This system has been carefully designed to be as effective as possible.
There are some occasions, however, on which it cannot provide accurate
detection. The operation of any kind of alarm system can be intentionally
impeded or fail for other reasons, such as the following:
 Improper installation. A security system must be properly
installed to provide appropriate protection. This device should
not be placed in locations where it could be exposed to humidity
or liquid from water sprinklers. Each installation must be
evaluated to ensure that all areas are covered.

It is very important that the security system is serviced
periodically to ensure that it is in proper working order and
parts must be updated or replaced if they are not providing the
expected protection.

Power cuts. NEXHO-IC requires an appropriate energy supply for
proper operation. If the device is working on batteries, it is
possible that they will fail. Even if the batteries do not fail,
please make sure that they are in good condition and are
installed properly. If the device is running on an external power
supply, any outage, even of short duration, will interrupt the
operation during the power cut. Power cuts of any duration are
often accompanied by voltage fluctuations which can damage the
device. Following a power outage, please perform a complete
check of the system to ensure that it is working properly.
 Discharged batteries. The lifetime of a battery depends on the
environment in which it is found and on the number of
activations of the device. Environmental conditions such as
excessive humidity, high or low temperatures or abrupt
temperature changes can reduce the lifetime of the battery.
Regular inspections and maintenance will keep the system in
good operational condition.

Sound alarm devices may not be heard by hearing-impaired
people.
