Common failures & inspection points
Visual inspection of detector lens and internal optical elements for dust, insect debris, corrosion, or condensation; perform monthly visual check and semi-annual smoke-entry functional test per NFPA 72
Sensitivity testing of detector elements within 1 year after installation and every 2 years thereafter; for aspirating systems, verify suction pressure (>400 Pa) and air sample integrity
Visual inspection for cracks, corrosion, impact damage; verify mounting security and alignment; check for loose connectors or cable damage; test mechanical self-testing indicators (for YMX5000 cyclic optics monitoring)
Functional test of detector signal transmission to control panel; verify alarm and fault relay operations; test communication loop continuity; check battery status (for battery-powered units like Ei series), expected 10-year life
Document installation date; replace heat detectors (WMX series) after 15 years maximum service life; replace aspirating smoke detectors (AMX series) per manufacturer recommendations typically 20-25 years; check for obsolescence of electronic components
