Section 6 - MAINTENANCE AND
CLEANING
Maintenance:
The EVC-PY-IS detector is a high quality product engineered for reliability. In
order to obtain optimum performance, periodic maintenance is required. If
proper preventative maintenance is not carried out, there is a likelihood of
malfunction, as a dirty detector is more likely to cause a false alarm.
Servicing:
Servicing of the system should be carried out in accordance with the
requirements of BS 5839 Part 1, Fire Detection and Alarm Systems
for Buildings: Code of Practice for System Design, Installation
and Servicing.
The maintenance procedures described below should be conducted with the
following frequency:
One month after installation:
Routine Inspection and every 3
months
after.
Every 6 months:
Operational Test.
Every 12 months:
Functional Test and Clean.
All above frequencies of maintenance are dependent on
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 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 to
ensure 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.
