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. Testing 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.).
