Smoke Alarms That Are Properly Installed and Tested

Smoke alarms are life safety equipment, so placement, condition and testing matter.
We can check your existing alarms, replace expired or faulty units and install additional alarms where required or appropriate. Where the system supports it, alarms can also be interconnected so an activation in one area alerts occupants elsewhere in the property.

We keep the process simple, explain what we find and make sure the alarms are tested before we leave.

What We Can Help With Smoke Alarm Installation

New alarms positioned to suit the property and applicable requirements.
  • Replacement and Upgrades
Replace ageing, damaged or unsuitable alarms and bring older installations up to a more practical standard where needed.
  • Interconnected Alarms
Where appropriate, alarms can work together so an activation in one part of the property is heard elsewhere.
  • Testing and Maintenance
Check operation, condition and alarm response and identify units that need attention.
  • Renovations and Electrical Work

Renovations and Electrical Work – Smoke alarm work can be coordinated with other residential electrical upgrades through the same CGF team.

Fire and Rescue NSW recommends testing your smoke alarms once a month by pressing the test button, and replacing removable batteries every year. Alarms with a built-in 10-year lithium battery don’t need battery changes, but the whole unit must be replaced when it reaches 10 years old.

For extra peace of mind, we offer professional smoke alarm testing on a six-monthly or annual schedule, ideal for landlords, strata buildings and businesses. Book a smoke alarm check.

Why Smoke Alarms Are Essential

House fires can spread incredibly quickly, especially at night when occupants are asleep. A properly installed smoke alarm system provides early warning so people can react faster and evacuate safely.

Smoke alarms help:

  • Detect smoke and fire early
  • Improve family and occupant safety
  • Reduce fire related risks and damage
  • Support compliance requirements
  • Provide greater peace of mind
  • Protect investment properties and tenants

Properties without working smoke alarms face significantly higher safety risks. Faulty, outdated or incorrectly installed alarms can also fail when they are needed most.

That is why professional installation and regular testing are essential.

Residential Smoke Alarms

Every level, every hallway outside sleeping areas, every bedroom where required. We design a layout that meets NSW law and, more importantly, actually protects your family. Interlinked photoelectric alarms with 10‑year battery backup come standard.

Commercial & Business Fire Safety

Offices, warehouses, retail spaces and commercial premises all have specific fire safety requirements. We install and test AS 3786 smoke alarms covering work areas, corridors and escape routes, and can check your system as part of a commercial electrical inspection.

Landlord & Rental Property Compliance

Under NSW tenancy laws, landlords must ensure smoke alarms are installed and working at the start of every tenancy, check them annually, replace removable batteries each year and replace alarms within 10 years of their manufacture date. We handle the whole process and provide compliance documentation for your records.

Strata & Apartment Buildings

Strata fire safety is complex. We install systems for individual units and common areas, working alongside strata managers to ensure compliance without the confusion. We understand the split in responsibility between lot owners and the owners corporation and we can advise on what needs doing and who’s responsible for it.

The rules aren’t complicated but they are strict.

Here’s the essentials:

  • Smoke alarms must be installed on every level of a residential property
  • Alarms must be located in hallways outside sleeping areas
  • Landlords must ensure alarms are working at the start of each tenancy and check them annually
  • Alarms should be replaced within 10 years of the manufacture date (required for rental properties)
  • Fire authorities recommend interconnected photoelectric alarms in every bedroom
If you own a rental property, manage a strata building, or just want to make sure your family is protected, we’ll help you understand exactly what’s required and make it happen.
  • Constant beeping or chirping – Usually a low battery or an alarm past its 10‑year lifespan
  • Alarms that don’t sound when tested – Could be a dead battery, a faulty unit, or wiring issues
  • Only one alarm in the house works – Older standalone alarms don’t interconnect. An upgrade to interlinked units dramatically improves safety
  • Outdated ionisation alarms – Fire authorities now recommend photoelectric alarms, which respond faster to smouldering fires and produce far fewer false alarms
  • Hardwired alarms that keep tripping – Often a wiring or compatibility issue with older electrical systems, which our electrical repair team can diagnose
If any of this sounds familiar, we can inspect your system and give you an honest recommendation to repair or replace based on what’s safest, not what’s most profitable.

A smoke alarm isn’t “set and forget.” Dust, insects, ageing components and flat batteries can all stop an alarm from working and you won’t know until it’s too late.

We offer regular maintenance checks for homeowners, landlords and businesses:

  • Full system inspection and professional testing with calibrated test spray
  • Battery condition check and replacement where required
  • Age assessment – any alarm over 10 years old needs replacing
  • Cleaning of sensor chambers to prevent false alarms
  • Compliance documentation for rental properties and strata records

We install, test and maintain smoke alarms for homes, rentals, strata buildings and businesses across Sydney.

FAQs – Smoke Alarm Installation Sydney

Smoke detectors give you early warning when something’s wrong. Instead of reacting after a fire spreads, you get alerted immediately giving you time to act, evacuate, and reduce damage. It’s one of the simplest ways to improve safety instantly.

Smoke alarms should be replaced within 10 years of the manufacture date printed on the unit, or sooner if they’re going off randomly or not sounding when tested.

Yes, CGF Security can install, replace, and upgrade smoke detectors to meet current safety requirements. They make sure everything is positioned correctly and working properly so you’re not just compliant, but actually protected.
Smoke detectors should be placed in key areas like bedrooms, hallways, and on every level of the property. Proper placement is critical because even the best alarm won’t help if it’s installed in the wrong spot.
Absolutely. Interconnected alarms all trigger at once, so no matter where a fire starts, you’ll hear the alert throughout the entire property. It’s a big upgrade in safety compared to standalone alarms.
