Installation and Operations Manual V2.0 Ramtech Electronics Limited 2020
The maintenance procedures described below should be conducted
with the following frequency:
One month after installation
: Routine inspection
Inspection every 3 months thereafter
Every 6 months
: Operational Test
Every 12 months
: Cleaning
All above frequencies of maintenance are dependent upon ambient
conditions. Best judgment should be used to ensure proper
maintenance.
Routine Inspection
i)
Ensure the detector head is secure and undamaged
ii)
Check the heat entry apertures are in no way obstructed.
iii)
Ensure the surface of the detector’s outer cover is clean. If
there are deposits due to the presence of oil vapour, dust
etc, the detector should be cleaned in accordance with the
cleaning instructions detailed later. It may be advisable
that such cleaning is conducted regularly in the future.
iv)
Ensure 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, 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)
Testing the detectors will trigger the site wide alarm. To
avoid unnecessary evacuation site personnel should be
informed when testing starts and when testing is complete.
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.
Note: 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, silence
the system from a fire point or base station. It may be n
necessary to allow a 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 detector’s operation. These detectors
may be returned to WES Customer Support for Functional Testing.
Cleaning
Note: The detector head should NOT be disassembled.
i)
Carefully remove the detector head from its base.
ii)
Use a soft, lint-free cloth, moistened with alcohol for sticky
deposits, to clean the plastic casing.
iii)
Using a soft bristle brush (e.g. an artist’s paint-brush)
carefully brush between the vanes and thermistor in a linear
motion away from the apertures on the plastic case.
iv)
Ensure that no debris is left on or around the thermistor
once cleaning is complete.
v)
If the unit needs further cleaning, or is damaged or
corroded, please return the complete detector to
WES Customer Support for service.
