1. Introduction
1.1 How the detector works
The heat detector detects rises in temperature that trigger an
alarm in the following cases:
• when the room temperature rises at an abnormal speed,
or
• when the room temperature reaches between 54°C and
70°C,
(also refer to the table in the Technical Data section).
The heat detector is especially suitable for detecting fires that
spread quickly or at an average speed and in places where an
optical smoke detector cannot be used:
• in a kitchen where there are cooking fumes,
• in uninhabited places where there is a smoky atmosphere or
a lot of dust (e.g. garages).
The heat detector can be:
• used as a stand-alone unit,
• integrated into a Daitem alarm system,
• interconnected in a hard-wired network of up to 40
detectors (heat or smoke).
IMPORTANT: the heat detector is not supposed to replace
smoke or gas detectors to ensure the safety of people
against smoke or gas, and notably in rooms such as
bedrooms, playrooms and other living areas.
IMPORTANT: the heat detector is designed to protect
homes or the private areas of buildings. It is not designed
for public assembly buildings or buildings housing workers.

4.1 Choosing the best place
The detector must be placed:
• in rooms where there is a risk of fires
spreading quickly or at an average speed,
• in rooms with an aggressive or difficult
environment such as kitchens (cooking
fumes), garages (smoky atmosphere), and
other unoccupied premises or rooms where
there is often a lot of dust,
• preferably at the centre of the ceiling but
positioned so that it is affected by any
abnormal rises in temperature,
• if the detector cannot be installed in the
centre of the ceiling, install it more than 50
cm away from the corners of the room (Fig.
1 and Fig. 2),
• far away from ventilation grilles that may
spread the heat,
• more than 50 cm away from obstacles
(walls, partitions, beams, etc.),
• at either end of corridors more than 8 m
long,
• far away from potential sources of electrical
interference (electricity meter, metal cabinet,
etc.),
• if it is to be installed on a metal wall, insert a
shim made of non-magnetic material (wood
or plastic).
The detector must not be placed:
• in rooms where a sudden and considerable
rise in the room temperature would cause
untimely triggering of the alarms (e.g.
sudden sunlight),
• in rooms where there is a need to protect
people against smoke or gas(bedrooms,
children’s playrooms, converted cellars,
occupied lofts, emergency exits, etc.),
• near fluorescent tubes,
• directly on a metal surface,
• in a room where the temperature could drop
below -10°C or rise above +55°C, as this
will prevent the detector from operating
properly,
4. Installing the detector
Make sure there is a distance of at least 2 m between each product, except between two
detectors.
IMPORTANT: the heat detector is not supposed to replace smoke or gas detectors to
ensure the safety of people against smoke or gas, and notably in rooms such as bedrooms,
playrooms and other living areas. The heat detector is designed to detect fires in places
where an optical smoke detector cannot be used. For basic protection, a smoke detector
should be installed in at least each bedroom (refer to smoke detector manual).

GB
4.2 Testing the radio range
at the chosen location
1. old down the detector programming key
0 or the test button until the built-in
sounding can be heard:
• correct: the control panel confirms the
radio link with a voice message “beep,
fire detector n° X”,
• incorrect: if there is no voice message,
move the heat detector closer to the
control panel.le.
2. Put the control panel back in user mode by
pressing:
• in rooms where the relative humidity might
rise above 95% (without condensation),
• close to heating, cooling or air vents.

IMPORTANT: 155-21X heat detectors can only be connected with the same type of
detectors: e.g. a 155-21X can be connected with 155-21X heat detectors or 151-21X smoke
detectors.
For 15 mm2wires, the overall network length must not exceed 400 m.
3. Clip the connector block back in place.
4. Lock the detector onto the base (see Fixing the detector in place).
You can therefore be sure of being warned if smoke is detected in a room far away from the
room in which you are in.

Although alarm sounding is reduced during a
manual test of a heat detector, it is advisable
to inform neighbours beforehand and to use
all suitable hearing protection devices.
Testing the detector using the test button:
When you press on the “TEST” key for
10 sec., the detector performs an automatic
functional self-test. Among other things, it
examines the state of the heat sensor located
behind the detection head slots and thus
detects any defects linked to temperature
measurement. If the heat sensor is faulty, the
heat detector indicates that there is a
technical fault (see Indications section). There
is therefore no need to test the detector using
a source of heat.
5. esting the detector
IMPORTANT: you can recognise this heat
detector by the white slots in the detection
head. Unlike the smoke detector, the
smoke test spray (ref. TESTFUM) is not
suitable for testing heat detector operation.
IMPORTANT: so as not to cause a fire and
damage the mechanical parts and the
design of the device, never test it:
• using a naked flame,
• by moving it too close to a source of
burning heat (e.g. a paint stripper, hair
dryer, etc.).

To test the heat detector, press on the test button (for roughly 10 sec.) until the built-in
sounding is triggered. As long as the button is held down, the detector responds as follows:
As soon as the test button is pressed for more than 10 sec, and when connected to a
Daitem alarm system, the detector causes the following:
• triggering of the control panel and security system sirens in fire sounding mode for 5 minutes,
• triggering of the telephone dialler.
Stop the sirens and check that the control panel has memorised the alarm (see Indications
section).
IMPORTANT: these tests should be carried out at least
once a month and notably when you have been away for a
long time.

Manual disabling of the detector
It is possible to disable the detector for a 15 min period:
• prior to activities likely to generate abnormal heat (sudden rise in temperature or rise in room
temperature of above 54°C, e.g. during DIY work), and cause unwanted alarm activation,
• to stop the alarm when the heat generated is not dangerous (e.g. sudden sunshine), (only
possible with the detector having detected the rise in temperature and which can be
recognised owing to the flashing of its red LED).
In order to disable the detector, press the test button until the 1st beep sounds or until the
detector stops its built-in audible alarm. The LED indicating
the status of the detector flashes every 2 sec.
