There are 3 areas where the Portascanner® 520 will assist you in your Room Integrity Tests /
Door Fan Test (DFT):
Based on the assumption that many rooms fail their initial Room Integrity Test, the handheld
Portascanner® 520 will assist in:
indicate location and extent of leak sites prior to a scheduled DFT session for
remedial action to be taken to maximise the “PASS” rate the test.
contractor’s range of services by finding and patching up leaks before the
scheduled DFT test day. This is because sealants take time to set and may impede
the operations of a DFT if remedial work is conducted on the DFT scheduled day
ultrasound is fast and non-invasive, a quick ultrasonic leak survey can be conducted
on site to locate early leak sites. This information can assist the fire contractor’s
quoting process and may act as preliminary evidence to justify the quote proposed.
Overall, this practice improves the prospect of securing an initial DFT “PASS” – and
thus delivering up an efficacious fire protection outcome.
the exact location and extent of the leak sites while the DFT is being carried out.
alongside DFT allows remedial work to be conducted immediately.
Based on the assumption that the structural integrity of rooms will change over time, the
handheld Portascanner® 520 will assist in:
achieve the retention time required, periodic ultrasonic room integrity tests can be conducted
using an ultrasound scanner to comply with enclosure integrity maintenance as
listed in the ISO 14520, EN15004 and NFPA regulations.
room can remain continuing their daily tasks without affecting the leak detection
