iv) Ensure that no equipment which may generate
excessive heat has been installed in the vicinity of the
detector since the last routine inspection. If such
equipment has been installed, then you should notify
the Safety Officer or other competent authority that its
presence may cause false alarms.
Operational Test
The purpose of the Operational Test is to confirm the
detector’s correct operation in response to a heat condition.
i) Take any necessary precautions at the control panel to
limit the sounding of the alarm sounders/bells and any fire
service summoning device.
ii) Test the detector with heat from a warm air gun
designed for heat detector testing (e.g. ‘No Climb - Solo’
heat sensor tester). Check that the detector gives an
alarm condition within 10-20 seconds depending upon the
detector grade and the applied air temperature. Check
that the LED indicator on the detector illuminates.
N.B. Hot air blowers sold for paint stripping, soldering
pipes etc, generate sufficient heat to damage the detector
and should not be used for testing heat detectors.
iii) After the detector has given the alarm condition,
reset the detector from the control. It may be necessary
to allow some short time to elapse before resetting the
detector, to allow any residual heat from the test to disperse.
iv) Before proceeding to the next detector, ensure that
the detector just tested does not re-operate due to the
presence of residual heat.
Functional Test:
The Functional Test checks the detectors operation.
These detectors may be returned to our factory for
Functional Testing.
