WHAT WE DO
NSW law requires working smoke alarms on every level of every home. We supply and install hardwired 240V or 10-year lithium alarms - interconnected, compliant, and ready for inspection.
SMOKE ALARMS · CASTLECRAG
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
We map every storey and habitable room, note existing alarms and expiry dates, and quote the compliant layout.
Hardwired to the lighting circuit with 240V backup, or 10-year sealed lithium where wiring isn't practical.
All alarms interconnected wirelessly, tested with real smoke, and confirmed to trigger every unit in the house.
Compliance certificate issued for landlords or homeowners, with photos of every alarm and the install date recorded.

SYMPTOMS & CAUSES
OUR PROCESS
Same repeatable sequence on every job — no shortcuts, no surprises, no invoices you didn't agree to.
We check every bedroom, hallway and level for coverage, alarm age and interconnection status.
We spec AS 3786-compliant photoelectric 10-year alarms, interconnected via mains or wireless mesh.
Old alarms removed, existing wiring inspected, and any 9 V bases decommissioned.
New alarms mounted per manufacturer spacing, terminated to the lighting circuit, and paired to the interconnect group.
Trigger one alarm and confirm every alarm on the property sounds within 10 seconds.
Typical on-site duration: about 2 hours, depending on access and switchboard condition.
