FSL100 Series Flame Detectors
Technical Handbook
6.2 Functional Testing
The FSL100 flame detector has been tested in the factory and shall be tested as part of installation and commissioning. In
addition the flame detector should be functionally tested regularly (i.e. weekly) as part of a site fire alarm test. Check and clean
the FSL100 window prior to testing. Contamination lowers the sensitivity of the flame detector and can build up over time if not
monitored and cleaned regularly.
Honeywell supplies the FSL100-TL (safe area) and FSL100-TLX (hazardous area) test lamps for the FSL100 series of flame
detectors. Please read the test lamp instructions in this manual before you start the functional test.
6.3 Fault Analysis
False alarms may be triggered by transient events or because:
1. The sensor is activated by a known or unknown source in its field of view.
2. The sensor is activated by electromagnetic interference.
3.
The sensor is activated by cabling faults or damage (may be intermittent).
4.
The sensor electronics are faulty.
A single false alarm should not cause undue concern, but a series of false alarms should be carefully investigated to rule out the
causes listed above. You should also consider other factors such as season, weather, time of day, ambient temperature or
humidity, angle of the sun, etc.
Warning
A user-defined performance requirement may stipulate that an actual (real) fire performance test is carried out
from time-to-time. Ensure that a Safe System of Work is used to avoid the risk of death, injury or damage to
property.
Caution
Always ensure that relay operated outputs and alarms are inhibited or isolated before carrying out any work on
Alarm systems.
Always ensure that Alarm Systems are returned to Normal Operation when work is completed.
