Smoke Alarm Installation Sydney — NSW-Compliant Photoelectric Alarms

NSW Environmental Planning and Assessment Regulation 2021 (cl 146) requires every residence - owner-occupied, rental and strata - to have working smoke alarms on every storey, in every bedroom, and in hallways serving bedrooms. Rental properties must have them interconnected (one alarm triggers them all) and the landlord is legally required to test annually and replace within 2 business days of becoming aware of a fault. Strata schemes carry the same obligation for common-property alarms. Standalone 9V battery alarms - even new ones - don't meet the interconnection requirement for rentals or two-storey homes.

Tradetek installs only photoelectric alarms compliant with AS 3786:2014 - Fire & Rescue NSW specifically recommends photoelectric over ionisation because they detect the slow smouldering fires (couch cushions, electrical insulation) that kill most NSW victims, hours earlier than ionisation alarms. We use Brooks, Quell and Clipsal/PDL hardwired 240V interconnected alarms with 10-year sealed lithium battery backup - the configuration that passes every NSW rental inspection, strata audit and pre-sale building report.

Sydney 2026 pricing: single 240V photoelectric alarm replacement (existing wiring in place) from $189; full home upgrade from battery-only to 240V interconnected, 2-storey 3-bedroom Sydney house typically $590-$890 supplied and installed (3-4 alarms); 10-year sealed lithium interconnected (no mains wiring required, ideal for older homes where wall sheeting can't be opened) $145 per alarm installed. Strata and multi-dwelling jobs quoted on site.

Every install includes: positioning per AS 3786 (300mm minimum from corners, ceiling-centre preferred, away from kitchen and bathroom steam), interconnect commissioning (button-test that triggering one alarm sounds all), labelling, decommissioning of any superseded ionisation units, and a written compliance certificate suitable for rental managing agents, strata committees and conveyancers.

Coverage: all Sydney metro, Northern Beaches, North Shore, Eastern Suburbs, Inner West, Hills District, Sutherland Shire, the Central Coast and Newcastle. NSW licensed electrical contractor (Lic. 388103C). Same-week appointments standard; rental/strata urgent compliance jobs prioritised within 48 hours when a notice has been served.
