WHAT WE DO

Smoke Alarms in Liberty Grove - what's included

  • Hardwired 240V photoelectric alarms with battery backup
  • 10-year sealed lithium alarm supply and install
  • Interconnection of alarms across the whole home
  • Rental property compliance certificates
  • Replacement of expired alarms (10-year life)
  • Heat alarms for kitchens and garages

SMOKE ALARMS · LIBERTY GROVE

Smoke Alarms in Liberty Grove — done properly, first visit

In NSW the law is simple: every home must have at least one working photoelectric smoke alarm on every storey, and homes built after 1997 must be hardwired. Rental properties need a compliance check before each new tenancy. We install both types — 240V hardwired photoelectric alarms with 10-year sealed lithium backup, or standalone 10-year lithium alarms where hardwiring isn't practical — and interconnect them so when one triggers, they all sound.

Interconnection is the single biggest life-safety upgrade you can make. A fire in the laundry at 3am won't wake someone sleeping at the far end of the house on the top floor — unless every alarm goes off at once. Modern alarms interconnect wirelessly (no wiring between them), so we can retrofit interconnection to any existing hardwired or lithium install in about an hour per alarm.

For landlords and property managers we issue a formal compliance certificate on the same visit, testing every alarm, replacing anything past its 10-year date stamp, and photographing each unit for your records. Heat alarms — the correct sensor for kitchens and garages where photoelectric alarms cause nuisance triggers — are installed where required.

HOW THE JOB RUNS

Every smoke alarms job, same 4 steps

  1. STEP 1

    Compliance walk-through

    We map every storey and habitable room, note existing alarms and expiry dates, and quote the compliant layout.

  2. STEP 2

    Install or replace

    Hardwired to the lighting circuit with 240V backup, or 10-year sealed lithium where wiring isn't practical.

  3. STEP 3

    Interconnect and test

    All alarms interconnected wirelessly, tested with real smoke, and confirmed to trigger every unit in the house.

  4. STEP 4

    Certify

    Compliance certificate issued for landlords or homeowners, with photos of every alarm and the install date recorded.

Signs you need smoke alarms

When to book a smoke alarms sparky

  • You're a landlord and a new tenancy is starting
  • An alarm chirps every few minutes (dying battery or expired)
  • The alarm date stamp on the back is over 10 years old
  • You just bought or moved into an older home
  • There's no alarm on every storey (NSW law requires it)
  • Alarms aren't interconnected — one goes off, the rest stay silent
  • You've had nuisance triggers in the kitchen (needs a heat alarm)

SYMPTOMS & CAUSES

What we usually see with smoke alarms

Symptoms you tell us about
  • Alarm chirping every few minutes (9 V battery flat)
  • One alarm sounds, others stay silent (not interconnected)
  • Ionisation-only alarms in a rental — non-compliant since 2022
  • Alarm past its 10-year replacement date
What actually causes it
  • Old 9 V units rather than 10-year lithium sealed alarms
  • No hard-wired or wireless interconnection
  • Ionisation-only alarms (slower to detect smouldering fires)
  • Alarms installed too close to a kitchen or bathroom

OUR PROCESS

How we handle smoke alarms in Liberty Grove

Same repeatable sequence on every job — no shortcuts, no surprises, no invoices you didn't agree to.

  1. 1

  3. 3

    Isolate and remove

    Old alarms removed, existing wiring inspected, and any 9 V bases decommissioned.

  4. 4

    Install and interconnect
