus, fire or unknown persons (which may be robbers) close to the vehicle*. All the built in
functions in the NX-4 will provide an added insurance against these hazards. You might look at NX-4
as an “electronic night watch”.
NX-4 operates at 12 or 24V and is well suited for mobile homes, trucks and caravans.
*Motion detectors are optional.
