Emerald is the smoke alarm range from PSA Products, with photoelectric alarms in mains-powered and battery versions. We install and replace Emerald smoke alarms in homes and rentals across the Inner West and Sydney.
Ring 0421 772 661 for a quote. Let us know if your current alarms are Emerald, as that affects what can be swapped directly.
Replacing a hardwired smoke alarm sounds simple, but the details depend on what's on the ceiling now. Older alarms may sit on a mounting base with a plug-in connector, or be wired directly. A new alarm from the same range may connect to an existing base, or the base may need replacing too. That's why we check the existing alarm before quoting a straight swap.
Emerald alarms are a common sight in Sydney homes and are often chosen for straightforward replacements and rental properties. Whether you're replacing a single faulty alarm or a full set that has reached its replace-by date, the goal is the same: every alarm working, correctly positioned and, where interconnected, sounding together.
Blue Link Electrical is a licensed electrician based in Hurlstone Park (NSW Contractor Licence 332956C). Hardwired smoke alarm work must be done by a licensed electrician, and we provide a Certificate of Compliance for it.
Before buying replacement Emerald alarms, look at the label on your current ones: it shows whether the alarm is mains or battery powered, the sensing type and the replace-by date. If the existing alarms are interconnected, all of them need to be compatible with each other after the change, so a partial replacement must use models designed to link with what's staying.
If your home has ionisation alarms, consider replacing them with photoelectric ones, which are generally recommended for homes. We'll talk through options, including whether to add alarms in rooms that currently have none. For the legal side, read NSW smoke alarm rules; we'd rather point you there than oversimplify it.
We check whether the new alarm can use the existing base and connector or needs a new one.
If alarms are linked by an interconnect wire, it's tested and reconnected so the set still works together.
Hardwired alarms are fed from a 240V circuit; we confirm it's sound and protected.
Existing positions aren't always ideal. We'll suggest moving alarms that sit in dead air spaces or near kitchens.
Mains alarms include a backup battery; we confirm it's fitted and active on installation.
1. Inspect. We test the current alarms, read their labels and check the wiring and bases.
2. Quote. A written quote for like-for-like replacement or an upgraded layout, as you prefer.
3. Replace. Circuit isolated, old alarms removed, new Emerald alarms and bases fitted and connected.
4. Test and certify. Each alarm tested, interconnection confirmed, and a CCEW issued for the hardwired work.
Typically a backup battery or end-of-life warning. Our smoke alarm beeping guide covers safe checks.
Bases and connectors change between generations. Replacing the base solves it.
A broken interconnect wire or incompatible replacement. We trace and fix it.
Dust, insects, steam or an ageing sensor. Expired alarms should be replaced.
Sometimes, depending on the models. We check on site and replace the base where needed.
If they were installed together, they'll usually reach their replace-by dates together, so replacing the set is often sensible.
You can replace a backup battery if the alarm is designed for it. Removing or rewiring the alarm itself is a job for a licensed electrician.
They're generally recommended for homes. We can replace ionisation alarms with photoelectric ones.
Yes. We coordinate with agents and tenants. See our landlord electrician page.
