4.7 Filters
Figure 4-3: Filter
The sampled air is passed through a filter (order code: FL53) before entering the detector chamber.
Figure 4-4: Xtralis Inline Filter
Additional filtration of sampled air may be required in harsh environments. Refer to the Xtralis Inline Filter
Application Note (17785) for further information.
4.8 Standard Pipe Configuration
Figure 4-5: Standard pipe configuration
The double pipe configuration can have a maximum length of 200 m (100 m per branch) with up to 18 sampling
holes per branch. Pipes should be balanced with equal lengths and equal number of holes.
All configurations with maximum pipe length or number of sample holes should have the Alarm (Fire) threshold
set to Level 1 and Fan Speed set to 9. The use of additional bends as described in Section 4.3 will have
minimal effect on performance (e.g. response time).
Note: Stated limits are based on EN54-20 certification testing. Reductions in pipe length may allow the
fan speed to be reduced and/or number of holes or alarm threshold level increased. Results of such
changes, or non-standard or unbalanced configurations, should be verified by using ASPIRE pipe
design software. Refer to Chapter 9 for details on EN54-20 class sensitivities.
