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
: Routine inspection
installation and every 3
months thereafter
Every 6 months
: Operational Test
Every 12 months
: Cleaning
All above frequencies of maintenance are dependent upon ambient
conditions.
Routine Inspection
i)
Ensure the detector head is secure and undamaged.
ii)
Check the smoke 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, then the detector should be cleaned in accordance with
the cleaning instructions detailed later in this manual. It
may be advisable that such cleaning is conducted
regularly in the future.
iv)
Ensure no equipment which may generate combustion
products or fine airborne particles, 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 Fire 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)
Introduce a discreet amount of smoke into the detector
head, e.g. using a ‘No Climb -Solo’ smoke test head.
Check that the detector gives an alarm condition within 15
seconds. Check the LED indicator on the Detector
illuminates and any remote indicator LED fitted also
illuminates.
iii)
Before proceeding to the next detector, ensure that the
detector just tested does not re-operate due to the presence
of residual smoke.
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) care
fully brush between the vanes in a linear motion away from
the smoke entry apertures.
iv)
It is permissible to blow dust from the chamber, without
removing the cover, using a clean air line.
v)
If the unit needs further cleaning, or is damaged or
corroded, please return the complete detector to Ramtech
Electronics for service.
