FAQs
Why should I choose hard-wired (electrical) smoke detectors instead of battery-only models?
Hard-wired smoke detectors are permanently connected to your home’s electrical circuit, so they receive constant power and don’t rely solely on batteries. They still include a back-up battery, but the mains supply dramatically reduces the risk of a dead detector. In addition, hard-wired units can be interconnected so that when one alarm activates, every alarm in the house sounds, giving occupants maximum warning time. For families in Cowan looking for higher reliability and enhanced safety, an electrical smoke detector is the preferred choice.
Are your smoke detectors compliant with New South Wales regulations and Australian Standard AS 3786?
Yes. All of our smoke detectors are third-party tested and certified to meet Australian Standard AS 3786:2014 and comply with the NSW Environmental Planning & Assessment Regulation 2021. This ensures correct sensitivity levels, audible alarm volume, and durability. Our licensed electricians understand the local Cowan council requirements and will install the alarms in the correct locations (on or near the ceiling, away from corners, and on every level of the dwelling) to keep your property fully compliant and safe.
Do you provide professional installation in Cowan, and what does the service include?
Absolutely. Our qualified, insured electricians service the entire Cowan area. A standard installation includes: (1) an on-site assessment of optimal alarm placement, (2) safe isolation of the chosen circuit, (3) mounting and hard-wiring of each detector, (4) interconnection testing so every alarm activates simultaneously, and (5) a full customer hand-over with a demonstration and maintenance guide. Most homes require 2–4 detectors, and a typical job is completed in under two hours with minimal disruption.
How often should I test and maintain my smoke detectors?
We recommend pressing the test button on each detector once a month to verify the horn and interconnection. Replace the back-up battery every year (or sooner if the unit chirps). Vacuum around the alarm grille every six months to remove dust that can affect sensitivity. Our team offers an affordable annual inspection plan in Cowan that includes functional testing, cleaning, battery replacement, and verification that the device is still within its 10-year service life.
What is the expected lifespan of a hard-wired smoke detector, and when should it be replaced?
Both NSW regulations and AS 3786 stipulate that smoke alarms must be replaced 10 years from the date of manufacture, even if they appear to be working. Over time, the sensing chamber degrades and becomes less responsive to smoke. We mark the installation date on every unit and include a free reminder service to notify you when replacement is due. Upgrading at the 10-year mark ensures you always have the latest technology and full sensitivity.
Can I interconnect existing battery alarms with new hard-wired units, and what are the costs?
Yes. If your current battery alarms have wireless interconnect capability, we can supply hard-wired detectors with compatible RF modules so all devices talk to each other. Alternatively, we can run low-voltage signal cabling between new electrical units and leave your old battery models as secondary stand-alone alarms. Pricing varies by house size and cabling access, but a typical three-detector hard-wired supply and installation package in Cowan starts from $449, inclusive of GST and compliance certificates.
