Service available at all US ports — 24/7 worldwide. Our next available technician contacts you within 1 hour.
Symptom checklist
What we hear from the bridge.
- ›Ionisation detector test card shows >20% sensitivity drift
- ›Beam detector loses signal after the vessel rolls heavily
- ›Aspirating sampling line clogged with cargo dust
- ›False alarms only when galley fan is running
Likely root causes
Where the fault usually lives.
- ›Detector head dust loading beyond chamber threshold
- ›Beam path misalignment after hot work nearby
- ›Sampling pipe pin-hole blockage
- ›Pressure differential through the protected space changed

FAQ
Common questions for this system.
- Which smoke-detection technologies and brands do you service?
- Consilium Salwico, Autronica BS-100, Thorn Marine and Notifier addressable loops with ionisation, optical (photoelectric) and beam detectors, plus Wagner Titanus and VESDA-E aspirating systems on cargo and machinery spaces. We test sensitivity drift with the manufacturer's hand-held service tool (e.g. Consilium SMT-2), clear sampling-line blockages with reverse air-purge, and verify zone addressing on the loop with a Fluke 87V and the panel's diagnostic menu.
- How long does a full smoke-detection system test take?
- On a mid-size bulker with 120-160 addressable detectors, a full point-to-point test using smoke aerosol and the panel log takes eight to ten hours over a watch. Aspirating system sensitivity verification with calibrated smoke and flow-test of each sampling pipe adds two to four hours. We disable cross-trips to general alarm and CO2 release at the panel during testing with the Chief Officer's sign-off and restore them with a witnessed end-to-end test before leaving.
- Is the smoke-detection report acceptable to class and flag?
- Yes. The report references SOLAS Ch II-2 Reg. 7 and FSS Code Ch 9, lists each addressable point with detector type, sensitivity reading, pass/fail and date of last replacement, and is in the format DNV, BV, ABS, Lloyd's Register, ClassNK, RINA, TL and IRS surveyors expect for the annual / renewal Safety Construction survey item. Service tool calibration certificate and aspirating flow-test print are annexed.
