C. For the smoke detector testing (Go / No-Go)
1.
To test the optical detector, introduce a certain amount of aerosol into the detector
’s
head, using HSI FIRE &
SAFETY Aerosol canned smoke testers
“25S” or “30S”
.
Please follow the manufacturer’s recommendations
on their use.
2.
Check that the detector gives an alarm condition within 15 seconds. Check the red LED indicator is on and
the green LED is flashing on the
EVA-PYH
combination detector. If the red LED fails to light, check the power
to the detector and the wiring in the detector base.
3.
After the detector has given the alarm condition, the detector automatically is reset by the control panel. It
may be necessary to allow a short time to elapse before resetting the detectors, to allow any residual aerosol
from the test to disperse.
4.
Detectors that fail these tests should be cleaned as described under MAINTENANCE Section and retested. If
the detectors still fail these tests they should be returned for repair.
5.
Before proceeding to the next detector, ensure that the detector previously tested does not re-operate due to
the presence of residual aerosol.
D. For the smoke detector sensitivity
1.
Detector sensitivity can be tested using Smoke Detector Sensitivity Analyzer Model 501-B (Gemini Scientific
Corp.).
Please follow the manufacturer’s recommendati
ons on their use.
Where the sensitivity limits for the Analyzer are 0.6 %/ft. ~ 1.3 %/ft.
2.
Check that the detector gives an alarm condition within 40 seconds after the aerosol of which the
concentration controlled with the Analyzer was introduced
into the detector’s head.
Check the red LED
indicator is on and the green LED is flashing on the
EVA-PYH
combination detector. If the red LED indicator
fails to light, check the power to the detector and the wiring in the detector base.
3.
After the detector has given the alarm condition, the detector automatically is reset by the control panel. It
may be necessary to allow a short time to elapse before resetting the detectors, to allow any residual aerosol
from the test to disperse.
4.
If the detector has a hist
ory of nuisance alarm, check that the detector doesn’t give an alarm condition within
50 seconds when the aerosol less than low sensitivity limit was introduced into the detector’s head.
5.
Detectors that fail these tests should be cleaned as described under MAINTENANCE Section and retested. If
the detectors still fail these tests they should be returned for repair.
6.
Before proceeding to the next detector, ensure that the detector previously tested does not re-operate due to
the presence of residual aerosol.
