Manual O I Test Initiated By Enhanced Flame Inspector - Det-Tronics X Series Instructions Manual

At the detector:
Fault Relay becomes de-energized.
LED turns amber.
6. Remove the magnet or release the test switch. The
Manual o i Active indicator turns off, and the Manual
o i Fault indicator remains on.
7. The fault indication can be reset by momentarily
applying the magnet or manual o i switch.
8. Clean the detector viewing windows following the
cleaning procedure described in the "Maintenance"
section of the detector instruction manual.

MANUAL TEST INITIATED BY
ENHANCED FLAME INSPECTOR
1. Click on the Control tab. The Control window is
displayed (see Figures 10 and 11).
2. Two options are available for the manual o i test:
Clicking Start Active Manual o i will activate
–
the Fire Alarm Relay and generate a 20 mA
output as part of a successful test.
– Clicking Start Passive Manual o i does not
activate the relay or the 4-20 mA output. A
successful test is indicated by the detector
LED in the Status window. Except for the Fire
Relay and 4-20 mA output, all other aspects
of the test are identical.
If the detector is fully operational (the sensor
module is not removed from the detector housing),
an active manual o i test requires disabling of all
e xtinguishing devices to avoid release resulting
from a successful test.
Click on the appropriate button to initiate the test. If
Start Active Manual o i was selected, a dialog box
appears asking if you want to start a Manual o i test. If all
extinguishing devices are disabled, click Yes to initiate
the test. If Start Passive Manual o i was selected, the test
begins immediately.
3. Click on the Status button to display the Status
window. (Progress and results of the Manual o i test
cannot be monitored from the Control window).
4. The Manual o i Active indicator turns on (red). If the
test is successful:
3.1
CAUTION
At the PC:
Fire Alarm indicator turns on (red).
The 4-20 mA indicator reads 20 mA.
At the detector:
Fire Alarm Relay changes state.
The 4-20 mA output goes to 20 mA.
LED turns red.
5. The Inspector program automatically turns off the Fire
Alarm and Manual o i Active indicators, turns on the
Normal indicator (green), resets the Fire Alarm relay
and LED, and sets the 4-20 mA output to 4 mA.
If the detector has successfully completed the test, any
fire extinguishing devices that were disabled for the test
can be returned to normal operation.
6. If the detector fails the test (i.e. less than half of the
detection range remains), no fire alarm is produced
and a fault is generated. A failed manual o i test is
indicated by:
At the PC:
Manual o i Active indicator turns off.
Manual o i Fault indicator turns on (amber).
At the detector:
No change to the Alarm Relay.
4-20 mA output indicates a fault condition.
The Fault Relay becomes de-energized.
The LED turns amber.
7. The fault indication can be reset by momentarily
applying the magnet or manual o i switch.
8. Clean the detector viewing windows following the
cleaning procedure described in the "Maintenance"
section of the detector instruction manual.
