Simple placement and maintenance considerations for residences.
What to review
- Use manufacturer instructions for placement and testing.
- Prioritize sleeping-area approaches and circulation routes.
- Test alarms regularly and replace batteries or units as specified.
- An alarm supports early warning but does not replace escape planning.
When to stop and call a professional
Stop using equipment or a circuit when there is heat damage, smoke, burning odour, sparking, repeated protective-device operation or electric shock sensation. Do not open energized equipment unless you are qualified and authorized to do so.
Emergency: If there is active fire, smoke, gas leakage or immediate danger, leave the area, warn others and contact the local emergency service. A website checklist is not an emergency response service.
