Learn more by watching our CLIPSAL 755PSMA4 | Photoelectric Smoke Alarm 240v/9v GEN 4 video.
The Clipsal 755PSMA4 is a 240V mains-powered photoelectric smoke alarm with 9V battery backup, surface-mounted to the ceiling and certified to AS 3786:2014. It's the GEN 4 unit in the Clipsal 755 FireTek series and the direct, drop-in replacement for ageing 755PSMA, 755PSMA/2, 755RLPSMA2, 755SMA and PDL SD100 alarms. Same base plate. Same wiring. No ceiling repairs.
Photoelectric detection picks up the slow, smouldering fires that cause the most house-fire deaths in Australia. The 755PSMA4 is ActivFire-listed, complies with the Building Code of Australia, and meets the QLD smoke alarm legislation for all properties leased or sold in Queensland since 1 January 2022.
Wire up to 40 alarms together for whole-home interconnected protection — or go wireless with the 755RFB2 base when you can't pull cable. Add a 755RB relay base to trigger an external siren, strobe or smart-home system.
It's the unit specified in most Australian new builds since the early 2000s. It's also the alarm sparkies keep coming back to — "trust in your brands, these hardly fail, very few call backs."
Queensland Smoke Alarm legislation
The new QLD smoke alarm legislation started on January 1st 2022. All properties leased or sold in Queensland must be fitted with photoelectric, interconnected smoke alarms in all bedrooms of the home, as well as hallways or between areas containing bedrooms and on each storey of the dwelling.
(755PSMA4)
Yes. The 755PSMA4 is backwards compatible with the 755PSMA, 755PSMA2, 755RLPSMA2, 755SMA mounting bases — and with the PDL SD100. In most cases it's a true direct swap onto the existing base plate and wiring, with no ceiling repairs required. As one Sparky Direct customer put it, "It was nice to use the old wiring, and even the old holes, so no ceiling repairs required."
Smoke alarms have a 10-year lifespan under Australian Standards and must be replaced once that period is reached, regardless of whether they appear to still be working. The 755PSMA4 carries a 5-year Schneider Electric product warranty.
Yes. The 755PSMA4 is a photoelectric, interconnectable, 240V mains-powered alarm with battery backup, satisfying the QLD smoke alarm legislation that has applied to all properties leased or sold in Queensland since 1 January 2022.
Up to 40 alarms can be wired together, with a maximum wire length of 150 metres between the first and last unit. The same 40-alarm limit applies when interconnecting wirelessly via the 755RFB2 base.
Yes, when paired with the optional 755RFB2 wireless mounting base. This avoids running new cable through existing ceilings — ideal for retrofits and renovations.
Yes, when installed on the optional 755RB relay base. The relay base provides a voltage-free changeover contact for triggering lights, sirens, strobes or home automation systems.
Sparky Direct reviewers consistently report low false-alarm rates: "does not alarm when using the stovetop," "Found smoke alarm to be free from false positives," "These smoke alarms do not seem to have false alarms compared to others." The built-in stainless steel insect screen and modern optical chamber design help reduce nuisance triggers from dust and insects. The Test/Hush button silences nuisance triggers (such as cooking smoke) for 10 minutes.
No. The 755PSMA4 is a hardwired 240V mains-powered alarm and must be installed by a licensed electrician under Australian electrical regulations.
On the ceiling, centred in the room where possible, and at least 1 metre from air conditioner/heater vents, ceiling fans, electrical appliances and fittings. Do not install in garages, kitchens, bathrooms or any high-moisture or high-dust area. Stairways should always carry an alarm — they act as chimneys for smoke and heat.
The 755PSMA4 uses a replaceable 9V battery for backup. The 755RLPSMA4 uses a sealed-in 10-year rechargeable lithium battery, so there's no annual battery change. Both share the same photoelectric core and mounting compatibility
The 755PSMA4 is the genuine Clipsal/Schneider OEM option — the unit that has been overwhelmingly installed in Australian new builds since the early 2000s.
The Red R10RF and PSA LIF6000 are aftermarket photoelectric alternatives.
The 755PSMA4 is chosen by customers who specifically want direct-swap compatibility with existing Clipsal 755-series base plates, or who want to standardise on a single specified brand across a project.
As a reviewer noted: "As recommended by my electrician, I replaced my existing Clipsal smoke alarms with them after 10 years. A brand trusted by electricians and a quality lasting product."
Across 220+ Sparky Direct reviews, three themes dominate.
It's the straight swap. Sparkies and homeowners hitting the 10-year replacement point overwhelmingly buy the 755PSMA4 because it lands directly on the old Clipsal base plate — no re-wiring, no fresh ceiling holes, no plaster repairs. "Easy upgrade for existing out-of-date Clipsal smoke alarms. Great value and no messing about with base plate and in-ceiling wiring."
Tradies trust the brand. "Trust in your brands, these hardly fail, very few call backs." "You cannot go wrong with the CLIPSAL brand." For working electricians, callback risk on a smoke alarm is reputation risk — and the 755-series has decades of installed-base credibility.
Sparky Direct ships fast at trade prices. "Great all round service — at Tradie rates!" "Surprisingly, I received the 2 smoke alarms the very next day." "Best value for money smoke alarms on the market and a good brand you can trust."
