Smoke alarm installation guide

Where do I install them?

In addition to the minimum requirement of one smoke alarm per level, Fire and Rescue NSW research recommends installing smoke alarms in all bedrooms and living spaces (including hallways and stairways) and even the garage.

Avoid fitting smoke alarms in or near your kitchen or bathroom.

The ideal position is on the ceiling between sleeping and living areas.

Use the plans below as a guide.

How do I install them?
