Smoke alarm installation guide

Where do I install them?

In addition to the minimum requirement of one smoke alarm per level, Fire & Rescue NSW recommends installing smoke alarms in all rooms where people sleep and the hallways leading to sleeping areas.

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.

Single floor plan

  Smoke alarms for minimum legal requirement.

Multi-level floor plan

How do I install them?

Hard-wired smoke alarms need to be installed by a licenced electrician.

Always install smoke alarms in accordance with manufacturer’s instructions.

If it is difficult for you to fit one yourself, contact your local Fire & Rescue NSW station for advice.
