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.
Warning

4
Phone line. The phone line could be out of order or busy for a
while. An intruder may also attempt to sabotage it by means of
sophisticated methods. This practice is very difficult to detect.
Insufficient time. In some circumstances, even if the device is
working properly, it is possible that response measures are not
taken in time to protect the occupants or their belongings.
Malfunction of a component. Despite utmost efforts to produce
the most reliable system possible, it could fail on the grounds of
the malfunction of a component.
Inadequate inspections. Most of the problems which cause
malfunctions in a system can be detected by performing regular
checks and maintenance. The whole system should be tested on
a weekly basis and immediately after any intrusion or intrusion
attempt, fire, storm, earthquake, accident or any kind of building
works.
Security and insurance. Despite all its advantages, an alarm
system is not a substitute for home or life insurance. An alarm
system does not exempt the user from taking precautions
regarding prevention and minimisation of damages in an
emergency situation.

The Check the following table in order to calculate the number of detectors
that should be installed in a room. The maximum area of coverage by a fire
detector (Sv) depends on the height of the room and the degree of ceiling
slope.

Where should I install a NEXHO-IC fire detector?

6
Unscrew by turning the head anticlockwise with respect to the detector
base. Push the snap onto the 9-volt battery. Place the battery inside the
battery holder.
Place the detector on the ceiling and mark the fixing screws’ location using
a pencil.
Remove the detector head momentarily and insert the wall plugs in the
marked locations. Partially insert the screws into the wall plugs using a
screwdriver. Hold the detector head up to the ceiling again and insert the
screws into the holes previously used as a marker. Turn the detector head
until the screws are located over the narrowest part. Drive the screws in to
fix the head to the ceiling.
INSTALLATION AND SETUP
Installation running on batteries

7
To close the NEXHO-IC fire detector, align the arrow that is engraved on
the detector head next to the pilot light with the mark engraved on the side
of the base. Turn the head clockwise until the arrow lines up with the two
marks engraved on the base.
The fire detector NEXHO-IC will emit an audible warning signal upon
detection of a fire in the room where it has been placed.
Please note that the fire detector must be configured
together with the NEXHO-NT internet control module or the
NEXHO-UC central control unit so that the detector is
installed in the system and can be controlled from one of
these control units. For that purpose, consult the section on
how to install fire detectors in your automation network in the
user manual of the NEXHO-NT internet module or the
NEXHO-UC central unit.
Once the device has been configured in the home-automation
system, it is advisable to install an audible warning alarm for
interior spaces connected to a NEXHO-CR power-control
module. Please consult the user manual of either the NEXHO-
NT internet module or the central control unit to learn how to
configure the security mode so that it activates the audible
warning alarm in case of detection.

8
The NEXHO-IC fire detector can be powered by an external 12-volt power
supply.
For that purpose, unscrew by turning the head anticlockwise with respect to
the detector base.
Place the detector base on the ceiling. Guide the external power supply
cables through the hole of the device designed for this purpose and mark
the location of the fixing screw holes using a pencil.
Remove the detector head momentarily and insert the wall plugs in the
marked locations. Partially insert the screws into the wall plugs using a
screwdriver. Hold the detector head up to the ceiling again and insert the
screws into the holes previously used as a marker. Turn the detector head
until the screws are located over the narrowest part. Drive the screws in to
fix the head to the ceiling.
Cut the wires of the 9-volt battery close to the snap. Respecting the
polarity, join the two terminals of the power supply with the two wires that
were previously connected to the snap.
To close the NEXHO-IC fire detector, align the arrow that is engraved on
the detector head next to the pilot light with the mark engraved on the side
of the base. Turn the head clockwise until the arrow lines up with the two
marks engraved on the base.
The fire detector NEXHO-IC will emit an audible warning signal upon
detection of a fire in the room where it has been placed.

The NEXHO-IC fire detector allows you to perform a magnetic test to check
the proper functioning of the device.
In order to perform a test, hold a magnet to the pilot light of the device
head. At this point, all device warning light indicators should light up. After
a few seconds, the alarm will emit an audible warning signal.
If this does not happen and the device is running on battery power, replace
the battery and perform a new test.

How do I reset a NEXHO-IC fire detector?
If you have installed the NEXHO-IC fire detector in a NEXHO
home-automation installation, once it has been reset, the
detector will not send warning alerts for possible detections
until you have re-configured it. To re-configure it, please refer
to the manual of the NEXHO-NT internet module or of the
NEXHO-UC central control unit and follow the steps described
in the section on how to install the corresponding detector in
the home-automation network.
