Installation and Operations Manual V1.4 Ramtech Electronics Limited 2018
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 sensor head is secure and undamaged.
ii) Check the smoke entry apertures are in no way obstructed.
iii) Ensure the surface of the sensor’s outer cover is clean. If
there are deposits due to the presence of oil vapour, dust
etc, then the sensor should be cleaned in accordance with
the cleaning instructions detailed later in this manual. It
may be advisable to ensure that such cleaning is conducted
regularly in the future.
iv) Ensure no equipment which may generate combustion
products or ne airborne particles, has been installed in the
vicinity of the sensor since the last routine inspection.
If such equipment has been installed, then you should notify
the Fire Safety Ofcer or other competent authority that its
presence may cause false alarms.
Operational Test
The purpose of the Operational Test is to conrm the sensor’s correct
operation in response to a heat condition.
i) Testing the sensors 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 sensor
head, e.g. using a ‘No Climb -Solo’ smoke test head.
Check that the sensor gives an alarm condition within 15
seconds. Check the LED indicator on the Sensor
illuminates and any remote indicator LED tted also
illuminates.
iii) Before proceeding to the next sensor, ensure that the
sensor just tested does not re-operate due to the presence
of residual smoke.
Functional Test
The Functional Test checks the sensor’s operation. These sensors may
be returned to WES Customer Support for Functional Testing.
Cleaning
Note : The sensor head should NOT be disassembled.
i) Carefully remove the sensor 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 sensor to Ramtech
Electronics for service.
