Untested Smoke Alarms
Smoke alarms are sighted but their operational status cannot be confirmed during a standard visual inspection, which does not include functional testing of alarm devices. Western Australian legislation under the Residential Tenancies Act and the Building Act requires interconnected, photoelectric alarms in defined locations; whether the installed units meet that standard remains unverified until tested by a licensed electrician.
Severity rationale
Across 743 observations, the modal score is 3, recorded in 484 cases (65.1%). Scores of 4 account for 206 findings (27.7%) and scores of 5 for 36 (4.8%), meaning roughly one-in-three findings sits at the higher end of the range. The average of 3.35 reflects an unresolved compliance risk rather than confirmed failure - severity rises when the inspection cannot confirm any alarm functionality, when the unit type is visibly non-compliant, or when the property is a pre-purchase transfer where vendor certification obligations apply. No observations fell at score 1; the floor of 2 reflects that a physically present alarm, even untested, still offers some deterrence.
Causes
- No recent test or certification record available at the time of inspection
- Functional testing of alarm devices falls outside the AS 4349.1 visual inspection scope
- Potential non-compliance with WA smoke alarm legislation (type, location, or interconnection)
- Alarm age or battery condition unknown, raising doubt about reliable activation
- Lack of any visible compliance label, service tag, or installation date on the unit
Symptoms to look for
- Smoke alarm unit sighted but operational status unconfirmed - inspector could not test activation
- No service record, compliance sticker, or installation date visible on the alarm
- Unit may be ionisation-type, battery-only, or incorrectly located - compliance cannot be confirmed visually
- Alarm condition (yellowed casing, damaged cover, corroded contacts) suggests age or neglect
Remedies
- Engage a licensed electrician to test each alarm, confirm type (photoelectric required in WA), and certify compliance before settlement
- Replace any ionisation-type or battery-only alarms with hardwired, interconnected photoelectric units to meet current WA requirements
- Confirm alarm locations against AS 3786 and WA Building Regulations - bedrooms, hallways, and living areas all carry specific placement rules
- Check with the settlement agent regarding vendor obligations under WA legislation to certify smoke alarms prior to sale
- Schedule annual alarm testing and battery replacement as part of ongoing property maintenance

Worth asking our inspector about this specifically.
Arrange electrician testing and certification before settlement if this is a purchase - WA legislation places the obligation on the vendor and the window is tight. For existing owners, test alarms now and book an electrician if any unit fails or cannot be confirmed as photoelectric and interconnected.
