Manual: EV-DPH Manual 000027 (Changes are subject to DCRN)
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 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
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 sensor’s
correct operation in response to a smoke/heat condition.
Note: When carrying out site testing of Analogue Addressable
Evolution detectors, the CIE shall be set to test mode prior to
beginning the tests.
i)
Take any necessary precautions at the control panel to limit the
sounding of the alarm sounders/bells and any fire service
summoning device.
