Operational Test
The purpose of the Operational Test is to confirm the sensor’s correct
operation in response to a smoke 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.
ii)
Introduce a naked flame into the range of the sensor by using a
lit match or cigarette lighter held 1-10m in front of the
detector. Check that the detector gives an alarm condition
within 15 seconds. Check the LED indicator on the
EV-UV
sensor illuminates and any remote indicator LED fitted
also illuminates.
iii)After the sensor has given the alarm condition, reset the sensor
from the control panel. It may be necessary to allow a short
time to elapse before resetting the detector.
Functional Tests:
The functional test checks the detector's operation. These detectors
may be returned to our factory 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. Be careful not to wipe
abrasive particles, e.g. dust and grit, across the quartz glass
window of the detector when cleaning.
iii)
If the unit needs further cleaning, or is damaged or corroded,
please return the complete sensor to Nittan (UK) Ltd. for service.
